I installed it last night. Make you sure uninstall the Beta version first if you were using it, and restart. A breeze to setup otherwise. I really like it. I think they knocked out most of the bugs in the Beta. It's great to have all your character options right there in front of you. Makes you wonder how you used to do it with those piles of books spread all over. Don't get me wrong, I still enjoy having all the books to look through and reference. But the Character Builder really is a great tool.
