### Notes for Installation and Software Activation

A setup program performs the installation of the Client Software quickly and smoothly. The installation procedures for all versions of NCP Client Software are the same. The following text describes the procedures for installing the Client Software under Windows XP, Vista, Windows 7 and Windows 8.

Prior to executing installation, make sure that the following prerequisites are fulfilled.

Starting with version 8.31 the Client will be installed in the program directory of the operating system (programs\NCP\SecureClient) for a new installation.

Old path: %Windows%\ncple
New path: %Programs%\NCP\SecureClient

For an update the path which was entered for the last installation will continue to be used.

Uninstall

If you uninstalled the client, you have the option to keep the configuration and profile settings in the client directory. If at a later date, a newer client version is installed in the same directory, all personal data can be used again. If you want to delete the personal data in the client, you have to confirm this specifically. In such a case all data and directories of the client are removed irretrievably.

Registry repair (RegRep)

The setup program checks the registry entries for each new installation of the client, i.e. even when an older version was uninstalled. If problematic entries are found, they will be altered as necessary. The setup program then generates a message requesting a restart of the PC.

### Prerequisites for Installation

Operating System:

Microsoft Windows XP, Windows Vista, Windows 7 or Windows 8 must be installed on your PC (min. 128 MB RAM). Before starting the installation, ensure that the operating system installation disks are available, as these may be needed for updating your PC's driver database files; insert these disks when prompted to do so.

Important: when updating from Windows 7 to Windows 8

When updating from Microsoft Windows 7 to Microsoft Windows 8, it is vital that the NCP Secure Client be de-installed before starting the update. It is also recommended that backup copies be made of any configuration files and certificates used. When the update to Windows 8 is complete, the latest version of the NCP Secure Client should then be downloaded from the NCP website and installed. Failure to de-install the NCP Secure Client before updating to Windows 8 could subsequently lead to having to carry out a new install of Windows 8.

Remote Destination:

The remote destination has to support one of the following communication media: ISDN, PSTN (analog modem), GSM, GPRS/3G, LAN over IP, Wi-Fi or PPP over Ethernet (PPPoE).

Local System:

