Thank you so much for your advice. I recently bought the Canon 20D used. I didn't even think to ask about it being compatible with my OS. Thanks again. Changing the communication over to PFP was the trick!
In the camera menu, Switch communication to PTP instead of Normal. Will work fine. Bugs in Cannon EOS camera firmware/hardware do not properly handshake with generic MS windows drivers,
Picture Transfer Protocol works without a computer, so in addition to your PC you could also send them directly to a printer for example.
