we have to uninstall the 4.5 which comes under the Server roles not features. I am also attaching screen for the reference.

For this open the Server manager -> Dashboard -> 2) Roles and Features and follow the following steps which are mentioned in screenshots.

Note: I am showing you how to Add Roles and Features wizard (install new features/roles) but if you want to uninstall/remove (uninstall new features/roles) then you have to click on “Start the Remove Roles and Features Wizard”. Please make sure that, first we have to install IIS and then .NET framework.

Select the server

<img src="https://i.stack.imgur.com/JdDqt.png" alt="enter image description here">

You have to check ASP.NET 3.5 and ASP.NET 4.5 (based on requirement) options for register the .NET framework with IIS.

<img src="https://i.stack.imgur.com/oABh7.png" alt="enter image description here">

To install any features/roles, we have to check that option which we want to install. For uninstall any features/roles you have to uncheck it.

Please find the reference links below.

I had tried this once before on a Server Core Installation with the GUI installed. Similar to what the original poster saw I was Dropped into a Black Screen. not sure if he saw the same thing, but you can recover from this by reinstalling the GUI instead of starting a clean install. On 2012, Uninstall .NET 4.5 as a last resort, and if you completey remove all .net, don't be surprised to see the Command prompt on reboot. For help on GUI re installation see:

I am getting MIME is not registered error when I run WCF service. I used this <a href="http://3water.wordpress.com/2012/09/05/host-wcf-in-iis8-windows-server-2012/">link</a> to resolve this issue. After that I started getting another error which asked me to register the ASP.NET framework with IIS. So I used "aspnet_regiis" command for it but it shows me following error.

I tried to install/uninstall ASP.Net 4.5 from the server. But after doing that, my server was not started again and it always show the black screen. So I have to install the WS 2012 again. Can somebody explain me how to register ASP.NET with IIS again on WS 2012?
