Need a little more info.
How is the scanner connected? USB, etc.
Reboot in safe mode and see if the scanner is listed there. if it is remove it and reboot.
Make sure the scanner is attached and on when you reboot.

If your scanner is not hooked up via usb you may have to remove all twain drivers manually in the twain & or twain 32 folders within windows explorer. Also to get a clean uninstall you may have to go to regedit & go to edit then select find & type in whatever manufacturer it would be say like "ACER" & only delete what it highlights in the registry nothing more & after deleting each one hit the f3 key until it says finished searching through registry. (hope this helps)...

First remove the scanner thru device manager and then reboot. When windows restarts the device manager should start up saying it has deceted new hardware. It should also prompt you for a driver disk. If it does not then remove the device as stated before and then manually install the device. There is also a chance that the software for the scanner may setup all the necessary drivers for the scanner. Run the setup for the scanner from the software cd and see if this makes a difference. If not asa last effort check w/ the scanners website for any support info in regard to this problem.
