Why do I get a "Deactivation Required" message when deactivation isn't required?

Best Answer

This error can occur if the license information on the local machine does not match what is in the activation database. To resolve this issue, reactivate MATLAB to update your activation information. If you do not have activation permissions or the activation key, ask your license administrator to assist you with this process.
If you have just completed a manual activation and are receiving this message, see the following article:
