I've tried to install this on 3 different PC's with no luck. I even tried it on a Mac using Parallels. Each time I try, the CD spins up, spins down, spins up, etc. etc. This happened on Windows 7, Vista and XP. Either I have a dodgy disc or it is seriously flawed.
After a month of trying I finally gave up and stopped trying.
Looking at other reviews, it seems it either works brilliantly, or like mine, refuses to load.
Now learning Japanese via Rosetta Stone which just works well.
