I ran into a problem with the original TwainDemo on Windows 10 Pro 64bit. If I compile for Windows 32 everything is fine and the devices are all shown in the combobox. If I complie for Windows 64 no device is shown.
Am I doing something wrong? Is it not implemented?

Thanks to both of you for your infos! I wasn't aware of that. So I have to switch to WIA for scanning in a 64bit application since I didn't even find information about 64bit drivers. Drivers for Windows 10 64bit are apparently not sufficient.
