Canon N67OU Problems

• Problem: “unable to select Twain source.”
• Situation: Windows XP said the scanner was fine. Neither Xnview nor the Canoscan toolbox could connect to the scanner.
• Fix: eradicate every trace of the old driver and toolbox. Reinstall same. Remove same using CD ROM's removal tool. Then install new driver and toolbox from Canon's website. I also had to make IE my default browser and change File Types so that .htm and .html were associated with IE. The Canon installation software doesn't work with Mozilla Firefox. It took about three or four hours of fussing to get one and only one NEW set of drivers installed and recognized by the system.

Well, I think that's what fixed it.
