Why is my site trying to download the 32-bit version of aspnet_filter.dll, even if the enable32BitAppOnWin64 parameter is set to False?

Question

I developed the ASP.NET MVC web application on Windows XP and Visual Studio 2008 (using the Visual Studio web server). I recently installed Windows 7, the 64-bit version of Ultimate, IIS 7.5, and ported my application using appcmd.

If I set a flag enable32BitAppOnWin64 == falsein my application pool, my application works fine. As soon as I set it to true (since I want it to run on the 64-bit version), it throws this exception:

Screen Snapshot Error

HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v2.0.50727\\aspnet_filter.dll" failed

If I go over and remove all ISAPI filters, but leave ASP.Net_2.0.50727-64this error will disappear.

How to resolve this?

It seems that Handler Mapping preConditionsfor your site is a bit messed up. In the IIS MMC, go to the site and open the handler mapping function. In the Actions panel on the right, click the Restore Parent link.

It just happened with the deployment of the project. Changing the application pool for the website did the trick. Answer found on Rick Straggle web blog
