Specify whether to automatically generate entries for the MsiPatchOldAssemblyFile and MsiPatchOldAssemblyName tables, which allow a patch package that is running under Windows Installer 3.0 or later to patch an assembly in the global assembly cache (GAC) without making a run-time request for the original installation source. For more information, see "Patching Assemblies in the Global Assembly Cache" in the InstallShield Help Library.
