Hi amritpaulsingh,
Your scanner is supported up to Windows Vista (32-bit only).
You can try using the latest driver and software from our website in Windows compatiblity mode (redirects you to a non-Canon site), but if that does not work then you will need a scanner compatible with your version of Windows.
I would also like to offer you participation in the Canon Upgrade Program, a one-time discount on the purchase of a replacement. If you are interested, more information is available through our phone-based Canon Direct agents at 1-800-385-2155.
