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.

Note:

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. Or, contact us for help. Have your serial number or Adobe ID ready.

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.

If you cannot access the previous computer on which you installed the app—whether it was stolen, was lost, crashed, or locked—you need to contact us by chat or phone. To ensure a quick resolution, be sure to have any purchase-related information ready.

Creative Cloud, Acrobat DC, 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.

Here are some common activation error codes and their solutions.

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.

Here are solutions to some common deactivation problems.

Note:

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?

Make sure you’re connected to the Internet. Reinstall Acrobat Pro DC or Acrobat Standard DC on the same computer on which it was originally installed.

Our aging activation servers for earlier versions of Acrobat and Creative Suite (CS) applications had to be retired. Without the activation servers, these applications display an activation or connection error when trying to verify a license. To install a version that doesn't require activation, see either Error: 'Activation Server Unavailable' | CS2, Acrobat 7, Audition 3 or Activation or connection error | CS3, Acrobat 8.

Affected applications include: Creative Suite 2 and 3 applications, Acrobat 7 and 8 (Standard and Professional), and Acrobat 3D Version 8.

For more details, see Activate and deactivate products.

If you cannot access the previous computer on which you installed the app—whether it was stolen, was lost, crashed, or locked—you need to contact Adobe to deactivate the app.

If you upgraded your computer’s hardware, replaced a hard drive, upgraded your operating system, or reformatted your computer before deactivating your software, you may have disrupted the activation connection.

Contact us. Have your serial number or Adobe ID ready.

If the software you’re trying to deactivate is part of a suite, deactivate another app in the suite. Launch any app in the suite, and then choose Help > Deactivate.

If your company purchased the product under a volume licensing agreement, the deactivate option isn’t available. Contact your volume licensing administrator for help.

Why do I need to activate or deactivate my apps?

Activation validates your software license by contacting Adobe servers periodically. The frequency depends on the app and your plan.

Deactivation disconnects your app from your computer. You can then activate the apps on another computer or later reactivate them on the same computer.

Make sure your computer is connected to the Internet.

If prompted, sign in. Your app is now activated. Otherwise, choose one of the following options from the Help menu depending on your app:

If you see Sign Out in the menu option, it means you are already signed in.

Make sure your computer is connected to the Internet.

Open the app that you want to deactivate, and sign in if prompted.

Choose one of the following options from the Help menu depending on your app:

If you select Help > Deactivate choose one of the following options (when prompted):

Deactivate or Suspend Activation: Temporarily deactivates the app, but retains licensing information on your computer.

Deactivate permanently: Removes the licensing information from your computer and requires you enter a serial number to activate again.

If you still have issues in activating or deactivating your apps, see one of the following:

If you bought a new computer and want to transfer your apps to it, simply deactivate your apps from the old computer so that you can use them on the new computer.

Uninstalled or deleted your app?

Uninstalling or deleting the app from the old computer or formatting the computer does not deactivate the app.

Old computer no longer available?

If the computer on which you installed the product is no longer available (for example you have lost the computer or formatted the hard drive or the hard drive has crashed), you can deactivate your apps from the account management page. Then install the apps on the new computer and follow the onscreen instructions.

If you have more than one Adobe ID, check that you are logged into your account with the correct ID. If you are not logged in with the correct ID, sign out and then sign in to the Creative Cloud desktop app. For more details, see Stop Creative Cloud from showing trial mode after purchase.

Uninstalling an app from a computer does not deactivate its license. You may still install the app on the new computer. When prompted to sign in, follow the onscreen instructions to deactivate the app on the old computer.

Still facing problems? See Activation and deactivation troubleshooting.

Activation stores information about your license in encoded form on the system hard drive of your computer at the following locations:

The following types of information may be sent to Adobe during activation:

• Unique IDs (generated by Adobe) specific to your machine and to the license you have purchased for the software. These IDs cannot be used to locate your machine or identify you personally.
• Your Adobe ID, if you have logged in to Adobe as part of the installation, update, or use of the Adobe software. The Adobe ID personally identifies you, and links to all information that you have provided to Adobe while creating or using your Adobe account. If you or your company uses an administrator or other authorized party for the foregoing, Adobe may also receive the Adobe ID of that party.

• Operating system type and version
• Locale (language dialect and writing system) in use
• Local machine time (including time zone)
