A4tech Rn-10d | Driver

1. The model number is incorrect – A4tech (A4Tech) commonly uses model numbers like R8, R7, X7, OP-720, WMS-10, etc. "Rn-10d" might be a misreading or a partial code from a label on the device.
2. It's a very old or rare model – Older A4tech mice sometimes have model numbers like RN-10D, but this is not a standard listed model in their current driver database.
3. It could be a generic mouse – Many unbranded or OEM mice use A4tech chips internally but don't have dedicated drivers.

Step 3: Run the Installer as Administrator

• Right-click the .exe file → Run as administrator.
• Accept the User Account Control (UAC) prompt.

2. Do you need a Driver?

• Windows 10 / Windows 11: You do not need to download a driver. Simply plug the USB cable into the port, and Windows will automatically install the generic HID driver.
• Windows 7 / XP: You may need a driver if the mouse isn't recognized automatically.

4. Alternative: Use Windows built-in driver update

If Windows shows “Unknown device” (rare), force update the driver:

1. Open Device Manager → Mice and other pointing devices.
2. Right-click your mouse → Update driver → Search automatically for drivers.
3. Windows will install the standard HID-compliant mouse driver.
