Unattended or Silent Network Client Installations (License File)

This section is applicable to installations involving a license file activation type. This licensing method is gradually being replaced by the user credentials activation type starting with Thermo‑Calc 2025a.

Terminology note: The use of the term license server (lower case letters) is applicable to the option files as described in this section. For the purposes of the step-by-step instructions it is not used to refer to the type of network installation that runs the licensing software.

Sometimes it is convenient to install Thermo‑Calc network clients without providing user input after the installation is initiated (an unattended network client installation), i.e. a silent installation. This is available for Windows and Linux operating systems.

Make sure you know the name or IP number of the computer where the licensing software and the license file are to be installed.

Step 1. Create an Option File in a Text Editor to Enter the Options

The following is an example of an option file for a custom network client installation, where <name/IP number> is the name or IP number of the computer where the license file is installed:

installation_mode=custom

setup_type=client

enable-components=thermo,databases,tq,toolbox,tcpython

icons=1

license_server=<name/IP number>

Below is a shorter example, specifying that a full Thermo‑Calc network client should be installed:

installation_mode=full_client

license_server=<name/IP number>

Step 2. Go to the Directory Where the Installation File is Saved

Thermo‑Calc can only be installed in unattended mode from the command line prompt.

Start the installation in unattended mode using the option file created with this command:

  • Windows: <installationfile>.exe --mode unattended --optionfile <path\optionfile>
  • Linux: <installationfile>.run --mode unattended --optionfile <path/optionfile>

To see other options when you start the Thermo‑Calc installation program from the command line prompt, run this command:

  • Windows: <installationfile>.exe –-help
  • Linux: <installationfile>.run –-help
