title: "Error: One or more projects in the solution were not loaded correctly" particularly for Windows7
body: <p>I am trying to open a Project/Solution in VS 2010. I was able to open the same code successfully in Windows XP, where it gave a dialogue "Temporarily Work Uncontrolled", and on clicking Yes the code loaded and worked fine. But in Windows 7 when I try to open same code it gives me the error:</p>
  
  <blockquote>
    <p>"One or more projects in the solution were not loaded correctly"</p>
  </blockquote>
  
  <p>and no project files are loaded in solution explorer.</p>
