Answer 3

Have you registered the .NET framework with IIS? You need to run the aspnet_regiis.exe utility found at %WindowsDir%\Microsoft.NET\Framework\vx.y.zzzz\. Run it as administrator as follows:

aspnet_regiis.exe -i 

-i : Installs the version of ASP.NET that is associated with Aspnet_regiis.exe and updates the script maps at the IIS metabase root and below. Only the script maps for applications that use an earlier version of ASP.NET are updated. Applications that use a later version are not affected.
