Yeah, that looks like a version of .NET that pre-dates Version being made comparable, which probably means you're not getting the MSBuild installed with VS.

Check out "where MSBuild" or %MSBUILD% to see if there's something obvious overriding it, and use the MSBUILD variable to override it yourself if necessary.

Good luck! Would love to hear if you find an approach that doesn't involve just setting up a whole machine!
