I tried everything, uninstalled everything with Revo Uninstaller, the registry keys, the subfolders in several places, all traces of AC but nothing helps...
Maybe this one is unfixable without update/bug fix from Asus. So did version 4.2.5 work ok? And your problem is with version 5? What was the first version of Armoury Crate that was installed on the system?
Are you getting any error messages in windows event logs for AC processes/services?
version 4 worked fine and then drama appeared without asking, version 5 tried all your workaround and more using bcu uninstaller, no way to make it work
