Abstract

Method and system for detecting attempted invocation of execution of any application program by searching each application's header file information for an operating system kernel Dynamically Linked Library DLL reference and replacing the operating system kernel DLL reference with a intercept routine DLL reference. The intercept routine will be invoked upon attempted invocation of the application program and contains management logic for any desired software asset management function for execution prior to permitting invocation and execution of the application program.
