Hi I recently had a similar issue - after a system restart (unlrelated to logitech peripherala) LGS wouldn't open - No matter what I tried - uninstalled and re-installed various versions of LGS and still it wouldn't open - lcore.exe was never in processes list etc.
UNTIL, I tried version 8.53.154, during the installation it asked me to disconnect my G930 head phones, once that install had finished I kept my g930 headphones unplugged and installed version 8.81.15 and VOILA - it installed and is now open, plugged in the g930 and they were detected and LGS is still working.

All other versions except 8.53.154 never prompt to disconnnect any peripherals, I would try unplug any you have except maybe mouse as you need this to carry out install or keyboard etc.

I have been working at this issue for hours trying every possible solution mentioned on the Internet. Nothing seems to be working. I have a g910 a g502 and a g930. The Logitech gaming software was working just fine until tonight. I did install a new graphics card 970 ftw and updated the drivers. I believe that triggered the issue originally. But now no matter what I do of what version of the Logitech gaming software I install it simply will not open. I have tried uninstalling the nvidia drivers, installing countless versions of C++ and there is nothing. Lcore will not launch at all.

Machine specs are
Mobo: MSI z170 titanium edition
Processor: Intel i7 6700K

RAM: 16gb Gskill rip jaws DDR4 2400

Card: 970 FTW EVGA

WINDOWS 10 Home

Do you have other Logitech hardware?

I'm using win 10 x64 and the x64 version of LGS. I have a G600 mouse (the reason i suffer this software) and a G930 headset. On restart my LGS will not load, just the lcore.exe, but the software does not load. I found if unplug the G930's usb dongle and re-launch the software it loads fine, but with the headset plugged in it refuses to.

Im using windows 8 x64 with the x64 version 8.5.8 (Older version) of LGS
I tried all other solutions I could find on the internet, but the only way i got it working is using the 8.5.8 version of LGS software.
Only downside to that is now i cannot use the arx docking station app since that requires 8.7.0.
Im using the 930 headset, logitech G910 Keyboard, and the G500 Mouse.

This worked for me, thank you for taking the time to let us all know, GOOD ON YOU!

I'm having this exact problem after updating today, but your fix didn't work for me. It's rather frustrating.
