View Full Version : unable to uninstall a patch with 10.5

12-15-2004, 08:54 PM
I am writing a Quick Patch patching dll files in a current program on a terminal. I am only able to uninstall the patch when the patch is performing an insertion of a new dll, and deletion of an existing dll. When I update (other settings being equal with insertion and deletion) an existing dll with a later version number, it updates it when the patch is run, but this patch can't be uninstalled (ie. in add/remove programs it says underneath this patch "This update cannot be removed"). This (unable to uninstall a patch) only happens when the file to be updated is a dll and ocx. a patch can be uninstalled when it's to update a gif file and a text file. Does anyone know why this happens please?
