  <p>I tried to do the fix <a href="http://blog.williamhilsum.com/2011/03/error-0x80070643-installing-aspnet-mvc.html">here</a> but it is not working for me.</p>

  <p>I get a bit further than what you see in the above screenshot as it seems to hit what I think is nuget and then instantly rollbacks. It happens so fast I can't get a good look.</p>
  
  <p>I do have Visual Studios 2010 SP1 installed.</p>
