  1. I just wrote a blog post addressing this. You could install ASP.NET MVC on your server OR you can follow the steps here.

    EDIT: (by jcolebrand) I went through this link, then had the same issue as Victor below, so I suggest you also add these:

    * Microsoft.Web.Infrastructure * System.Web.Razor * System.Web.WebPages.Deployment * System.Web.WebPages.Razor
