I found that rebooting in Safe Mode in Windows 10 solved my firmware update problems with my Strafe RGB keyboard.
I ran msconfig.exe. On the Boot tab select options to restart in safe mode with network enabled.
After restarting in safe mode, start iQue, click to update firmware. Worked this time. I ignored the error saying it couldn't start a service.
Went back to msconfig.exe, set to Normal restart on Boot tab.
After final reboot, everything workd fine.
