Licensing error: -9,57.

Hi,

I am installing Matlab on a HPC on a license holder's user account. I installed and acivated the license. However, when they run matlab, the following error occurs:

MATLAB is selecting SOFTWARE OPENGL rendering.
License checkout failed.
License Manager Error -9
Your username does not match the username in the license file. 
To run on this computer, you must run the Activation client to reactivate your license.

See https://www.mathworks.com/matlabcentral/answers/99067-why-do-i-receive-license-manager-error-9

The license path including /root/.matlab/R2019b_licenses could be a problem: they are obviously on Linux and they would not be running the software as "root" . You might need to adjust the LM_LICENSE_FILE environment variable, or you might need to delete the one in /root so that the software continues on to check the other locations.

Thank Walter. That fixed it.
