License Manager Error -9: "Your username is not authorized to use this license"

Hello,

I am encountering the License Manager Error -9 while attempting to run MATLAB R2024b using a trial license.

The error message states:

Your username is not authorized to use this license. To resolve this issue, reactivate your license.

The diagnostic information provided is as follows:

• Feature: MATLAB
• License path:
• C:\Users\Admin\AppData\Roaming\MathWorks\MATLAB\R2024b_licenses\
• C:\Program Files\MATLAB\R2024b\licenses\license.dat
• C:\Program Files\MATLAB\R2024b\licenses\trial_13100468_R2024b.lic
• Licensing error: -9,57

I have verified that the .lic file is present in both the licenses directory under the MATLAB installation folder and the user profile folder. I have also tried reactivating the license and setting the MLM_LICENSE_FILE environment variable to the trial license path.

However, the issue persists. Could you please advise on how to resolve this error? Is there a specific configuration or step that I am missing for trial licenses?

Thank you for your assistance.
