title: IIS 8.5 throwing 404.3 errors for ASPX pages
body: <p>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:</p>
  
  <p>HTTP Error 404.3 - Not found</p>
  
  <p>The page you are requesting cannot be served because of the extension configuration. </p>
  
  <p>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.</p>
  
  <p>Has anyone fixed this issue a different way?</p>
