If you run the exe file, you'll be fine. Just know where you installed VRC in case you need to add things in the future.
Been doing this ATC thing for awhile with only one screen. For ground tower and approach it's not too bad. It's only when you start moving out to enroute positions that you have to move around and constantly scroll. A couple words of advice, buy a mouse with a scroll wheel, they're not too expensive, probably start at 5-10$, another thing, would be using the alt+tab trick going between SOPs or cheat sheets and the scope. Finally in combination with the scroll wheel you can use the control or tab keys to scroll faster.
Cheers
