License Manager Error -9 Your username does not match the username in the license file.

Hello, I changed my operating system from windows to ubuntu and reinstalled MATLAB (on the same laptop). I'm using a students license and when I was asked for my User Id, which is 'abc' I typed 'Abc92'. Is there a way of changing it? Because when I want to start Matlab the following Error: 'License Manager Error -9 Your username does not match the username in the license file.' appears.

Thanks in advance :)!

EDIT: I just created a user 'Abc92' and here I can start Matlab, but I want to change the username to 'abc'.

The two most common causes of License Manager Error -9 are:

The MATLAB license file was activated for a different computer and/or user account You have a Designated Computer MATLAB license and MATLAB is already running under a different user account on this computer MATLAB was activated for a different Computer and/or User Account More specifically, this means that the host ID specified in the license file is not the host ID of the computer. If you are using an Individual license, this may also indicate that the login name specified in the license file does not match the logged-in user account.

To resolve this issue, you need to reactivate MATLAB using the correct host ID/Username:
