The solution is applicable to 32-bit machine.

To successfully use the ACE driver for 64-bit machine there are few things which I would like to clarify.

1. If you want to use 64-bit driver first go ahead and uninstall the 32-bit driver from the system/server.

2. After cleaning your 32-bit driver, you must download and install the 64-bit ACE driver.

There are not much changes with respect to solutions for 64-bit but confusion comes because either one of the server or machine of office suite we are using is 32-bit.

Secondly the installation of 64-bit driver on the machine with 32-bit driver always create a problem on the same machine.

I have a 64-bit machine but my office suite is 32-bit so I have not tested this.
