title: Problem in Opening Word 2010 using Visual Studio 2010?
body: <p>I have been trying to open a Word document using C# in VS2010. But I have been successful so far. I have tried searching for answers but all in vain. In the reference section, I cannot see the Microsoft Word office library (any version) in the COM tab. I added the Microsoft.Office.Interop.Word. version 14 from the .Net tab, but still i get the same exception:</p>
  
  <blockquote>
    <p>An unhandled exception of type
    'System.Runtime.InteropServices.COMException'
    occurred in mscorlib.dll</p>
  </blockquote>
  
  <p>Additional information: Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).</p>
