I currently have an iMac in the office and a Macbook Pro for when I'm out on the road. Both have CC on them. I'd like to get another machine for the office. I have a standard subscription for all of the apps which allows me to have two active CC systems operating at the same time. Is it possible to have CC put into my third machine so I can use either both of the office machines at once or the laptop and an office machine working together? So at any one time, only two of the three installs are active? Or if I want to have a third install available to me, I have to upgrade my sub? Thanks.
