I do not know if I have the solution but I would expect to see
Code:
connectionString="Provider=Microsoft.ACE.OLEDB.12.0 ...
In your App.Config file.
I just used the wizard to build a connection string and that is the driver it used. I have Access 2010 (Version 14) installed on this machine and a paid version of Visual Studio. I did not download any drivers. If it is a Windows Desktop App you built I would think the driver would be included with your publication and it would be version 12.
Did you check the Settings under your Project's Properties to see if the App.config matches the Settings file?
