I'm not sure what you mean by your question, but there are actually two different database objects that can be used. In Access 97, the DEFAULT reference is DAO, and in Access 2K and above the default is ADO.
You have to check the references to see which one is currently installed. You can install both objects, but MAKE SURE in your declarations you explicitely specify which datase object you are using.
Not:
Dim db as Database
Instead,
Dim db as ADODB.Database '(for ADO objects)
or
Dim db as DAO.Database '(for DAO objects)
