Activation connects an app to a valid user license. You need to activate your apps in order to use them after purchasing a plan.
Do one of the following:
- If asked to sign in: Enter your Adobe ID (usually your email), and click Sign in.
- If not asked to sign in: Choose Help > Sign In, then click Sign in now. Enter your Adobe ID (usually your email) and password, then click Sign in. (If the Help menu displays Sign Out (your Adobe ID), you are already signed in.)
Once you are signed in, your Creative Cloud license and all installed apps and services are activated automatically.
If you're already signed in on other devices, app versions Creative Cloud 2019 prompt you sign out. See, Device activation limit | Creative Cloud 2019.
Deactivation disconnects your apps on a specific computer from your user license. Deactivating allows you to install and run apps on a new computer. (A single license for Adobe software lets you install an application on two computers. See On how many computers can I install my apps?)
If the Creative Cloud desktop app doesn't restart, launch it manually:
Windows Choose Start > Programs > Adobe Creative Cloud
Mac OS Choose Go > Applications > Adobe Creative Cloud > Adobe Creative Cloud
