Seriously Fun Mac and Windows Software

Windows v5.5    2 Sep 19


WoW G910


When I open the app the main windows says “Unable to start the Logitech LED driver. Please ensure LGS is running.” I’m sure LGS is running.


Several users have reported seeing this message. For almost all of them, reinstalling LGS and rebooting the computer fixed the problem. 

LGS for Windows is available in both 32-bit and 64-bit versions. If you reinstall LGS and it still doesn’t work, try installing the other bit version. There’s no problem running 32-bit LGS in 64-bit Windows.
