It may be a problem with a 'new' WiX patching, as opposed to WiX patching that is just a wrapper around the legacy PatchWiz.dll. I think I encountered similar issues in the past and decided to stick with PatchWiz.dll for the time being. Except for bugs in Windows XP versions (and these seem to be patch application, or MSPatcha.dll versions for XP, bugs) my experience is that PatchWiz.dll processes small binary differences well enough to be useful.

Subject: Re: [WiX-users] How does patching decide which files to include in msp? Thanks for the reply. Just to be clear this is not an install time issue in which certain files are not updated because their modification times have changed. I am able to extract the .msp file immediately after creation and confirm that files are not included that I wish to include. Applying the patch in Orca shows the same issues. It looks like this is occurring at the patch assembly level. -----Original Message----- From: Tony Juricic [mailto:tjuri...@tradestation.com] Sent: Friday, September 17, 2010 3:28 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] How does patching decide which files to include in msp? These are not WiX rules but MSI rules and are documented on MSDN site, somewhere in install patching section. -----Original Message----- From: Travis Gaff [mailto:tra...@pc-doctor.com] Sent: Thursday, September 16, 2010 12:48 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] How does patching decide which files to include in msp? Hello WiX users, I am trying to construct a .msp file to patch a several hundred file installation. However I am finding that a large number of files are not ending up in the final .msp file. Right now I suspect many of these are due to both the new and the old version of the file having the same version number; we're fixing this. However I have some files that do not have a version number and do have an internal change but are not in the msp. They appear to have little difference from most of the other files, they're all added with individual components to a .wxs by our build system. How does WiX decide which files to include in a patch using the pyro/torch method? By comparing several files I suspect it does the following: 1) if a file has a version number, check it, if same version skip file 2) if file doesn't have version number but there is a size difference: patch it? (I haven't verified this) 3) if no version number AND file is same size: diff the file or use creation date? What rules does WiX use to determine which files should be included in the msp? Background: All components are in 2 features. The 2nd feature is a sub-feature of the first and right now I am not even looking at its 2 shortcuts. The *patch.wxs file includes: <ComponentRef Id='co_mainui.exe' /> (a component of the main feature) <PropertyRef Id='ProductVersion'/> (to update the ARP program version) The patch is generated using .wixpdb files with torch and pyro: candle patch.wxs -dcodepage=1252 -ext WiXUtilExtension -dtop_projects_dir=C:\projects light -o out.wixmsp -cultures:en-us -ext WixUIExtension patch.wixobj -ext WiXNetFxExtension -ext WiXUtilExtension -dtop_projects_dir=C:\projects torch -t patch -p -pedantic -xi build1.wixpdb build2.wixpdb -out out.mst pyro out.wixmsp -out out.msp -t patch out1.mst I am using 3.5.1916.0, however I had similar issues in 3.0. Thank you for any help you can offer.
