i got my Artec e+Pro usb scanner to work under vista.
1) download the xp version driver of the above scanner onto the desktop.
2) right click the exe icon.
select compatibility as xp service pack 2
RUN as administrator
allow this program to run even though it has not been aproved by microsoft.
3) go to c:/windows/twain_32/ePlusPro/Scan32.exe
right click SCAN32.exe
select compatibility as XP service pack 2
RUN as administrator.
i actually created a shortcut to the desktop of scan32.exe.
Now everytime i click on this..........my artec e+pro scanner work absolutely fine.
