I just changed dev machines and I'm loading up a project I was working on that used StyleCop 4.7. I've installed 4.7 on the new machine and gotten all my source and when I compile I get this:

"An exception occurred while loading one of hte StyleCop add-ins: System.IO.FileNotFoundException, Could not load file or assembly 'System.Web.Mvc, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

The project is an MVC 3 project.

I can't find any reference anywhere to System.Web.Mvc Any ideas what this is?