One of the following communication devices must be properly installed

ISDN adapter (ISDN)
The device (e.g. adapter internal or external) must support the ISDN CAPI 2.0 standard. When using PPP Multilink the software can bundle up to 8 ISDN B-Channels. Any ISDN device supporting the ISDN CAPI 2.0 can be used. (Usually CAPI is set up automatically during installation of an ISDN adapter.) Analog Modem (PSTN)
For communication via analog PC Modem, the modem drivers have to be properly installed and the Modem Init. String and the COM-Port definition for the modem has to be correct. The modem has to support Hayes AT commands.
Cellphones can also be used for data communication, after the associated software has been installed; software that presents itself to the client precisely as if it were an analog modem. The serial interface, IR (infrared) interface, or Bluetooth can be used as interface between cellphone and PC.The remote side has to have the appropriate dial-in platform depending on the baud rate (GSM, v.110, GPRS or HSCSD). The initialization string in the Secure Client modem configuration must be obtained from the ISP or the manufacturer of the cellphone. LAN adapter (LAN over IP)
When the communication medium LAN (over IP) has been defined, no additional adapter has to be installed since a LAN adapter (Ethernet) is already on the system. The connection of the LAN client to the WAN is set up by any access router. The sole prerequisite: An IP connection to the target system has to be possible. The VPN functionality is supplied by the Client Software.
Adapters for a wireless LAN (Wi-Fi adapter) are handled exactly like normal LAN adapters. Broadband Device (xDSL (PPPoE))
The communication medium PPP via Ethernet requires that an Ethernet card is installed and over which a xDSL modem with splitter is connected correctly. xDSL (AVM - PPP over CAPI)
The communication medium "xDSL (AVM - PPP over CAPI)" has to be selected if an AVM Fritz DSL card is to be used. AVM specific init strings may be entered in the field "Destination Phone Number" ("Dial-Up Network" group) for the connection. It is recommended to use the standard setting "xDSL (PPPoE)" with Windows operating systems as this provides direct communication over the network interfaces. No additional network card is necessary with the AVM Fritz! DSL card. Multifunction card (GRPS / 3G / HSDPA / HSUPA)
If you are using a multi-function card, special features of mobile computing can be used depending on the card characteristics. Due to the direct support of the multi-function card for 3G/GPRS/Wi-Fi through the Secure Client, installation of management software of the card used, is not necessary.
The Secure Entry Client unites all technological mechanisms in the areas of communications and security for economic data communication on the basis of the end to end security principle. The Client Monitor features a graphical display of field strength, connection status and provider name of the selected network.
Starting with Version 9.02 Build 5 the Secure Client supports new PCMCIA cards after importing file g3detect.dll. For currently supported multifunction cards please see the latest compatibility list: http://www.ncp-e.com/en/support/compatibility/umts-3g-hardware.html Wi-Fi adapter (Wi-Fi)
The Wi-Fi adapter can be operated with the communication medium "Wi-Fi". In the monitor menu the special "Wi-Fi" menu item is displayed where the access data for the wireless network can be saved in a profile. If "enable Wi-Fi configuration" is checked, the management tool of the Wi-Fi card has to be deactivated. (If alternatively the management tool of the Wi-Fi card or the Microsoft tool is to be used, the feature "enable Wi-Fi configuration" has to remain unchecked.)
If the communication medium Wi-Fi is set for the profile in the profile setting, an additional area is shown under the graphic field of the Client Monitor where the field strength and the Wi-Fi network are displayed.
Please note for configuring the Wi-Fi settings the description of Mobile Computing. Automatic Media Detection
If various communication media are used alternately, the client detects automatically which communication media can be used currently und selects the fastest one.
On the basis of a pre-configured profile, the communication media that are currently available for the Client PC are detected and used. If multiple communication media are available, the fastest will be selected automatically. The link type priority is specified in the following sequence in a search routine: 1. LAN, 2. Wi-Fi, 3. DSL, 4. GPRS/3G, 5. ISDN, 6. MODEM.
The configuration is executed in the profile settings with the communication medium "Automatic Media Detection" under "Basic Settings". If desired, all profiles for the VPN gateway that are pre-configured for this Client PC can be assigned to this automatic media detection. This renders manual selection of a communication medium (Wi-Fi, 3G, LAN, DSL, ISDN, MODEM) in a profile superfluous.
Input data for the connection to the ISP are transferred from the available profiles in a manner that is transparent for the user.

### Prerequisites for using Certificates

#### Supported interfaces and formats

The secure client can be used in public key infrastructures as of X.509. V.3 standard and supports the following interfaces/formats: - Smartcards, USB-Tokens: PKCS#11, TCOS 1.2 and 2.0, CSP
- Soft Certificates: PKCS#12-file
- PC/SC conform chip card reader: The client software supports all chip card readers which conform with PC/SC. The chip card readers are included in a list of the client once the reader is connected and the corresponding driver software has been installed.
- Automatic recognition of connected PC/SC readers: If the use of a PC/SC chip card reader is configured on the client for the PKI environment, the client recognizes and automatically uses the connected one.
- PKCS#11 module: Drivers in form of a PKCS#11 library (DLL) are supplied with the software for smartcards or tokens. This driver software has to be installed initially. Then the relevant PKSC#11 module can be selected via a wizard.

#### CA Certificates

The administrator of the company network determines which certificate issuers can be trusted. This happens by importing the CA certificate of his choice into the installation directory under . The application can be carried out automatically during software distribution if the issuer certificates are located in the directory during software installation from a data carrier.
Retrospectively, issuer certificates can be distributed automatically via the Secure Management Server (only to Enterprise Clients) or the user can save them himself as long as he has the appropriate write rights in the respective directory.
Currently the formats *.pem and *.crt are supported for issuer certificates. They can be viewed in the monitor under the main menu item "Connection / Certificates / Display CA Certificates".
If the secure client receives the certificate of a remote station, then the NCP client will determine the issuer by searching for the issuer certificate initially on smartcard or USB token or in the PKCS#12 file and finally in the installation directory under . If the issuer certificate cannot be found, the connection set up will not be successful. If no issuer certificates are available, then no connection is allowed.
If soft certificates are created with the PKI plug-in of the management server, the issuer certificate is saved in the PKCS#12 file.

