The auto-detected driver was not correct so I downloaded the 64 bit from http://www.ftdichip.com/Drivers/VCP.htm
and manually directed the hardware configuration to this (extracted) download. It indicated no success.
I believe the pad might have been ordered several years ago, so I also attempted to run this workaround for my 64 bit Windows system:
Through Step3 (removing previous installs) appeared successful. I ran it several times, as recommended, to be sure. It was gone from the hardware list. When I reattach the pad, even if I disconnect the internet to assure no automated driver location, and manually direct the install to the downloaded 64 driver, it is unsuccessful.
I saw the forum posts where this process fails after driver installation and requires reboot, but this is failing to load the appropriate driver. I also tried it on a Windows 32 system with appropriate driver downloaded with the same negative result.
