A: VueScan supports some Kinghun CIS scanners, but not the high-speed CCD models. NAPS2 will see the scanner but cannot control the high-speed roller motor. You must use the OEM software.

A: During installation, look for a flag icon at the top-right of the setup screen. If you missed it, go to C:\Program Files\Kinghun\Lang and delete the zh-CN folder (backup first), forcing the software to default to en-US .

Right-click the file and select "Run as Administrator." Accept the EULA (End User License Agreement).

Remember to back up your installer immediately after download, keep your USB dongle safe, and calibrate the scanner monthly. If you continue to experience errors, Kinghun’s technical support team is known for assisting via remote desktop (TeamViewer) within 24 hours.
