Question 1

Install fails or rolls back?

Accepted Answer

Confirm the driver matches your Windows version and x64/x86 architecture. Run the installer as administrator; if it still fails, extract the package and update the “Nuvoton CIR Transceiver” manually via Device Manager > Update driver > Browse my computer. Don’t force unsigned INF files.

Question 2

Device not detected?

Accepted Answer

Enable CIR/IR in BIOS/UEFI and check Device Manager with Show hidden devices. Rescan hardware; the transceiver may appear under Human Interface Devices or System devices. If absent, test another USB/header connection.

Question 3

Version conflicts/code 10 or 43?

Accepted Answer

Remove any older Nuvoton or Microsoft eHome IR driver, select Delete the driver software, reboot, then install the OEM-matched package. If a Windows update breaks IR, roll back the driver.
