How to renew your license if you do not have access to the MIT MATLAB Portal

Note: This article is for users who are unable to access the MIT MATLAB Portal. If you can log into that portal, please renew your license that way.

Make sure you have made a note of the License Number and have downloaded the Activation Key (certificates required).

• Students: https://downloads.mit.edu/released/matlab/acl/student/license-key.txt
• Faculty/Staff: https://downloads.mit.edu/released/matlab/acl/faculty-staff/license-key.txt

If the Total Academic Headcount License you are using has been renewed, you will need to update your license file to continue using MATLAB.

1. Open MATLAB (If the license has already expired the activation client will launch and you can skip the next step)
2. Navigate to Help Menu and select Licensing
3. Click on  Activate Software
4. Choose to Activate using Internet
5. Once reactivated you will need to restart MATLAB before the new license file is recognized

Please note: 

After updating the license, you may need to restart MATLAB in order to implement the change.

• If you still receive a warning after performing the steps below, then there may be multiple license files on your computer.
  • According to the MathWorks, on startup MATLAB looks for the first valid license. If you have activated the new license, MATLAB should begin to use it once your old key expires on August 1.
• To resolve the issue, remove any additional license files that are about to expire.
  • For help finding your license files, please see the following article:
