I have a day off today to play with Halion. 
But that manual is 550+ pages so it is going to take some time to byte trough all of it.
As far as functionality matters: Yes, the entire peace of software is working in Win 7 it seems at first sight . The only thing i encountered, which is not something essential, is that UAC in Win 7 with restricted (guest) accounts seems to have trouble to recognize the new Halion 6 content. Software is fine, but still to premature to define it as an issue. I will check it further today.
kind regards,
R.
