OK, I've worked it out. What used to be Intel Control Center must have been renamed to Intel Rapid Storage Technology due to naming confusion. I have a rebuild under way. Problem solved.
It would be nice to know how to change this interface from Norwegian to English, though. I must have posted a problem when I was in Norway a couple of years ago.
I'm not sure why you're seeing Norwegian, but I remember someone else who had that happen. I sent him a message to ask what he did to fix it. I'll let you know what I find out.
