I have an Avision FB1200 scanner and want to install it on windows 8 but I can't. I installed its driver which was on its CD but nothing happened. Then I tried repairing it through the same install file but there was an error message about the file "C:\windows\scanner\avsetup.dll". When I plug in the scanner to the USB port, there is balloon at the bottom right saying "USB device not recognised". What should I do?
Thanks
