A system and method for providing the ability to repair an installed application program if a resource needed by the application program becomes inadvertently deleted or otherwise unavailable to the application program. Briefly described, the present invention makes possible a system for verifying the existence of a resource needed to support a feature of the application program. The system may respond to a request from the application program to make use of the resource by first verifying the existence of the resource at an expected location. If the resource does not exist at the expected location, rather than returning an error to the application program, the system initiates an installation procedure for restoring the missing resource without interrupting the normal operation of the application program.
