It sounds like the Delphi error "List index is out of bounds (0)" which is thrown when some application code accesses the first member of a Tstrings object but the list is empty and the application code has not provided error handling for it. It is not a Firebird error.

It sounds as though you need to contact the tech support people for your software and find out whether their application (or their installer program) is expected to run successfully on Vista. Firebird 1.5 predated Vista, so chances are the software and the installer did, too.
