I suggest downloading the trial first and see if it works for you. I have had all kinds of issues getting it to work, other than the very first time I installed it. Every update since and the newest version have come with issues. It could be that if you NEVER apply an update of any sort after the initial installation and setup you'll be alright, as I didn't have any issues until the first PD8 update. I am running Windows 7 Enterprise and Office 2010, among other things, on a MacBook Pro with Mavericks. It's not the MacBook, it's the PD9 software. Be prepared to spend a lot of time troubleshooting.
