Hi John,
Manufacturers of different devices, release drivers for both 32-bit and 64-bit operating systems separately. The drivers for 32-bit operating systems cannot be installed on a 64-bit operating system.
I suggest you to go to the scanner manufacturer’s website and download the drivers for 64-bit operating system.
If there aren’t any drivers available for Windows 7, then I suggest you to download the ones for Windows XP or others and install them in compatibility mode for Windows 7. Please refer to this link:

Please get back to us with the status of the issue.
