Abstract
The present invention provides a method for unlocking software programs which have been locked to a particular disk by the method described in U.S. Pat. No. 5,327,563. This unlocking method determines if a software program has been moved to a new location since it was originally written to a magnetic disk. In addition this method determines if the program has been executed more than a preset number of times and deciphers the software program if deciphering is authorized.
