" Visual Studio needs to make non-functional changes to this project", when trying to make a CPP project

HI @Tristan.alvarez ,
I found this post where they discuss the exact same error you’re seeing:

It explains that these issues usually come from not having all the required packages and SDKs installed correctly. Each Unreal version expects a specific Visual Studio version.

The recommendations are:

  • Make sure you have the correct MSVC installed for your Unreal version.
  • Uninstall any older Visual Studio versions that might be causing conflicts.
  • Regenerate the project files from the .uproject.

Hope this helps!
