So no problem I've hardly imagined: plug it to USB Windows 7. When connected to the Internet to get the latest Win7 drivers outdated automatically from the network and installs it. Only 7 MB download. After the scanner is under all the applications that can deal with scanner (graphic programs, Office, etc.) available. The included Canon CD can thus remain in the envelope - and the installation of more than 100 MB "great" Canon programs remains a fortunately spared. The scans are properly. Class!
