Update Your Standalone MATLAB License

The MATLAB Standalone license expires on August 31 each year. Prior to expiration, Computing Services receives a new license file and updates that file on our license server.

  • If you run MATLAB by connecting to our network server, the license file will be updated automatically; no action is necessary on your part and you should no longer receive expiration messages.
  • If you use a stand-alone version (installed on your computer) of MATLAB, follow these steps to update your license.

Update the License

  1. Confirm that you have a network connection.
  2. Launch MATLAB.
  3. In the Resources section of the Home tab, select Help* >Licensing > Update Current License. This will download the latest license file.

If the above steps are unsuccessful, do the following:

  1. Download the license file.
  2. In the Resources section of the Home tab, select Help* > Licensing > Activate Software.
  3. Select Activate automatically using the internet.
  4. Log in to your MathWorks account. 
  5. Select Enter an Activation Key for a license not listed.
  6. Copy and paste the Acitvation Key from the license file you downloaded. 
  7. Click Next, then Confirm.