#### Use of a Revocation List (CRL)

The secure client can have access to the corresponding CRL (certificate revocation list) for each issuer certificate. It is applied to the installation directory under . If a CRL is available, then the secure client checks incoming certificates against the CRL. The client downloads the corresponding CRL automatically if the incoming server user certificate includes the certificate extension CDP.
If revocation lists are used, then usually there is no notification if the client has no revocation list for incoming certificates on his PC. If a notification is required in such cases then the file NCPPKI.CONF needs to be edited. It is saved in the installation directory. The default entry in the section [General] is:
Enablecrlinfo = 0
This means that no notifications are displayed if, on the client at the remote station, no revocation list was found for the certificate. If a notification has to be displayed, then this setting has to be changed to:
Enablecrlinfo = 1

### Installing the Client Software

The current version and later versions of the Client will be tested by the quality assurance only according to the operation systems Windows XP, Windows Vista and Windows 7. Full functionality cannot be guaranteed when using the client under Windows 2000, Windows NT, Windows 98 or older Windows versions. You can obtain the software as ZIP file by downloading it from the website under: www.ncp-e.com. The following text describes the procedures for installing the client software under Windows XP, Vista and Windows 7.

#### Installation and Licensing

First the NCP Secure Entry Client is always installed as a test version. If you possess a license, you can enter the license data after a reboot of the software by selecting the monitor menu option "Help/ License Data and Activation". The test version is valid for 30 days. Without software activation or licensing it will no longer be possible to setup a connection after this 30-day period expires. When 10-days validity remain, a message box will be displayed to remind you that the software has not yet been licensed. For licensing the software please refer to the chapter "License Data and Activation" in the handbook.

#### Default Installation

Save the ZIP file you have downloaded onto your PC. The filename of the ZIP file displays the number of the version and the build number of the software, e. g.:
SecEntryClientWinx_xx_yyy.ZIP
(x_xx = Release, yyy = Build)
Extract the ZIP file. After that in the directory SecEntryClientWinx_xx_yyy you can start NCP_EntryCl_Win_xxx_yyy.exe.

In the following window "Choose Setup Language". Select a language for installation in the following window then click "OK". The "Install Shield Wizard" is now started. It will guide you through the installation. Read the terms of the Welcome window carefully and click on "Next". The next window displayes the software licensed agreement. In order to proceed with the installation of the licensed version click on "Yes". Clicking "No" will stop the installation process. Default directory for installation is: Programs\ncp\SecureClient
(Under Windows Vista it could also be:Program Files\ncp\SecureClient) Independent of "Typical" or "Custom" installation you can select any folder for the software installation by clicking on "Browse". This is particularly important if the user should have no rights on the system root directory. If you select "Standard Installation" in this window the installation will continue automatically and the setup is finished. Selecting the "Custom" Installation you can define settings according to your requirements. In the following window of the "Custom" Installation you define the program folder for the client software. (Default setting: "NCP Secure Client"). In the next window you can define whether the program icon should be displayed on the desktop or not. Please contact your system administrator or your internet service provider for additional information about your communication gateway. Communication with DHCP (Dynamic Host Control Protocol) means that a temporary IP Address will be assigned automatically for each communication session. In this case, click on "Obtain an IP Address from DHCP Server". If you "Specify an IP Address", enter the IP address in this window. Default Gateway: If a network adapter with a Default Gateway is already installed, you will have to delete this Default Gateway Address. It is not possible to have more than one network adapter with a Default Gateway. DNS Address: You should only enter a DNS Address if you have been assigned one from your system administrator or ISP. Thereafter you can define whether a logon to a remote domain should occur after establishing a connection to the VPN gateway. This may necessitate entering the PIN for your certificate and your password for the client software (without it being saved). After establishing a connection to the remote destination's NAS, you can logon to the remote domain. This logon will be encrypted. Please note: If you activate this option before the Windows logon, the NCP Gina (or Credential) will also be automatically installed. The logon options can only be used if the NCP Gina is installed after the Windows Gina. This option is available in this setup window. These logon options can be set via the Monitor menu of the Client under "Configuration". If the logon option is not activated here, and if the NCP Gina is to be used at a later point in time, it can be permanently installed after this setup using the command
rwscmd /ginainstall Now the data is copied from the installation CD or removeable disk amd associated network components are installed. This completes the installation of the Client Software. Click the "Finish" button. Before using the Client Software it is necessary to reboot your PC. Click on "Yes, I want to restart my computer now" and then click on "Finish" to reboot your PC.

