On how many computers can I install the software I download from Creative Cloud?
You can install the desktop applications available in Creative Cloud on your primary computer and one backup computer, as long as they are not running at the same time. You will have access to both the Mac OS and Windows versions, so if you have a Mac at home and a PC at work, for instance, you can install your applications on both.
