This is an old scanner and I fear you are out of luck. Scanner technology and specs are constantly improving. Rather than release new drivers for old models to make them xp compatible, many companies decided it was a backward step and instead turned out new models with new xp drivers. You can see the logic -- as more people get xp they will have to also buy new hardware with drivers that work with xp. Keeps the manufacturer's happy -- and the PC World shops!
