Why am I getting an error 668: "maximum number of licensed end user redesignations" during activation?:

When I try to activate, I get the following error message:

ERROR: Error 668
This license has reached the maximum number of licensed end user redesignations (transfers) allowed. Contact the Customer Service Team for more information.

What should I do to activate?

This error will occur if attempting to activate when you're not a Licensed End User on the license.

If you are a License Administrator, you can change the User associated with a license in the License Center  of your MathWorks Account.

• Log in to your MathWorks Account
• Navigate to the License Center
• Click on the License Number
• Switch to the 'Manage Users' tab
• To add a User, click on the button that reads 'Add User'
• To remove a User, click on the 'X' icon under Remove User

If you are associated with a license, you can find contact info for your License Administrator in the License Center:1. Go to

To clarify: under the Terms of Use, you may only change ("redesignate") the Named User of a license a limited number of times per year. You will receive this error if you try to change more often than is permitted.
