Unable to configure WFServicesReg.exe on Windows 2003 SP2

Hi ALL,

I was trying to configure Workflow support on IIS 6.0 (?) with 'WFServicesReg.exe /c' option and I get the following error message. I tried some help on the internet like re-register 'aspnet_regiis.exe' and running the WFServicesReg.exe again..It didn't work. Nothing helped.

I have dotnet framework 2.0, 3.0., 3.5 and 4.0 installed and IIS shows ASP.NET 2.0 and ASP.NET 4.0
