Thanks Guys. So basically any change that I make during the patch is not going to be executed during patch uninstallation. I was thinking if I can set a property during patch uninstallation.

Subject: Re: [WiX-users] Question regarding the behaviour of custom actions during patch uninstall I believe so. Custom action are in MSI database which is transformed before the install/uninstall (really repair in the case of the patch) starts running custom actions. So during patch install you get patched actions executing. During uninstall you get unpatched action or no action executing because that is the state of the database before it was transformed by the patch. Now it got transformed back and it lost added custom actions. -----Original Message----- From: Anurag Pahwa [mailto:apa...@microsoft.com] Sent: Tuesday, February 09, 2010 4:37 PM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Question regarding the behaviour of custom actions during patch uninstall Hi, I've scenario where I've added a couple of custom actions as part of the patch and sequenced them in during install as well as the uninstall. Now during patch install the custom actions are executed properly but during patch uninstall none of the patched custom actions are executed. Is this by design?
