Question about Canon CanoScan D646U Flatbed Scanner
Whenever I am trying to install the Software CD (supplied with my Canon Flat Scanner D646U ex), it gives the massage : TWAIN Driver is not istalled which is needed for scanning pictures. All the other components of the software are being installed by means of the Installation CD. Please solve the problem.

Using the Windows XP driver MAY work. However, the D646Uex is not officially supported in Windows Vista. There is apparently some functionality limitations that prevent it from being officially compatible.

Dear Sami Kotaich,
unfortunately your Cannon has not released drivers for vista for this product.
I can give you one suggestion; connect your scanner with vista PC and atleast let it try to install necessary USB drivers. once it has been done you will see message your hardware installed or there was a problem installing drivers for your hardware and it may not work properly.
now leave scanner connected and go in start menu- programs- accessories- paint
once you are in paint click on File Menu then From Scanners or Cameras. if it does recognize and you get scan wizard then you will be able to use your scanner on vista. but if it doesn't recognize then I am sorry you might need to get more authentic recommendation from Cannon support.
let me know does it work or not? or if any more questions, please do not hesitate to contact me.
