You are both right. <smile/> Patching should work if you use the same tool to create the target MSI that you used to create the original MSI *and* that tool supports creating new MSIs such that patching works.
For the same reason, we do not recommend switching versions of WiX when creating the target MSI. Patching is very finicky. It needs the original and target to match appropriately. Changing versions of tools (or switching tools entirely!) when creating those adds variables most tools don't want to debug. <smile/> On Thu, Feb 16, 2012 at 6:01 AM, Christopher Painter <chr...@iswix.com>wrote: > Funny, I also remember them writing a blog talking about how you could use > WiX to author patches for installers that weren't authored in WiX. > > > > http://blogs.msdn.com/b/pmarcu/archive/2008/05/30/patching-something-you-did > nt-build-with-wix-using-wix-.aspx<http://blogs.msdn.com/b/pmarcu/archive/2008/05/30/patching-something-you-didnt-build-with-wix-using-wix-.aspx> > > > Otherwise I agree with you.
