While trying to install a acer 320u scanner to a win2000 system I ran accross a error message at the very last screen, which is after inserting the win2000 disk for the twain.dll copy. The message is "A function driver was not specified for this device instance" Everything seemed to be going well until this point but the screen that should tell me that the driver was installed correctly shows me this. Device manager shows a exclamation point next to the scanner. Any help and or further info would be great. I will provide further info if needed.
