QuickStart Tutorials installation fails

I have installed IIS and APS.NET 2.0 manually followed by IISRESET according to the Configuration Details document but the setup insists on attempting to reinstall ASP.NET 2.0 and failing.

No instance of Visual Studio of any version has ever been installed prior to installing VS 2005.
I am using Windows 2000 Pro SP4.

Any suggestions?

Thanks
Craig
