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

Dear Readers
if you get the error

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

Here is the solution 
Get a command prompt in administrator mode and go to C:\Windows\Microsoft .NET\FrameWork64\
and run aspnet_regiis -r. This will re-register the right libraries. It has happened twice already to me.
For other frameworks (32 bit or other versions of .net make sure you go to the correct folder (i.e. Framework/, etc.)

xxxx is the the number which is present with the folder name so i suggest you guys to check the folder name in your directory

If "run aspnet_regiis -r" is not working and if you get the error run is not recognized command then just type " aspnet_regiis -r" it will run fine

Reason of problem
Your frame work has been change may be you have install the lower version on the higher version or may be because of any reason you have register another version in your IIS, in my cas…
