There is no subscription that allows two users, so far as I know. One subscription can be used in two computers, yes, but only by ONE person and not at the same time; it’s like for your desktop & laptop. So so think you need three subscriptions. However you will find managing the standard retail subscriptions a nightmare, as they belong completely to the single user; the company has no right to transfer or even cancel it. You probably need to look at Team subscriptions.
