compile errors on installing/starting Orchard

I just installed a clean new version of Orchard (1.4.1) via Web Matrix, but I keep having these compilation errors stating:

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper<dynamic>' does not contain a definition for 'Raw' and no extension method 'Raw' accepting a first argument of type 'System.Web.Mvc.HtmlHelper<dynamic>' could be found (are you missing a using directive or an assembly reference?)

I can't find any concise explanation on Google.

Have I forgotten to install something?

Any feedback is very appreciated.

Kind regards,

Is the app pool configured for ASP.NET 4.0 Integrated mode?

The site is configured for ASP.NET 4.0 Integrated mode.

It runs on my shared host but I cannot get it to run stable on my local (Vista) pc.

And you're running it from WebMatrix?
