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 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.

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?
Choose your Product
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.
Acrobat DC subscription (purchased via Creative Cloud or Document Cloud)
Do any one of the following:
Acrobat DC (perpetual license)
Launch the app and sign in when prompted. Then choose Help > Sign Out [Your Adobe ID].
Make sure you’re connected to the Internet. Reinstall your app on the same computer on which it was originally installed. In the app, choose Help > Deactivate.
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.
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.
