Hi, While creating the web project I am getting the error "asp.net 4.0 not registered on web server.

I was trying :

aspnet_regiis -i

Start installing ASP.NET (4.0.30319.0).This option is not supported on this version of the operating system.  Administrators should instead install/uninstall ASP.NET 4.5 with IIS8 using the "Turn Windows Features On/Off" dialog,  the Server Manager management tool, or the dism.exe command line tool.  For more details please see http://go.microsoft.com/fwlink/?LinkID=216771.Finished installing ASP.NET (4.0.30319.0).

Kindly help
