Help with Visual Studio step

[deramor]

Hello,

My build environment was working fine but then I installed the Visual Studio 2015 build tools and now my VS2019 steps are using a different version of MSBuild.

For now, I've overridden the path to MSBuild in the options tab of those failing steps but I wanted to better understand the problem. I don't want to be forced to forever have to implement this workaround.

My question is, how does Visual Build locate the version of MSBuild? I know it has to do with the solution files from posts I've seen on these forums. All of my solution files are created in VS2019 (and were previously working). If I knew the step's logic, I could look in more places (like registry) that could have been modified erroneously.

Thanks for any input.
