The difference may be in the computers used. Since all Kodak cameras use SD cards, the quickest solution would be to purchase an inexpensive SD card reader, which usually run less than $5.00.
The take the SD card out of the camera and put it into the card reader. The computers will recognize the card reader as an external drive and you are all set.
As Kodak cameras age, it is not uncommon for them to become somewhat cranky about downloading. Using a card reader also saves on camera "wear and tear" and battery usage.