#### Wizard for First Configuration

Once you have installed the Client Software and rebooted your PC, the Client Monitor will be automatically started on your PC. The "Initial Configuration Assistant" will also be displayed, provided that you have installed the Client Software for the first time on your PC or you have deleted the profile settings. They are located in the installation directory.

If you do not use the assistant for creating such a test profile, then no entries will be added to the profile list. In this case you will have to create your own profiles, as described in the chapter "Client Monitor" fo the manual. If you use the assistant, click on "Next". Then an IPsec test profile will be added to the client's profiles and the assistant will guide you through the definition of generic parameters. The following access data are created automatically: VPN protocol is IPsec, the Tunnel Endpoint of the VPN gateway is: vpntest.ncp-e.com, XAUTH user ID and password is "ncpIPsecnative". The IP address of the DNS server is 172.16.12.100. The communication medium is LAN. If a connection via an ISP should be established, the parameters for dial-up must be configured in the profil settings of the test connection. Setting up the variant with strong security you can use the test certificate enclosed. The PIN of the test certificate is "1234" and has to be entered when establishing the connection. Once you have saved the test configuration, you can set up immediately a test connection (in LAN mode) by clicking the "Test" button. For further configuration of a profil refer the description under "Client Monitor, Profil Settings" and "Configuration Parameters, IPsec Settings".

#### Testing for Internet Availability

Network Tests are an option the Client Monitor's Help Menu and these can be used to test Internet availability. They support both PING to an IP Address in the Internet as well as resolution of an Internet Domain Name to an IP address. Domain names should be of the form "ncp-e.com".

Enter the address and press the corresponding Test button. The test results are displayed via a symbol (success: green tick, failure: red cross). More details are displayed in a clear text log. The tests are particularly useful for testing firewall rules for DNS requests and outgoing connections to the Internet.

#### Tests with the Entry Client

After the test connection and the tunnel to the VPN gateway has been established you can execute the following tests.

##### Testing with Ping

Enter the following command at the DOS prompt:
C:\>ping 172.16.12.100 (ENTER)
Upon successful pinging your reply will look something like this:
Reply from 172.16.12.100: bytes=32 time=109ms TTL=128
Reply from 172.16.12.100: bytes=32 time=96ms TTL=128

##### Testing Web Browser functionality

You can also make a test connection to the Web via the existing VPN tunnel link by entering 172.16.12.100 in your Web Browser.
This should connect you to NCP's Web Site.

### Activation

The "Help" Monitor menu item shows the software version, and possibly the licensed version with serial number under the menu option "License Data and Activation".

The client software is always installed as a test version if the client software has not yet been installed, or if there is a previously installed older version, which has not yet been activated. This also applies if an older version has already been licensed - then this older version will be reset to the status of a test version, and the license data must be re-entered within 30 days using the activation dialog. The time remaining until software activation, i.e. the validity period of the test version, is displayed in the message bar of the monitor next to the activation button. In order to use a full version with no time limitations the software must be released in the activation dialog with the license key and the serial number that you have received. With activation you accept the license conditions that you can view in the activation dialog after clicking on the appropriate button. The activation dialog can be opened using the activation button in the message bar of the monitor, as well as using the the monitor menu "Help / License Data and Activation". The license data can be entered either online or offline using a wizard. In the offline version, a file that is generated after entering the license key and serial number has to be sent to the NCP authentication server, and the activation key that will be displayed on the web site has to be recorded. This activation key can be entered in the licensing window of the Monitor menu at a later point in time. In the online version, a wizard forwards the licensing data to the web server immediately after entry and in this way the software is released immediately.

#### Test Version Validity Period

The test version is valid for 30 days. Without software activation or licensing it will no longer be possible to set up a connection after this 30-day period expires.

