Our software installer install firebird if it is not present on the system and, as we are pursuing Win certificate the uninstaller should remove it but, we want to make sure that even if it was the installer that put it there, if any new software is using it now with a new database, we would not remove it (Firebird).

The question is: Is it possible to query the server and ask what are the databases running on it? This is it so that we can decide, automatically if we can remove the database or not.

A few extra info: Our installer is Innosetup and it does a good job already - we just trying to make it smarter because of the "Developed by" or "Compatible with" windows logo.
