It is primarily used for manual activation, offline installations, or as an unprocessed file for setting up a Network License Manager . 1. Types of license.lic Files The purpose of the file depends on your license type:

Secure Your license.lic File: Since the license.lic file grants access to MATLAB, ensure it is stored securely and only accessible to authorized users.
Beyond mere access control, the license.lic file also reflects the ethical and economic foundations of software engineering. Attempting to edit or bypass this file—for instance, by altering an expiration date or duplicating a network license for unauthorized users—constitutes software piracy. Such actions violate the MathWorks Software License Agreement and expose individuals and organizations to legal liability, financial penalties, and reputational damage. Conversely, proper use of the license.lic file ensures that developers receive fair compensation for their work, which in turn funds continued innovation, bug fixes, and technical support. In academic settings, special license.lic files for teaching or research often have lower costs but stricter usage restrictions, promoting learning while respecting intellectual property.