After installation, each time the software is started the validity period will be shown in the pop-up window. Moreover in a footer of the monitor the system will display how long the test version can still be used, and when 10-days validity remain, a message box will be displayed to remind you that the software has not yet been licensed. This message box will appear once a day. When the trial period has expired, only those connections can be setup with the Entry Client software that are used for software activation/licensing. Thus one of the profiles of the Entry Client can be used to set-up an Internet connection for licensing purposes. Or a connection to the NCP Secure Enterprise Management can be established in order to download a licensed version of the software. Important:
Installation under the operating system Windows 7 demands a license key of version 9.20.
In case of an update from Windows Vista to Windows 7, the monitor of a Client version 9.2, licensed with a license key 9.1, can only be started in order to enter a license key of version 9.2.

Activation of the Client Software under Windows Vista requires a license key of version 9.0 at least. If you are entitled to a free-of-charge update to version 9.0, you receive the affiliated license key when carrying out software activation. In order to purchase the update to version 9.0 please contact your reseller.

### Software Activation

When the test phase has expired the software must be either activated or de-installed.

To activate, select the menu option "License data and Activation" in the monitor menu "Help".Here you can see which software version you have and how the software is licensed, i.e. you can see that the test version has expired and that the software has not yet been activated/licensed. Click on the license conditions to display the license agreement text. By activating/ licensing the software you accept the license conditions. Click on the "Activation" button to license the software. In the window that appears, select whether you wish to activate the client online or offline by selecting "Online Activation" or "Offline Activation". In the offline version, a file that is generated after entering the license key and serial number has to be sent to the NCP activation server, and the activation key that is then displayed on the web site must be noted. In the online version, a wizard forwards the licensing data to the web server immediately after entry and in this way the software is released immediately. After selecting the type of activation the license data is to be entered in the appropriate fields. Click on "Next"!

#### Online Version

With the online version the license data will be transmitted to the NCP Activation Server via an internet connection. This Internet connection can either be established via the Data Communications Dialer, via DSL, or via the Entry Client.

If the Internet connection is not set up via the Entry Client, the connection must first be established in order to then start the activation wizard via the Monitor menu option, "Help" / License Data and Activation". If the Entry Client is used to set up the connection to the internet, a suitable profile must first be established for the Entry Client. Ensure that port 80 is released (for HTTP) if the firewall is activated. (If a proxy server has been configured in the operating system, then these settings can be transferred.) After the profile has been selected, click on "Next" to continue. The internet connection via the Entry Client does not have to be set up prior to activation. It is set up automatically after the desired existing profile has been selected in the assistant for software activation, and after clicking on the "Next" button. The software is activated automatically in the specified sequence: As soon as the activation server detects that you are entitled to a newer software license and that the license key agrees with the installed software, then with online activation the new license key will be transferred automatically (license update), and in this way the new features of the software will be released. Please see the section "Updates" at the end of this section for more information. After concluding the activation process, in the window for the license data you can see that you now have a correctly activated full version. The number of the software version and of the licensed version should not differ. If they do, the license has to be updated with a newer license key. To do this click on the "Licensing" button. For more information see the description at the end of the offline version.

#### Offline Version

The offline version is executed in two steps. In the first step a file is generated after entering the license key and serial number, and is sent to the NCP activation server. The URL is:
http://www.ncp-e.com/en/support/software-activation.html
An activation key will be shown on the web site, and you have to write down this number in order to enter the license key in the licensing window of the monitor menu in a second step. This can also be executed at a later point in time.

