I have setups created by WIX.
I want to prepare patch installer to install/update the files that have been changed in the newer version.
I tried to create patch using WIX code, but was not successful. I also googled about msimsp.exe command but was not able to understand it properly.
Can someone post the example/source code on how can I achieve this?
You can try to use my instruction: WiX patching.
I was able to create patch this way.
If you have more questions, I’ll try to answer them.
