Yes, the Olympus RS25 foot pedal will work on a computer with a 64bit operating system but there’s a catch.
The RS-25 Foot Pedal with the USB Adapter will only work on the 32bit version. In order to use the Olympus RS-25 on the 64bit version, you must connect it using the Serial Adapter.
Note: Both adapters were included with the Olympus RS-25 foot pedal.
