Depends. As long as you are the only user you can. But if several people are using the computer (like a studio computer) you can't install using the same license on another machine.
Our full EULA has this to say on the matter:
You may EITHER install and use copies of the SOFTWARE PRODUCTS on any number of computers provided that the Software may never be shared or used at the same time on different computers, OR install and use copies of the SOFTWARE PRODUCTS on one single computer provided that all users are physically present at the computer.
