FYI: If you are running a 64-bit OS, there is no 64-bit Jet 4.0 driver. You need to configure your application pool to run 32-bit.
I struggled with this error for a couple hours before I found this:

Hi,
Thank you for providing this useful information, for other 32-bit driver, you can also try running them on Wow64 in similar way.
