[wix-users] How do you patch files that is gathered by heat.exe?

[Tyler Gustafson]

Glad to hear it!
You could probably run the commands as project Post-build events if you get fancy. I'm currently working on a powershell script that hunts down all .msi files in a folder tree and creates a patch that goes from any of them to the latest one with the intent of keeping a folder of all released to the wild builds somewhere and then integrating my powershell script into the build process. It's only mostly done at the moment but I can pass along what I have if you are interested.

Thank you very much Tyler. I was able to create a msp file with the change properly affected the installed folder.
It is unfortunate that I have to make a batch file rather than running these on post-build events.
However, I achieved what I wanted and I am extremely grateful.
