I am trying to upgrade to a new computer from my old Vista machine. My new machine started out with Windows 8/8.1 and I have upgraded to 10. I downloaded Steam and Civ V (vanilla) onto the new machine, but when I start the game, I get no pointer from my mouse. My machine doesn't have a touch screen, so it makes gameplay almost impossible. I can get the buttons to light up by moving the mouse around so I was actually able to start a game, but it took me almost 5 minutes to instruct my settlers to found my capitol. The pointer is present everywhere else, including the rest of my games in Steam. Very frustrating, and confusing.
