Why do I see the error "MATLAB cannot verify your license rights over the Internet" when launching MATLAB?

When I attempt to launch MATLAB, I get an error that says:

MATLAB cannot verify your license rights over the Internet.

Activate your software or contact your MATLAB administrator.

How can I fix this issue?

This error occurs when attempting to open an instance of MATLAB configured to use Login Named User with a MathWorks Account that is not linked with this type of license. This means that you are logged in to the local domain account of the person licensed to use MATLAB, but using a MathWorks Account that is not linked to a Login Named User license. This issue is not related to the MathWorks account credentials used to log in, rather the way the license is configured. 

To resolve this issue, check for a license_info.xml in the MATLABROOT/licenses directory and delete the license_info.xml file so that the intended license offering is used when MATLAB is launched. If your license is not currently activated, you will be prompted to reactivate. 

For instructions on activating MATLAB, please refer to the following.
