Unfortunately, there is no driver for SHARP AR-5316E. I have checked the official website of the manufacturer's, but nothing could be found for this device. The Microsoft Compatibility program also lists the program as being incompatible with Windows 8. You will have to install another version of Windows to have the device working.
