Connection at design time not working

I'm trying to use the Security System in my application. I looked at the example but this is already not working at design time. You write in your documentation that if you drop a SecurityManager and a FormPolicy on the form you can use this with a double click to manage the security (of course all connections to the dataset are implemented - like in your example). This is not working - also not in your example! If I doubleclick the SecurityManager I get:
"C:\Program Files (x86)\Embarcadero\Studio\23.0\bin\Data\security.mdb is no valid path."
At run time it is working because I set the path (like in your example). What's to do to make this working also at design time with my path for the dataset?
