It contains encrypted passcodes for the specific products and toolboxes you are licensed to run. Types of license.lic Files The role of this file depends on your license type:

• Host ID Mismatch: If you replaced your computer's network card, the Host ID (MAC address) changes. You must reactivate the license on the MathWorks website to generate a new license.lic for the new hardware.
• Expiration: Check the file header (sometimes readable) or your MathWorks account to see if the annual maintenance has expired.
• Wrong File Type: Attempting to use a "Standalone" license file on a "Network" license manager setup (or vice versa) will cause immediate failure.

SERVER Line: Only for network licenses.

By default, your license file is stored in your MATLAB installation folder under /licenses/ license.lic matlab
