I am new to Umbraco and I am trying to install v4.0 on XP. I am following the book Installing v3.0 on XP and everythign goes fine until the point I try to launch the setup. At this point it gives me error Could not load file or assembly 'System.Web.Abstractions, Version=3.5.0. Screen shot can be seen here http://img818.imageshack.us/img818/5116/error.gif. Please note that I don’t have any version of Microsoft MVC installed on my PC and that is not mentioned anywhere in the documents as well. So what can be wrong and how can I resolve this problem.

Thanks in advance
