: Specifies the path to the MathWorks license daemon ( MLM.exe on Windows or MLM on Linux/macOS).
If you have multiple licenses and need to point MATLAB to a specific one, use the startup flag: matlab -c "C:\path\to\your\license.lic" Mac/Linux: license.lic matlab
At its core, the license.lic file serves as the definitive proof of license for a MATLAB installation. When a user or an institution purchases a license from MathWorks, they receive this file, which contains encrypted and plain-text information that the MATLAB license manager (typically FlexNet Publisher) reads at runtime. Without this file, MATLAB will only operate in a limited demo mode or refuse to launch entirely. The file is essentially a cryptographically signed contract between the user and the software vendor; it tells the local machine or network server which products (e.g., Simulink, Image Processing Toolbox, Optimization Toolbox) are permitted to execute. This mechanism prevents unauthorized usage and ensures that users only have access to the features they have legally acquired. : Specifies the path to the MathWorks license daemon ( MLM

For new installations or renewals, you must retrieve a new license.lic file from the MathWorks License Center .
