For recommended installation, run SetupME.exe inside the ME_SW folder.
This automatically installs all the ME components compatible with your system.

For minimal installation, run MEISetup.exe inside the MEI-Only Installer folder.
This will only install drivers for the ME Interface. 

Files inside the WindowsDriverPackages folder allow you to install the ME components individually.
To install, right-click on the selected INF files and choose the "install" option.
