Title:
SECURE ELECTRONIC SOFTWARE PACKAGING USING SETUP-EXTERNAL UNLOCKING MODULE
Document Type and Number:
WIPO Patent Application WO1999062017
Kind Code:
A9
Abstract:
The present invention, generally speaking, provides for secure electronic software packaging using a setup-external unlocking module. A trial dynamic link library (DLL) reads a secondary license file if present, and learns therefrom whether an unlocking DLL is available. If so, the trial DLL loads the unlocking DLL. If no unlocking DLL is available, the trial DLL reads the primary license file, and controls execution of the software according to the information in the primary license file. The unlocking DLL may include an electronic commerce module.
