SYMPTOMS
After you patching a Windows Installer installation, it is not possible to uninstall the patch. The only workaround is to uninstall and reinstall the program without the patch.



CAUSE
When a package is deployed with a patch installed, the original MSI database is merged with the patch database to create a new "patched" MSI file. This means that removing the patch would involve replacing all changed information in the "patched" package with the original information, and removing any additional information added by the patch.



STATUS
This behavior is by design.
