asp.net mvc 4 - aspnet_regiis.exe -ir does not work on windows 8

Question

I am trying to deploy an ASP.NET MVC3 app to my Windows 8 box with IIS8. When I try to route to the site I get the following error:

Pretty much everything I can find on this issue says to run:

aspnet_regiis.exe -ir

When I run this on my Windows 8 box, I get the following message:

Start installing ASP.NET (4.0.30319.17929) without changing existing web 
applications to use this version of ASP.Net.  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

ASP.NET 4.5 is already installed on my system.

My application runs correctly in Visual Studio, but I can not deploy it to save my life. I am completely at a loss on where to go from here. I have tried both integrated and classic pipeline modes for this site as well.

Answer 1

Run the following command, which will install and register ASP.NET 4.5 in IIS:

dism /online /enable-feature /featurename:IIS-ASPNET45 /all
