IE seems to be blocked by Emet 5.2, but Emet gives no errors onscreen nor in event-viewer. Removing IE from Emet solves the problem for now. Anyone else
it looks like unchecking EAF for IE in apps panel i Emet 5.2 makes the problem of IE not starting go away.
Problem solved for me at least.
Did this solve your problem?
Sorry this didn't help.
