Creative Cloud trials are "try and buy", allowing you to evaluate individual products or editions and then convert the installed trial to a full version. You can convert from a trial to a full version at any time by signing up for a subscription. If you purchase a subscription, make sure that you are online and have logged in with an Adobe ID to start using your full version.
