MATLAB installations using Designated Computer licenses running in regular user accounts cannot update their licenses using the "Update License" feature in the MATLAB Help Menu. Since, with a Designated Computer license, the license file is stored in the MATLAB installation directory, administrative (Mac & Windows) or superuser (Linux) permissions are required to update the license file.
If "Update License" is run from within MATLAB, the updated license file will be generated in the License Center, however it will not be written to the disk of the machine running MATLAB. The license file on the machine running MATLAB can be downloaded from the MathWorks website and updated by someone who has administrative or superuser permissions on the machine in question.
