Answer 1

You need to download the Microsoft Access Database Engine 2010 Redistributable from the Microsoft download center. A 32bit driver and 64bit driver are both available. What works?

If you have a 64bit server with no Office installation then install the 64bit driver.

If you have a 64bit server with 32bit office installation then install the 32bit driver*.

If you have a 32bit server with no Office installation then install the 32bit driver.

If you have a 32bit server with 32bit Office installation then install the 32bit driver.

*If you are trying to install the 32bit drivers on a 64bit machine then the installer will complain and fail. However the install has an override flag if you install it via the command line (cmd.exe) with administrator privileges.
