1. I created a Windows 8 64-bit bottle, named it ProFantasy, to install all of their software into.
2. I installed .NET 4.0, just to be safe. I'd planned on installing RealmWorks into the same bottle, but RW wouldn't work well on the Windows 8 platform.
3. Download the CC3+ installer from the ProFantasy website. Additionally, I downloaded all of the products I own, which includes City Builder, Dungeon Designer, Character Artist, Cosmographer, and Fractal Terrains.
4. Run each of the installers, input your serials and then when complete you will have access to all of the products in one bottle.
