Problem building VS 2013 solution after upgrading to v9.2
 

I upgraded to V9.2 yesterday and today I found that none of my VS2013 build scripts ran. The error said it was missing Microsoft.Cpp.Default.props. I created a macro that pointed to where it is and retried. Now I'm getting an error on every project that says "The imported project "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120Microsoft.CPP .UpgradeFromVC71.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.". Does anyone have a fix/explanation for this? Thanks in advance!

Most likely, the version declared in the solution file doesn't match the VS/MSBuild version it actually requires. See here for more details:

Thanks for replying but I don't think that's the issue. This is a solution we build every night without any problems. The only thing that changed was upgrading Visual Build from version 8.7 to 9.2.

v9 is more precise about matching the declared version in the solution/project with the devenv/msbuild version (it could have matched a compatible version by luck in the past when the declared version wasn't actually correct), and that's the only relevant change to the Make VS* actions.
