title: Fortify SCA 4.21's add-in not getting detected by VS2013
body: <p>When installing Fortify SCA 4.21, I can't seem to have it integrate with Visual Studio 2013 (Update 5).  I tried with installing the VS2013 Scan and  Remidiation plugin separately, and with the "VS2013 Plugin complete".  But it doesn't seem to get picked up by VS2013.  </p>
  
  <p>Does anyone know if and where the .addin file is created?</p>
