title: VS 2010 Properties Page Fail to Show-COM object that has been separated from its underlying RCW cannot be used
body: <p>I'm using Visual Studio 2010 Ultimate edition, but now it won't show the project properties page. Instead an error message show up saying
  <strong><em>An error occurred trying to load the page.
  COM object that has been separated from its underlying RCW cannot be used.</em></strong></p>
  
  <p>This error has plagued me for a long time. I tried almost everything (uninstall/reinstall/repair/uninstall addins, etc) except reinstall 
  OS. 
  Help me out. Thx a lot!</p>
