If I'm running a 64-bit version of Windows, do I need 64-bit drivers for my devices?
Yes, all hardware devices need 64-bit drivers to work on a 64-bit version of Windows. Drivers designed for 32-bit versions of Windows won't work on computers running 64-bit versions of Windows.
If you are unsure whether there is a 64-bit driver available for your device, see Update a driver for hardware that isn't working properly or go to the device manufacturer's website.
