License Activation and Installation Types
There are two license activation types available with Thermo-Calc 2025b: One using a license file that is installed on your computer (this also includes the different network installation types using Sentinel License Management Software), and the new type where user credentials (user name and password) are entered after installation and when you first open (launch) Thermo‑Calc.
This guide is NOT applicable to installations of the Free Educational Package, which does not require a license file and is not currently available with the new license system. Installation instructions are available separately after you request the free version from this page on our website.
Installation procedures are based on the license types, license activation types, installation type, and the operating system.

* A few users will continue to use the License Management Software system for the short term until the change over is complete and implemented in a future release. Until then, users who require an On Premise License Server need to use License File and License Server Activations, see the next section.

Sentinel RMS License Management Software: Use Current Version
The most recent version (9.7) of the Sentinel RMS License Manager (Windows) and License Server (Linux) is included with the network license Thermo‑Calc software download.
However, due to security issues reported by the vendor, it is important that previous network license installations of the Sentinel RMS are upgraded to this version number.
