Find simple solutions to common activation and deactivation problems.
Activation connects an app or service to a valid user license.
For most apps, the process is straightforward and happens automatically when you sign in. However, errors can sometimes occur—for example, if you’re unable to connect to the activation server, your license isn’t active, or you’re trying to install an app on more than two computers.
Here are solutions to some common activation problems for non–Creative Cloud products.
Having activation issues with a Creative Cloud app or service? See Troubleshoot Creative Cloud activation errors.
An inaccurate computer system clock can cause activation problems. Did you reset your computer’s date and time recently? Check that your computer's system clock is set to the correct date and time.
Make sure that you are connected to the Internet before you try to activate. If you are connected and you still get connectivity errors, try the solutions in Resolve connection errors.
If you purchased a single license for Adobe software, you can install the app on two computers. However, you can use it on only one computer at any given time. To install the app on a third computer, you must deactivate the app on one of the first two computers.
Ensure that you are connected to the Internet, launch the app you want to deactivate, and
choose Help > Deactivate. For detailed instructions, see Activate and deactivate Adobe products.
If you want to run an app on multiple computers simultaneously, purchase another license from the Adobe store.
Creative Cloud, Acrobat, and subscription memberships require online activation. See Sign in to activate your Adobe apps.
For CS6, CS5.5, and CS5 products, if the computer on which your software is installed cannot connect to the Internet or to Adobe’s activation servers, you can activate your software offline. For instructions, see Offline Activation.

Deactivation is disconnecting an app or service from a valid user license. You can deactivate an app without uninstalling it from your computer, and you can reactivate it later.
Deactivation issues can sometimes occur—for example, if you can’t access the computer on which you want to deactivate an installed app.
Having deactivation issues with a Creative Cloud app or service? See Troubleshoot Creative Cloud activation errors.
Uninstalling an app from a computer does not deactivate its license. To deactivate an app, follow the steps below for your product. If you uninstalled your app from a computer you can’t access, see Have you lost access to your previous computer?
