How to Fix Logitech Gaming Software Not Opening
Source-checked · About 10 minutes
Answer
If Logitech Gaming Software starts in Task Manager but no window appears, end Logitech Gaming Software or LCore.exe and open LGS once from the Windows Start menu. If no Home screen appears, uninstall LGS from Installed apps, restart Windows, and reinstall Logitech's current package. Before reinstalling, confirm that your exact device still uses legacy LGS rather than G HUB.
Open Logitech Gaming Software once from the Start menu and wait 30 seconds. Continue here if no LGS Home screen appears, even though Windows may show LGS in the taskbar or Task Manager. If the Home screen opens and says No devices detected, use the device-detection guide instead.
Press Ctrl + Shift + Esc to open Task Manager. Under Processes or Details, select Logitech Gaming Software or LCore.exe and choose End task. Wait until it disappears, then open Logitech Gaming Software once from Start. The step worked if the LGS Home screen appears and remains responsive.

Confirm that the device still uses LGS
If LGS still has no window, find the exact device model on Logitech Support and open its Downloads page. Continue only if Logitech offers Logitech Gaming Software for it. If the model lists G HUB instead, install G HUB; reinstalling legacy LGS will not add support for a G HUB device.
Open Windows Settings > Apps > Installed apps, find Logitech Gaming Software, open its menu, and choose Uninstall. When removal finishes, restart Windows. This closes the old LCore.exe startup state before a fresh copy is installed.

Install LGS again from Logitech
Download Logitech Gaming Software from Logitech Support and run the 64-bit Windows installer. Finish the prompts and restart again if asked. Open LGS from Start before restoring any old shortcuts. The repair is successful when its Home screen opens and accepts a device selection.
Close LGS normally, wait for LCore.exe to leave Task Manager, and open it a second time from Start. Select the connected device and open one settings screen. Two normal launches and a responsive device screen confirm that the startup problem is resolved.
If it does not work
If Windows says LGS is still running during uninstall, return to Task Manager and end LCore.exe before trying Uninstall again.
Disabling Logitech Gaming Software in Task Manager's Startup apps only stops automatic launch at sign-in; it does not repair an LGS window that fails when you open it manually.
If a fresh official install creates LCore.exe but still never shows a Home screen, send Logitech Support the exact device model, Windows version, and LGS version. Do not add registry startup tasks or download a replacement LCore.exe.

This guide is for LGS producing no usable window. A visible LGS window with no hardware listed is a separate device-detection problem.
