How to clear the error “ExtensionlessUrlHandler-Integrated-4.0″ has a bad module “ManagedPipelineHandler” in its module list

Monday, December 22nd, 2014

Started with another MVC4 web application that requires Https today and got this error when I tried to browsed the app from local IIS 7:

ExtensionlessUrlHandler-Integrated-4.0″ has a bad module “ManagedPipelineHandler” in its module list

Thanks to this post at http://www.brandonmartinez.com/2014/07/02/resolve-an-http-error-500-21-in-iis/ and followed the instruction to run
regiis, I was able to clear this error and successfully browsed to the local site’s landing page. Here were what I went through (I was on a Win7 x64 bit machine):

  1. All Programs -> Visual Studio 2012 -> Visual Studio Tools
  2. Right clicked on the “Developer Command Prompt for VS2012″ selected “Run as administrator“; this was a must or the next step would not be executed.
  3. Went to directory at C:\Windows\Microsoft.NET\Framework64\v4.0.30319 and ran this command line: aspnet_regiis.exe -i
  4. The whole thing should look like this after done:
    C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -i
    Microsoft (R) ASP.NET RegIIS version 4.0.30319.18408
    Administration utility to install and uninstall ASP.NET on the local machine.
    Copyright (C) Microsoft Corporation.  All rights reserved.
    Start installing ASP.NET (4.0.30319.18408).
    ....
    Finished installing ASP.NET (4.0.30319.18408).
    
  5. After that, I went back to IIS and re-started the website (which was assigned to a port 44300 for https) then browsed to the landing page and now everything looked pretty.
