IIS 8.5 throwing 404.3 errors for ASPX pages

Question

I just installed IIS 8.5 on Windows 8.1. I installed it after installing Visual Studio 12 and the 4.5 version of the .NET framework. I created a new site and now I am getting this error:

HTTP Error 404.3 - Not found

The page you are requesting cannot be served because of the extension configuration.

I have seen posts here and elsewhere regarding this error and none of the fixes have worked. I have tried running aspnet_regiis.exe - the correct 64 bit version. I have also installed all the ASP.NET development tools, including the .BET 4.5 Extensibility feature. Still I am getting this error. I haven't found a post yet with a fix I have not tried.

Has anyone fixed this issue a different way?

Answer 1

I know that this question is old but I've managed to solve this issue on Windows Server 2012 without reinstalling anything, so just in case I leave my solution for future reference:

I just went to 'Add roles and features' and in the Features part I checked 'HTTP activation' on '.Net Framework 4.5 Features->WCF Services'.
