: This file is for client computers connecting to a network license server. It is generated during the activation of a network client installation. It contains only a SERVER line and a USE_SERVER directive, pointing the client to the license server. On network client machines, MATLAB uses network.lic to locate the license server. : This file is for client computers connecting
This occurs on network concurrent licenses. The client machine’s license.lic file points to a server IP or hostname that it cannot reach.
MATLAB searches for its license files in specific directories depending on your operating system. If you need to manually replace or inspect your license file, you can find it in the following default paths (where R20XXy represents your specific MATLAB version, such as R2026a): C:\Program Files\MATLAB\R20XXy\licenses\ Use code with caution.
