IIS settings problem

Question

I have installed IIS on my windows7 but it is some problems with it. I successfully can open html files like (http)://localhost/index.html , but can't open ASP site: (http)://localhost/ProjectList.aspx

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

What the problem? (I have already reinstalled .NET 4.0)

Maybe it is another way to wath my website? Like with the help of Visual Studio 2010?
