title: Windows 7 Environment Variable to C:\Windows\Microsoft.NET\Framework64\v4.0.30319
body: <p>I need to create a batch file that run MSBuild.exe</p>
  
  <p>I assumed that I could just call MSBuild, but when I do it does know that program.</p>
  
  <p>MSBuild.exe lives in "C:\Windows\Microsoft.NET\Framework64\v4.0.30319".  But I would rather not hard code that value.</p>
  
  <p>Is there an environment variable in Windows 7 that will point to that location?</p>
