The problem is that you don't have a 64-bit ACE provider installed on the system. Apparently, the target system only has the 32-bit version installed, probably from a 32-bit installation of Office.
You can get the 64-bit version of ACE from
here[
^]. This will have to be installed on the system at the time you install your app on it.
You may as well pick up both the 32-bit and 64-bit ACE installers since your application may run into a system where Office isn't installed at all and will still need to install the correct ACE provider for your application, depending on the system architecture, either 32- or 64-bit.
