ISAPI filter error message

Problem

You get this error message:

Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed

Solution

1. Click on your computer icon in IIS.
2. On right side, click on ISAPI Filters.

3. Pick up the Filter name ASP.Net_4.0_64bit. There MIGHT BE AN EXTRA \ IN THE PATH, SO WE'RE UNABLE TO LOAD THIS DLL. Remove the extra \ from the path so that it looks like this: %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_filter.dll

4. After applying these changes, restart IIS and the error should be resolved.

Please see these larger images for an example.
