ERROR: Unable to cast COM object of type 'MSScriptControl.ScriptControlClass' to interface type 'MSScriptControl.IScriptControl'

You should check for a 32-bit vs 64-bit issue. The Script Control is only a 32-bit component. You can't have IIS running as 64-bit if you plan on using the Script Control.
