Several programs can share the same com.adobe.versioncue.controller.link.jar file, but when these programs are uninstalled or changed, sometimes "orphaned" (invalid) JAR registry entries are left behind. Basically, what this means is that while the actual file path may have changed, its incorrect former location is still recorded in the Windows registry. When Windows tries looking up these incorrect file references (file locations on your PC), com.adobe.versioncue.controller.link.jar errors can occur.
