As I attempt to activate my license, I reach the "Provide user name" step and find that my username is correct but I get an error saying that the login name I entered is not valid for activation. It recommends that I use the default value which is exactly what is in the Login Name box. So what can I do about this?

Hi Joe,
When installing and/or activating MATLAB, the MathWorks Installer and/or Activation Client will attempt to pull the username of the user installing MATLAB to activate. If the username was changed or the username pulled is incorrect, the username in the license file will not match the username of the MATLAB user, and MATLAB will provide a License Manager Error -9.
To resolve, verify the Host ID of the machine, and the username of the MATLAB user for Individual licenses, then reactivate MATLAB
