Working Around Architecture Mismatch Errors When Using Microsoft Access

From time to time, our customers ask us what their options are when their attempt to use an Access database as their application's back end fails with:

[Microsoft][ODBC Driver Manager]The specified DSN contains an architecture mismatch between the Driver and Application

The cause of the problem is the architecture of the driver used to connect to Access is different to that of their application, i.e. they are attempting to use a 64-bit Access driver with 32-bit application.
