As a gamer whom have 4 Logitech Products, i have suffered alot in the past to make the LGS work ! There product quality is amazing but there software without doubt it's one of the most Shitty application i have ever dealt with.
Anyway i will write all the steps until make your LGS work based on my experience
Most Known case is due to
USB 3.0 with software services with products such as (G35, G430, G633, G930, G933)
Note: You dont need to unplug your keyboard, if have any USB ports, unplug all connected devices to not make it work as hub.
Case 1:
1) End Task all Logitech Executable any of (LCore, Services, Framework)
2) Restart Computer and try again
3) If it work, customize your profile as you want, IF NOT go to case 2
Case 2:
1) Unplug your Logitech device that have USB 3.0 (Blue USB End)
2) Start LGS
3) If it work, plug your Logitech Product and enjoy until next software update and repeat the same steps, IF NOT go to case 3
Case 3:
1) Unplug your Logitech device that have USB 3.0
2) Download Latest LGS software (http
/support.logitech.com/en_us/software/lgs)
3) Install Application and
restart Computer
4) Start LGS ! If it work, plug your Logitech Product and enjoy until next software update and repeat the same steps, IF NOT go to case 4
Case 4:
1) Unplug your Logitech device that have USB 3.0
2) Since you have download the new LGS, it could be a profile issue so do WindowsKey + R and type:
%LOCALAPPDATA%\Logitech
3) You will find folder called "
Logitech Gaming Software",
rename it to something like "
Logitech Gaming Software Old"
Note: If it give you error, then go to Task Manager and End Task all Logitech Executable any of (LCore, Services, Firmware)
4) Start LGS ! If it work, plug your Logitech Product and enjoy until next software update and repeat the same steps, IF NOT then maybe you have an error on windows level that prevent the application from starting
I got a case at my friends computer where his C++ 2012 was not installed and gave him a bit of issues so keep that in mind that you mind need to install C++ 2010/ 2012/ 2013/ 2015
