Installing TC‑Toolbox

There are automatic or manual installation instructions for TC-Toolbox for MATLAB®.

Automatic Installation of TC-Toolbox

When the following conditions are met, Thermo-Calc automatically installs the TC‑Toolbox for MATLAB® component on your computer.

  1. MATLAB® is already installed.
  2. There is only one Windows user on the computer where TC-Toolbox is being installed.

    Administrator privileges are needed when you start the Thermo-Calc installer.

Then follow the regular installation instructions for Thermo-Calc, choosing whether you use a Standalone or Network installation. If required also see Testing a TC‑Toolbox Installation.

A reminder regarding the license. Although you do not need to have a license file during the installation process (it can be added after the fact), you do need to have purchased a license for TC-Toolbox for MATLAB® to run the program within MATLAB®.

Manual Installation of TC-Toolbox

The installation is not automatic if:

  • There are multiple Windows users on the same machine, or
  • The installer cannot find the directory path to the MATLAB installation.

Multiple Windows Users on Same Machine

If there are multiple windows users on the same machine, then the following manual steps are done at the end of the automatic installation.

  1. A message at the end of the Thermo-Calc installation process displays with instructions.
  2. An Explorer window automatically opens to the C:\Users\Public\Documents\Thermo-Calc\2025b\SDK\TC-Toolbox-MATLAB folder.
  3. Double-click the InstallTCToolboxMATLAB.cmd file to finalize the process. This briefly launches MATLAB® and installs TC‑Toolbox. If required see Testing a TC‑Toolbox Installation.

Installer Cannot Find the MATLAB® Installation Directory

If the Thermo-Calc installer cannot find the MATLAB® installation directory,

  1. Start the version of MATLAB® that you want to install TC-Toolbox in.
  2. Open and run the MATLAB® script included with your installation of Thermo-Calc.

    For example on Windows, C:\Users\<username>\Documents\Thermo-Calc\2025b\SDK\TC-Toolbox-MATLAB\setupTCToolbox.m
