Manufacturer driver may add:
Plug and Play: For the RN10D specifically, the basic functions (pointer, left/right click) are natively supported by Windows. He didn't actually need a driver for basic use.
The Oscar Editor: If he wanted to customize the buttons, he needed the specific "Oscar Mouse Editor" software, not a generic "RN10D driver."

Avoid the "Driver Updaters": Do not download .exe files from sites that look like system scanners. They are often malware vectors.
Go Official: Visit the A4Tech official site > Support > Download Center.
Check the Hardware: If your mouse is wireless, ensure the dongle isn't conflicting with USB 3.0 ports.
Locate the tiny nano USB receiver stored inside the battery compartment or taped under the mouse.
Plug this receiver into an available USB port on your computer. Ideally, use a USB 2.0 port (black plastic inside) rather than USB 3.0 (blue) to avoid rare interference.
Unplug the receiver and mouse.
Download the driver package for your OS and extract if compressed.
Run the installer as Administrator (Windows) or follow the package instructions for other OSes.
