You need to change the username in the mathworks license center and download the license file again.

LicenseCenter

Where in the license center can this be changed?

Can someone please write the steps to correcting this in the form? When you post a link to a solution the link may change.

You need to deactivate the license and reactivate it with the correct user name. The details of finding the appropriate files and the steps to take in various cases get to be a bit long, and if we posted them here then we would have to keep updating them here as well as the other locations.

You can search for the relevant information using

which will continue to work even if the exact posting numbers move.
