title: using VS2013 but still get "The builds tools for v120 (Platform Toolset = 'v120') cannot be found." error
body: <p>I'm using Visual Studio <strong>2013</strong> on a Windows 7-64 machine and still got the below error.
  I have exactly the same reg key setting under <strong>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild</strong> to my coworker who can compile the solution fine. we are using the same VS2013.</p>
  
  <p>it's weird that my log shows "C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\ <strong>V110</strong> \Microsoft.Cpp.Platform.targets(44,5)", but not <strong>V120</strong>.  anyone knows why?</p>
  
  <p>appreciate any clue and help, been stuck for a few days.</p>
