I have noticed that some people are having quite a bit of trouble installing this on the 64bit side, even though there are already threads telling them how. I have tried it on windows 7 home premium 64 bit, as well as windows 7 ultimate 64 bit. I am in no way responsible for any damages caused to you, or your car, or your bmw scanner for any of this.
Edit: Oh yeah, in case you're all wondering.
