title: Missing ".NETFramework" directory in "Program Files" directory
body: <p>I have a 64bit Windows 7 development machine and I have the following directories:</p>
  
  <pre><code>C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework
  C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v3.5
  C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0
  C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5
  C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.1
  </code></pre>
  
  <p>But for the 64bit <code>Program Files</code> directory, I only have:</p>
  
  <pre><code>C:\Program Files\Reference Assemblies\Microsoft\Framework
  C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0
  C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5
  </code></pre>
  
  <p>So why <code>C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework</code> is missing? Am I forgetting to install something?</p>
