.NET

I installed .Net 1.1 on a Windows Server 2008 (which already had .NET 4 installed). Afterwards, I started getting the following error:

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

I have tried running aspnet_regiis without success. I have also tried the suggestions by Rick Strahl but to no avail.

I have also removed .NET 4.0.30319 using the cleanup tool. When I reinstalled it, The error was still there. I have already removed 1.1 but still i get that error. Please help.
