title: Visual Studio 2012 Architecture Explorer
body: <p>I can't find anything of the sort, but I'm using Visual Studio 2012 Ultimate and trying to access the Architecture Explorer. When I select it from the View menu I get a quick (&lt; 1 second) mouse loading icon then nothing happens. </p>
  
  <p>No error, no action.</p>
  
  <p>Same happens when I attempt to generate a dependency graph for the solution, no error message is given.</p>
  
  <p>I'm think I must have missed a step somewhere, is there an add-in that is required for this to work?</p>
  
  <p>I've tried re-downloading and reinstalling twice now but to no avail. Everything else works perfectly.</p>
