title: Visual Studio does not see Microsoft Office references
body: <p>My point was to use Microsoft Office libraries, e. g. Microsoft.Office.Interop.PowerPoint. Microsoft Visual Studio Professional 2013 cannot see them between references when I am trying to add them to the project using Search option of Reference Manager. However, they are in the folder among "Program Files (x86)" (C:\Program Files (x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA). I can only add them manually, like browsing and giving their location, not through the search option in "COM" in Reference Manager. </p>
  
  <p><strong>How can it be explained?</strong> </p>
  
  <p>Microsoft Office itself is not running in computer, but I installed these assemblies manually.</p>
