Take a look at http://msdn.microsoft.com/en-us/library/aa370739%28v=vs.85%29.aspx where it says:
/The Custom Action Patch Uninstall option is not available. There is no method for marking a custom action within a patch package to be run when the patch is uninstalled because the installer does not apply the patch packages being uninstalled. To have a custom action run when a particular patch is uninstalled, the custom action must either be present in the original application or be in a patch for the product that is always applied./ And also, this other thread where someone was having the same problem: http://sourceforge.net/p/wix/mailman/message/27387586/ If you are targeting Windows Vista SP2 or later, then maybe the PatchUninstall property on the custom action would work better. Some more info about it can be found at http://msdn.microsoft.com/en-us/library/bb736308(v=vs.85).aspx. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Custom-Actions-added-with-a-Patch-are-ignored-during-uninstall-tp7598511p7598555.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
