If the driver is present but "corrupted," removing specific filter keys can help. Open (Registry Editor).

The you see when launching either software version.

Since Windows 10 and Windows 11, the operating system strictly blocks unsigned kernel-mode drivers from executing. Virtual emulators (like the classic MultiKey driver written by independent developers) often lack Microsoft-validated digital certificates, resulting in a blocked driver execution.

When digital signatures fail or structural conflicts occur, Windows marks the Virtual USB MultiKey device with a yellow exclamation mark and throws Code 39 ("Windows cannot load the device driver... driver may be corrupted or missing").
