I don't believe that Medion has ever written any Windows Vista drivers for their scanners. But you can check here: http://www.medion.co.uk/service/?dri...rs_updates.htm
Note: I just looked and they only have drivers posted for Win 2000/Win 98/Win 98SE/Win ME/Win XP
No Vista drivers are posted. I really doubt Medion will ever write drivers for Vista for their scanners. I don't know why... maybe they can't because of hardware limitations.
