Abstract

A computer-based self-launching system associated with a software program or other digital information is provided for distributing the software program or other digital information to a potential purchaser. The self-launching system is attached to a software program or other digital information and includes the ability to launch itself when a user selects the software program or other digital information. Upon launching itself, the system unlocks the software program or other digital information in response to a purchase request.
