You may see a digital signature error when you install Logitech Gaming Software (LGS) on

some Windows 7 computers. All recent versions of LGS require the following Microsoft

Windows security update to be installed prior to installing LGS:

 Security Update for Windows 7 Systems (KB3033929)

The security update adds support for SHA-2 driver signing and verification functionality. There

are two versions — one for Windows 7 32-bit (x86) and one for Windows 7 64-bit (x64). Make

sure you've downloaded and installed the correct version for your computer before you install

LGS.

Gaming-keyboard profile stops working in the middle of a game

When a profile stops working in the middle of a game, there are two possible causes. Either the

profile is:

1. Not associated with the correct .exe file

The profile is detected in the game launcher or menu, but stops working while playing the

game. This happens when the profile isn't associated with the correct .exe file. You can

fix this by assigning the game's .exe file to the profile and not the launcher's .exe file. See

answer 28138 for instructions.

2. Reverted to the Default Profile

Another application running on your computer may come to the foreground, causing the

active profile to revert to the Default Profile. You can fix this by locking the profile

assigned to the game. See answer 28142 for instructions.

My gaming-keyboard profile stopped working after a game update

Each profile is associated to a specific .exe file. Sometimes, when you install a game update or

expansion pack, the location of the correct.exe may change.

If you recently installed a game update and then your game profile stopped working, see

answer 28138 for help with finding the current game .exe.
