Stand-alone installations:

Stand-alone installations of MATLAB will need to be reactivated with your UMBC MathWorks account once per year. If your MATLAB installation is deactivated and you can't open it, use the MATLAB Activation utility (search for Activate MATLAB in the Windows Start Menu or find it in the Applications folder in Mac). To reactivate a stand-alone install of MATLAB, please follow the instructions below:

1. Open MATLAB.

2. Go to the Help Menu and then select Licensing.

3. Click on Update Current Licenses, select the expired license and then click update (if you don't see Update Current Licenses, select Activate Software and then select Activate using Internet).

4. Restart MATLAB for it to recognize the updated license.

Network license installations:

Network license installations of MATLAB automatically remain active via our central license server. If you receive licensing related errors on your network license installation of MATLAB, please make sure you are either connected to the campus network or the UMBC VPN.
