If MATLAB will not launch

If you have an expired or otherwise unusable license, MATLAB may not be able to launch. In this case, you will need to launch the MATLAB activation client directly. To find the MATLAB activation client on each OS:

Windows

The activation client is located here:

C:\Program Files\MATLAB\R20XXx\bin\winXX\activate_matlab.exe

Mac

• Open Finder.
• Go to "Applications".
• Right-click or control-click on the MATLAB application icon. (e.g. MATLAB_R2015b.app)
• Click on "Show Package Contents".
• Open "Activate.app".

Linux

The activation client is located here:

/usr/local/MATLAB/R20XXx/bin/activate_matlab.sh
