Hello,
Adobe has this given these hints:
http://helpx.adobe.com/creative-cloud/faq.html>>> Can I use the software I download from Creative Cloud on more than one machine? >>> Yes. Creative Cloud desktop applications can be downloaded and installed on multiple computers, regardless of operating system. However, activation is limited to two machines per individual associated with the membership. See the terms of use (General-terms) for more information. Learn how to deactivate (Activation & Deactivation Help) a Creative Cloud license on a machine.
Moreover I quoute Preran: The Adobe ID is used for the activation process. Previously you could activate only on two instances of the same OS. That restriction has been removed. Also, if you log into a third computer on which you have installed CC, you are automatically logged out of one of the previous computers where you have logged in. (
