почему мой код не работает со старыми драйверами доступа?

Предполагается, что этот фрагмент кода возвращает имена таблиц в базе данных и работает для доступа к базам данных, сохраненным с расширениями * .accdb (т. Е. Microsoft Driver), которые, как я предполагаю, являются одними из последних драйверов, но я не могу понять, почему не работает драйвер с Microsoft Access (* .mdb). Кто-нибудь может сказать мне, почему это происходит?

это пример вывода, когда DSN создается с последним драйвером.

и это пример вывода, когда я создаю DSN с более ранними драйверами
