Can someone please help with the script below. The ExistKey check always says not installed and then registers the .dll again ? Below is the Code and below that the Regkey dumped to text. Or is there a better simpler way to check for a registered .dll. The users do not have admin rights.

thanks,
Mark

code:
Select
		Case	@PRODUCTTYPE = "Windows XP Professional"
		$ReturnCode = ExistKey("HKEY_CLASSES_ROOT\CLSID\{04F47D98-3495-4634-B195-AAEBB9DB5DD2}\InprocServer32=\\gtb1\netlogon\tqcrunas.dll")
			If $ReturnCode = 0
				? "XP TQCRunAs Installed...."
			Else
				? "XP TQCRunAs Not Installed...."
				Shell "TqcRunas -f \\GTB1\netlogon\registerdll.tqc "
				
			EndIf
EndSelect
