I don’t know who made these but they work, whoever you are I salute you. Since Canon are tools & wont make the drivers for the Canon LiDE 50 scanner for 64bit Windows, someone hacked them together from drivers of another (LiDE 60) Canon scanner.
Device support for this scanner is not included within Microsoft XP/Vista/Windows 7 x64 or provided as an installable driver by Canon. To resolve this lack of support please install the modified driver below.
This package is based on original Canon ScanGear driver for the LiDE 60 and includes the full ScanGear GUI TWAIN interface required to operate the scanner.
Modifications for the LiDE 50 include:
Insertion of Hardware ID
Insertion of Device ID
Replacement of LiDE 60 Colour Profile with correct LiDE 50 ICC file
Insertion of correct flatbed scan area dimensions and imaging capabilities