The offline version is initiated via the monitor menu "Help / License Data and Activation", and this version can be selected in the first window of the activation wizard. Click on "Next". In the second window of the activation wizard the two steps of the offline activation process are explained. The first step, creation of the activation file is selected automatically. Click on "Next" to continue. In the following window enter the license data and click on "Next". Enter name and path for the activation file. As default, the installation directory of the software and the name ActiData.txt (with serial number) are used. Now the activation file is created and this file has to be transferred to the Activation Server. For this the NCP web site has to be opened:
http://www.ncp-e.com/en/support/software-activation.html There are two ways to transfer the activation file to the Activation Server. Either copy the content of the activation file with Copy & Paste, after you have opened the activation file with the Notepad (ASCII editor), into the window that is open on the web site, or click on the "Browse" button and select the activation file. Click on "Send"! Then the activation code is generated and displayed on the web site. Write down the activation code and continue the activation process under the menu option "Help / License Data and Activation", by executing the second step of the activation in the offline version. If the Activation Server detects that you are entitled to a newer software license and that the license key agrees with the installed software, then with the activation the new license key will be displayed automatically. If you want to activate the new features then write down the new license key, conclude the activation process, and then use the new license key. The second step of the offline version is triggered via the monitor menu "Help" "License Data and Activation". After the offline version has been selected, select the second step. An activation wizard opens where you can enter the activation code. After you have entered the activation code, click on "Next". Offline activation is completed with the following window. After concluding the activation process, you will see that you now have a correctly activated full version, in the window for the license data. The number of the software version and the number of the licensed version can differ. If they do, the licensing is only valid for an older version. If you have received a new license key from the Activation Server during the offline activation process (see above in the display of the activation code), then enter this license key for a license update, by clicking on the "Licensing" button. In next window of the wizard, enter the new license key and click on "Next". The license data will be verified and then transferred. Click on "Finished" when the verification has been concluded. In the window with the license data you will see that the number of the software version and the number of the licensed version now agree.

#### Automated Search for New Software Update

If the menu item "Search for Updates" is called, a new dialog is displayed via which the search cycle (never, daily, weekly, monthly) can be configured. In addition there is a new button "Search now".

#### Updates

Under the menu option "Check for Updates" in the Monitor menu under "Help" you can check whether a version of the software that is newer than the version you have installed is available at NCP. This is also possible if a test installation has been installed. If a newer version is available at NCP, then a software update is always possible.

The software update has to be purchased if the newer version is a major release, which is indicated by the change on the first decimal place. For example: If a version 8.26 is installed and the next software version has the number 8.3 then a software update from 8.26 to 8.3, as well as use of the new features, has to be purchased. The new features can only be used if the new license key was activated as described above under software activation. The new license key is generated by entering the serial number and the update key that can be purchased locally from the reseller, on the following web site: http://www.ncp-e.com/en/support/update-key.html The software update always available free of charge if the newer version is a service release, which is indicated by the change of the second decimal place. For example: If version 8.26 is installed and the next software version has the number 8.27, then a software update from 8.26 to 8.27, as well as use of the new features, is free of charge. The new features can be used without activation with 8.2x license key, as soon as the new software has been installed. A service release contains bug fixes, an extension of hardware support and compatibility extensions.

#### Software Updates

After you have selected the menu option "Check for Updates" the software update wizard opens, which helps you to search for available updates. You need an internet connection in order to do so. If the Entry Client is be used to set up the internet connection, ensure that port 80 (for HTTP) is released if the firewall is enabled.

If a proxy server is to be configured in the operating system, these settings can be transferred. If the proxy settings are correctly configured, click on "OK". The wizard now searches for newly available software updates via the internet connection. If a software update is available, it is displayed. (It may well be that the versions only differ in regard to the build number.) Click on "Next" if you want to use the more current version. This downloads the installation package for the latest software. Click on "Finish" to end the Monitor and start the installation of the software update. After starting the Install Shield Wizard select the installation language (as you would for the standard installation), and then confirm the update process with "Yes". Then the installation will be executed automatically. It is concluded when you reboot the computer.

#### Updateing and Uninstalling

If you are already using a previous version of the Software it will be detected when attempting to install the new Client Software. If this is the case, you will be asked if you wish to update your current Client Software to the newer version now in your possession. During the update the current profile settings, certificate data and call control manager statistics will be applied to the new client. (If other programs are still running, they will be stopped.)

In order to uninstall the Client Software go to: "Start / Settings /Control Panel". Select the client from the list of programs and then click on the "Add/Remove" button. The Uninstall Shield wizard will now delete the client software from your PC. Important: After the removal of the software components, the profile and configuration settings are still stored on the computer and can be restored if a newer version of the client is installed. In order to completely delete everything, you have to manually remove the files from the installation directory.
