YES, the Olympus RS-25 Foot Pedal will work on a PC running Windows 7 but there’s a catch.  There are two types of Windows 7 Operating Systems, there’s a 32bit version and a 64bit version.

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.
