This may be hopeless, but I have an ancient Canon flatbed scanner Model CanoScan FB 620U. Does anyone know where I might find a Win 7 driver for this old beast?
I checked the website - CanoScan FB 620U
There is only XP drivers available for this device
If you have an older application for Windows XP or Vista (or even 95/98!) that no longer runs in Windows 7, you may be able to get it working properly by running the program in compatibility mode.
