Do you have libgda, and mdb-tools (http://mdbtools.sourceforge.net/) installed?
Our OLEDB ADO.NET implementation links to libgda and uses its configured providers. Also see the FAQ to know the limitations of mdbtools ( http://mdbtools.sourceforge.net/faq.html), being the most important that it gives readonly access to mdb files. It is well advised to migrate your data to some *real* database, like PostgreSQL, instead of keeping it in a undocumented and limited file format.
