Adobe Creative Cloud (CC) applications
An Adobe Creative Cloud membership lets you use your applications on two computers—for example, at home and at the office.
To use your applications on a third computer, sign out of the application on one of the first two computers. Then, youcan sign in to the application on another computer.
Creative Suite (CS) 6 and earlier Adobe applications
A single license for Adobe CS6 and earlier applications lets you install the application on two computers. However, you can use the application on only one computer at a time.
To install the application on a third computer, deactivate the application on the computer on which you no longer want to use the software. Then, activate on the new computer.
