What I mean is that in my experience, for DocuWare to be abel to read data from an Access database, you need to set up Access to have a user name and password. All of DocuWare's ODBC connections request a user name and password.
In any event, this issue is the subject of a support request, and it should be handled through that and not in the forum at this time.
I wil make this comment. In my testing with 7, I used an Access database to configure a 64 bit ODBC connection and it was successful. So let's see where the investigation goes, however as I said Access typically must be secured.
