Patch can not be uninstalled
Updated: 22 May 2010 | 1 comment
I created a patch and indicated that it should be uninstallable. I know that option was set because I checked it in Orca.
Even so, after I install the patch I am unable to uninstall it. When I click on the update in Control Panel it does not allow me to uninstall it (though I can uninstall other patches).
I did read Windows Installer MSDN article which indicated that any additions to any one of a set of Tables (~35) would also prevent the patch from being uninstallable. However when I reviewed these tables in Orca (by opening the original msi and then applying the patch) I do not see new (but I do see changed) entries in the listed tables.
Is there any straight-forward way to determine the reason why the patch cannot be uninstalled?

Have you looked in the help file MSI.CHM?
The topic "Uninstallable Patches" gives a very comprehensive list of scenarios where patches will become uninstallable.
If this is insufficient, it may be worth trying a modified patch file that does not make any changes to the notified tables and see if that makes a difference to the uninstallability
