How do I find my MathID with MathLM?

Your MathID is a unique identification code for your computer used to tie your license information to your specific machine. You will need your MathID when updating and upgrading your Mathematica License Manager (MathLM) server’s license information.

To generate the MathID associated with your machine, you need to have MathLM or Mathematica installed.

During Installation

Your MathID is made available during the MathLM installation process.

Windows

On Windows systems, the MathID is displayed in the first text field in the MathLM Password window.



Linux/macOS

On Linux and macOS systems, you will find your MathID near the end of the Installer introductory text.
