SAPGUI scripting notification problem

To run vbs files outside SAP to do SAP automation.

I activated scripting via RZ11 "sapgui/user_scripting".

When running a script I receive a notification, when confirming this notification the script runs.

With parameter "sapgui/user_scripting_force_notification" this notification should be hidden.

My current SAP system doen't know this parameter.

I need to set this one; does anyone know how to do this???

Regards...
