I am running vista 64 ultimate. I also decided to run SH3 (US download edition) ..................
read forum rules............ My copy is completely legit, I assure you.
This works great and it is easy, easy.
I installed SH3, updated to 1.4b,.................... Running as admin, XP2 compatibility mode.
This seems like the only option for vista 64 users, as Ubi has thus far turned a deaf ear to our plight.
