title: Notorious Visual Studio Error C1902, VS configuration
body: <p>I am getting the notorious "Error C1902: Program database manager mismatch; please check your installation" in my VC++ builds in Visual Studio 2010. My VS will not even build hello world, there is no pdb file even in existence in the folder.</p>
  
  <p>Steps I have tried:</p>
  
  <ul>
  <li><p>cleaning and rebuilding (3 different projects including hello world, about 15 times)</p></li>
  <li><p>removing every single instance of Visual Studio before version 2010 from the computer including all redistributables. There is no copy of mspdb*.dll on my computer anywhere except the latest version (100) in my 2010 directory.</p></li>
  <li><p>Reinstalling 2010. I completely reinstalled VS 2010. No effect.</p></li>
  <li><p>Rebooting my computer. I have spent the afternoon deleting anything that might be remotely related to this bug and rebooting over and over again.</p></li>
  </ul>
