I have ASP.NET web services and ASP.NET web application running on .NET framework 1.1 hosted on a Windows Server 2003 IIS 6 machine.
I have a new application requiring on .NET 4. Until I installed ASP.NET framework 4.0, it was working fine.
Now my .NET framework 1.1 applications have failed.
How can you configure an IIS 6 instance to run 2+ applications each respectively requiring different versions of the .NET framework?
