This class requires the Microsoft Access Database Engine to work. The download is available from Microsoft under the name "Microsoft Access Database Engine 2010 Redistributable", available in both 32-bit (x86) and 64-bit (x64) versions.
By default, the redistributable package will only install if it is the same as the current version of Microsoft Office installed in the machine (i.e. ACE 32-bit can not be installed with 64-bit office and vice-versa). To overcome this limitation and install both versions of the ACE drivers, specify /passive as a command line argument when installing the packages.
