Tricky problem with the twain driver on this system. Its looks to be all there but when you go to use any of the scanner software a twain error appears. I uninstalled the Canon N670U software then on trying to reinstall it with the CD it tells me the Twain driver needs to be installed. In device manager on WIN XP pro I tested the scanner in Imaging Devices and all was OK in there. So I used the twain driver uninstaller from Canon to remove everything. Downloaded the latest drivers for this scanner that also had the twain drivers with it. Installed these and still had the same problem when I went to install the software. Telling me to install the Twain drivers?

Isn't ScanGear CS-U supposed to function as the TWAIN driver? Also--(Note: CanoScan Toolbox v4.1.1.0X must be installed prior to installing ScanGear CS v7.0.1.0X)--from the Canon site.

This is the documentation for the N670U:

This is the driver and download page. Make sure to read the accompanying information for the downloads.

You may need to uninstall everything and start from scatch. Make sure to follow the directions about installing all the component applications that go with the scanner.
