Sorry, perhaps I didn't explain. We are not using MSBuild directly to create the installation, rather, we are using the VS plugin to enable the Wix projects to be part of the solution that is built by the TFS build. We now have a number of components that need patching from the original msi, this doesn't need to be automated as part of a TFS build.
On the basis that we have never directly used the Wix tools (candle etc.) I have been trying to follow the patch example from the wix helpfile to see if I can use this as a basis for creating the patch... # Build the target layout candle.exe -dVersion=1.0 product.wxs light.exe product.wixobj -out 1.0\product.msi # Build the upgrade layout candle.exe -dVersion=1.1 product.wxs light.exe product.wixobj -out 1.1\product.msi # Create the transform between your products torch.exe -p -xi 1.0\product.wixpdb 1.1\product.wixpdb -out patch\diff.wixmst # Build the patch candle.exe patch.wxs light.exe patch.wixobj -out patch\patch.wixmsp pyro.exe patch\patch.wixmsp -out patch\patch.msp -t RTM patch\diff.wixmst Because we use VS project references (e.g. $(var.projectname.ProjectDir) ) in the wix source file I cannot run candle against our wix file, and it's not a simple thing to alter this as we have 80+ projects in the solution, hence there are a lot of VS references. Additionally, as the builds are automated we don't have the .wixobj files to run light against. We do have the .wixpdb file from the build so I tried running torch to create a transform against 2 copies of this file in 2 different folders (a pretty vain attempt I admit) but as there was no differences when I ran pyro it gave an error. Looking at the example the only differences seemed to be the version number from running candle and the output location from light, but this seems to have been enough for the transform to be different (unless I'm missing something?). My only guess is to try and edit one of the .wixobj files in a similar way, but this doesn't seem to be the right way I should be going about it, which is why, as we have been able to use a VS plugin to create our original msi, I wondered if there was a way of using this to create a patch. Alternatively, is there a better model I could follow than that from the helpfile?

Subject: Re: [WiX-users] Creating a patch with the Visual Studio plugin Unfortunately, we don't have MSBuild Tasks for the patching system, yet. Of course, all the tools will work fine in MSBuild... just need to do a bit more work yourself right now.
