I have an .msi that was created using InstallShield 2008. and now I need to use WIX to create a patch. Is this possible using Wix directly or do I need to convery my installshield .ism source to a Wix project
A:
You can create patches using the WiX toolset as long as you have the base MSI and the updated MSI. See http://blogs.msdn.com/pmarcu/archive/2008/05/30/Patching-something-you-didnt-build-with-WiX-using-WiX-.aspx for more information.
