Basically the problem is that ARTEC have not updated the drivers for the AM12E plus, and a few others, to be compatible with XP.
If you have this problem and want to solve it go to
www.artec.com.tw and download new drivers for your sacnner. Extract the files and then alter the properties of the setup executable. Right click on the setup.exe, select properties and then the compatibility tag. Choose windows 2000 as the target to be compatible with. After you do this you can run setup. If you have already installed drivers, remove them before you install them. Do this through control panel, add/remove hardware.
