title: Visual Studio crashes when trying to open up
body: <p>I've installed Visual Studio 2013 a few weeks ago. I played around with making some C# applications. But today when I tried to open up Visual Studio, I got the following error message: The operation could not be completed. No such interface supported.</p>
  
  <p>I have tried to run it as administrator, same problem. This is the only version that's installed on my computer. I have Win 7 64 bit. Could anyone help please?</p>
