It appears that the MATLAB installation on your Windows computer has been linked to an individual license that ties the license to a specific user on your computer. If this is the case, you won't be able to access the license using a different user. If you wish to access the license on a machine with any user, you need to get a Designated Computer License for MATLAB.
