Digital signature error when Logitech Gaming Software is

installed on Windows 7 computers

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.
