Abstract
A method and apparatus for providing, maintaining and upgrading the software lock of a microprocessor. When a processor upgrade occurs, software that was serialized to the previously installed processor detects that it is running on an unauthorized processor. The software initiates a reauthorization process based on a reauthorization use profile. The temporary re-enabling of the software is allowed if the authorization service is not available.
