Hi Jerry,
through the licensing portal, in the event that you have active maintenance, it is possible to remotely deactivate the license on a computer that we do not have at hand or that has had hardware or other problems. When maintenance is NOT active, you can always transfer the license but you must physically release it from the currently licensed computer and activate it on the new machine. Only in this situation do you need an internet connection, so that the process can be registered on the license server. I hope I have been clear.
Regards,
Francesco
