Thanks for the reply. The Twain driver was downloaded from Canon and installed. The driver is working. The Firewall was checked and it does not appear to be blocking anything associated with the scanner. I read where the latest updates are affecting some USB devices and this is plugged into a USB port. Perhaps MS willl have a fix.

Problem Description: HP Computer - Vista 64 My Canon scanner stopped working after the latest updates (10) sent out on Wednesday of this week. I called Canon support and we reinstaled the latest drivers and programs. The Canon software (Toolbox) will not operate the scanner. However, I can scan using Win Paint or the Photo Gallery since it uses the Windows driver. The Scanner software was working fine just before these latest updates. Something seems to have affected the Canon driver or software.[/size]
