As others, I signed the online Visio to draw several ERD from several Access databases; I already have an LucidChart account, but they do not have a reverse engineering for mdb/accdb files.
So, I tryed the ODBC driver, selected the Access driver mdb/accdb, selected tables and... nothing.
Error in all tables: Error! Cannot extract column definition for the table/view 'Eventos'. The definition is not available or you may not have sufficient privileges. Please check with your database administrator.
The accdb is not protected...
