Abstract
A computer-based system is provided for automatic sales of software programs. The system accesses a software program within a computer database and maintains the software program in a locked state in order to prevent unauthorized duplication of the software program. In response to a request to purchase the software program, the system unlocks a copy of the software program and distributes the unlocked copy. The system records how many copies of the software program have been distributed in response to the purchase requests for billing purposes.
