Client Customizer


This software lets you create customized ThinLinc client installation programs. This means that when users install the customized version, they will automatically get the default settings you have configured.

One advantage with this is that you can provide, for example, a default server name. A custom client can also be used to enhance security: You can distribute SSH host keys with the client itself, so that users don’t need to be concerned with SSH host key fingerprint verification.


The Client Customizer only works for the Windows client.


Before you can start, you have to install the build environment. This is done by running the command tl-x.y.z-client-customizer.exe located in the Client Bundle. This will also create a shortcut to the build directory in the Start menu.

Building a Customized Client

To create a customized client, do the following:

  1. Edit settings.reg. This file contains all the parameter names and default values that are used in tlclient. To customize the client, edit any of these values, and they will be installed in the registry when you install the customized client itself. You can also add your servers SSH host keys (see below).

  2. Custom branding can be added to the client by simply dropping a file called branding.png in the root directory of the Client Customizer. See Adding Custom Branding to the ThinLinc Client Login Window for more details.

  3. Run build.bat in the same directory. The file setup.exe will now be created. This is the installation program for the customized client.

Adding SSH Host Keys

To add your servers SSH host key to settings.reg, do the following:

  1. Use tlclient to connect to your server, if you haven’t already done so. Confirm the servers host key, if necessary.

  2. Run the registry editor, and select HKEY_CURRENT_USER\Software\Cendio\ThinLinc\tlclient\KnownHosts

  3. Export this key to an external text file.

  4. Open the text file from the previous step in an editor.

  5. Copy the line corresponding to your ThinLinc server. Paste this line into settings.reg, section HKEY_LOCAL_MACHINE\Software\Cendio\ThinLinc\tlclient\KnownHosts

  6. Save settings.reg, and proceed to create the customized client as described above.
