You would need to create an installer with appropriate tables, such as
Dialog, Control and ControlEvent. It may need user interaction so it
would need to be interactive. 

A standalone test would work too. The point is that I'm not convinced
that we don't need to check the msidbDialogAttributesModal attribute.
