Abstract

A process and system for activating various programs are provided in a personal computer (10), The personal computer (10) is initially provided with a registration shell program (11). A data link (30) is established between the personal computer (10) and a registration computer (12). By providing the registration computer (12) with various information, a potential licensee can register to utilize the main program (16). Once the registration process is complete, a tamperproof overlay program is constructed at the registration computer (12) and transferred to the personal computer (10). The tamperproof overlay includes critical por-tions of the main program (16), without which the main program (16) would not operate and also contains licensee identification and license control data.
