The driver only support for windows xp,
but the scanner still work using xp driver on windows Vista,
before installing the xp driver on windows vista, please set the driver compatibility to windows xp sp 2, then the scanner may work
1. Please delete your email address from your previous post.
2. Have you tried to connect the scanner to your computer and rebooted?
It is possible that Microsoft might have a default driver for the scanner.
After rebooting, check to see if the scanner is listed in your Device Manager.
It's worth a try.
