I read the above posts from users Jill and JohnQJ. So will SPSS 15.0.0 work equally well this way with 32-bit or 64-bit Win 7 Pro? Does it make a difference whether it's 32-bit or 64-bit? We're buying a new computer for a staff member but we don't want to upgrade SPSS since the 15.0.0 version still meets our needs quite fine.
