I had to install it
I had to install it 3 separate times, was saying an error when opening up. Glitchy / I really hate the need to log into steam to play. Or at least, I cannot seem to get it to work without the steam intrusive operation opening and running. I had the old g5 and G6 w/ disk- but better experience operating in the computer. No very happy with the performance of this operating process. AND I have two laptops / two houses. Do not know now if I will be able to utilize this system when at the weekend house.
