Just thought I'd share in case it saves some other folks some time.
If you use a later version of Access as the database for DxDatabook and your business updates to Office 2016, the Microsoft Access driver that allows connection to an '.accdb' database is no longer available. This means DxDatabase will stop working.
The solution we have found is to download the 'Microsoft Access Database Engine 2010 Redistributable' from the Microsoft website and install it. DxDatabase will then continue to work as intended.
There is no need to redefine the ODBC Data Source.
