Making a patch obsolete (MSI 2.x) is an older technique. All currently supported/patched OSs by Microsoft currently sport MSI 3.x or higher, which allows you to use the newer technique referred to as superseding.
They are not the same thing. The "pure WiX patch" method only supports the supersede methodology, not obsolescence. If you can change over to superseding, that would make your life much easier. If, however, you must still support MSI 2.x, you can't. If you must still support obsolescence and you want to use "pure WiX patching" you must post-process the patch to add the additional guids. I didn't have much easy success trying a "quick and dirty" change to the summary information using the installer APIs but I did note that you can use XSLT to transform the patch's wixobj file. This would need to be done before calling Pyro after calling Candle. -----Original Message----- From: shibo [mailto:szheng...@googlemail.com] Sent: Friday, August 14, 2009 2:36 AM To: wix-users@lists.sourceforge.net Subject: Re: [WiX-users] Purely WiX patching - two questions please Blair, >From Wix Help, Patch family attribute Version: Used to populate the sequence column of the MsiPatchSequence table in the final MSP file.
