I am getting a 'You do not have a valid license file' whenever I launch MATLAB after installing even though I have a valid student license.

I get a ' you do not have a valid license file' whenever I try to launch MATLAB. I tried to delete and reinstall it but that did not help. Please note that I have a valid student license and I'm able to use MATLAB online with that license.

The message complaining about the invalid license file should have output a license search path. Delete all of the files in the directories given in the license search path.

At the point, re-activate if you are using a student version. If you are using an educational version, then possibly you do not need to activate at all, just sign in to your Mathworks account.

Hi @Naledi Ntsane,

The issue seems to be related to license information that cannot be read properly or has been corrupted. I would recommend you refer to the following MATLAB Answers post that might be helpful to you : https://www.mathworks.com/matlabcentral/answers/1819010-why-do-i-receive-the-error-you-do-not-have-a-valid-license-file-when-i-try-to-launch-matlab

Additionally, you can also see which license you are using through the following MATLAB command:

>> ver -support

Hope it helps!
