Armoury Crate, Aura, you name it. I have near given up. And yes, it's all about the registry. It seems to me you have to use third party software to remove everything, and then start again. And maybe that will work, maybe it won't.
Who can be bothered any more? In a day or two, or week or two, and it won't be working again. Apparently, there is a new version of Armoury Crate being tested. Let's hope Asus and Microsoft (which is at least in part responsible here) get it right for a change. Then again, that may take a couple years, if ever.
