HTTP Error 500.0 - Internal Server Error Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed

HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed


Problem :
If you install .Net framework in machine that already contains .Net Framework 4 , it caused the error

Solution :
Get a command prompt in administrator mode and go to 
C:\Windows\Microsoft .NET\FrameWork64\v4.xxx(version number )
and run 
aspnet_regiis -r. 


It will re-register the right libraries.
For any other kinds of framework locate the exact folder location of framework 4 , fine the file name asnet_regiis and run the command as above .
Now it solves the issue  hope if will work for you.

    Hi All,

    I got this error, before you do any above stuff, just try below

    1. Click on your computer icon in IIS

    2. On right side, you see ISAPI filters – Click

    3. Pick up the Filter name ASP.Net_4.0_64bit and its path MIGHT HAVE AN EXTRA \ IN THE PATH,

    SO UNABLE TO LOAD THIS DLL,

    %windir%\Microsoft.NET\Framework64\\v4.0.30319\aspnet_filter.dll

    4. restart IIS – should resolve the error.

    thanks
