I have had the predecessors of this scanner for over 12 years now and now the LiDE400. First Windowns XP, then Win7 Pro and now Win10 Pro. With both Win7 and Win10, the installation (from CD) did not work straight away. The CD gets the latest driver from the net anyway. Unfortunately, add-ons are also installed that only use Canon (see Window Settings / Apps: "Canon Inkjet/Printer/Fax Extended Survey Program"). In the end, I always managed and am now happy again about this excellent scanner for single scans.

It is important to uninstall all 3 Canon Apps in Windows Setup after each failed installation attempt and - very important! - now restart the computer. Without a restart before the next attempt it will not work.

The 4800 dpi is probably more of a publicity stunt. It is the native resolution, but you can only choose a resolution of up to 600 dpi (with Scan-Gear up to 1200 dpi). But don't worry, with the Scan-Gear you can also type in a higher resolution in the selection box, e.g. 4800 dpi or even 19200 dpi (interpolated resolution). But what is the point of this high resolution is another question.

Just try it, it's not a big investment. And if it works, you will enjoy it.
