how do I install creative cloud on multiple computers using the same license?

Installing on multiple computers can be done independent of the subscription.  You only need the lic3ense when it comes to activating, of which you can have two activated installations (signed in).  Just install the desktop application and use it to install the apps, then sign in to activate.
