I have never been able to get the Intel MEI driver to install from Dell's web page. The installer always encouters a "fatal" error and never completes. In device manager under system devices I see that there is a MEI entry. I'm not sure why the Dell Installer won't work. Anyways, you can download updated drivers from Intel but there are two versions...1.5 Mo and 5 Mo. Can someone please tell me how I know what version I would download? I have a Dell XPS 13 9350. Thanks.
