    When you launch an Adobe app, you get an error stating that sign-in failed, limit has been reached, or the maximum number of activations has been exceeded.

    Activation Limit Reached

    These errors occur if you try to use the app on more than two computers. An Adobe Creative Cloud membership lets you use your apps on two computers. To use your apps on a third computer, sign out of the app on one of the first two computers. Signing out deactivates all installed Creative Cloud apps and services associated with your Adobe ID on that computer.

    To resolve the error and continue using the app on the current computer, try the following steps.

    Option 1

    This option deactivates the other computers on which the app has been activated from the current computer. You can use this option remotely, without necessarily having access to the other computers.

    1. Connect to the Internet.

    2. Choose Sign me out of other computers so I can sign in here.

    3. Click Continue.

    4. Enter your Adobe ID and password, if prompted.

    Option 2

    In this option, you need to sign out manually from another computer on which the app is installed using the same Adobe ID.

    1. Launch the app on the other computer on which you installed it, and choose Help > Sign Out.

      For detailed instructions, see Sign in and sign out to activate Creative Cloud apps.

    2. On the current computer, choose I signed out of one computer so I can sign in here.

    3. Click Continue.

    Option 3

    You can also deactivate from your account page on adobe.com.

    1. Access your Adobe ID account online, and sign in with your Adobe ID and password.

      Tip:

      Your Adobe ID is the email address you used when you first purchased an Adobe membership, application, or service.

    2. In the Plans & Products section, click Manage plan.

      Manage plan
    3. Under Activated devices, click the x next to the device you want to deactivate.

      Click next to the device you want to deactivate
    4. Click Deactivate.

      Click Deactivate

      To activate a device again, simply launch an Adobe application from that computer. You should be prompted to sign in. If not, choose Help > Sign In.

      Note:

      Remember, you can only have two devices activated at any time. Make sure that you have only signed in to your Adobe apps on one other device before signing in on (activating) a second device.


    Uninstalling the app from a computer does not deactivate its license. To deactivate the app, follow the steps in Option 1.


    If you don't have access to the other computer on which you installed the app, follow the steps in Option 1 to deactivate the app on that computer.


    Did you upgrade your computer's hardware, replace a hard drive, upgrade your operating system, or format your computer before deactivating your software? Follow the steps in Option 1 to deactivate the computer.


    Perpetual license users

    When you launch an Adobe app, you get an error stating that sign-in failed, there is an activation limit, or the maximum number of activations has been exceeded.

    Sign in failed

    These errors occur if you try to use the app on too many computers. To resolve the error, try the solutions below.


    Acrobat DC

    You can use your Acrobat Pro DC or Acrobat Standard DC subscription on two computers. To use Acrobat on a third computer, simply sign out of Acrobat on one of the first two computers.

    For detailed instructions, see Activate and deactivate products.

    Creative Suite 6 and earlier

    A single license for Adobe CS6 and earlier applications lets you install an app on two computers. However, you can use the application on only one computer at a time.

    To install the application on a third computer, deactivate the application on the computer on which you no longer want to use the software. Then, activate it on the new computer.


    Uninstalling the app from a computer does not deactivate its license. To deactivate the app, reinstall the app, and then do one of the following:

    Acrobat Pro DC or Acrobat Standard DC

    1. Connect to the Internet.

    2. Reinstall the app, sign in when prompted, and enter the serial number.

    3. Launch the app, and then choose Help > Sign Out.

    CS6, CS5, CS4, Acrobat XI, Acrobat X, or Acrobat 9

    1. Connect to the Internet.

    2. In the app, choose Help > Deactivate.

      Choose Deactivate

    CS3, Acrobat 8, or earlier products

    1. Connect to the Internet.

    2. Choose Help > Deactivate or Help > Transfer Activation.

    3. If you want to activate on another computer, select Erase My Serial Number From This Computer.

    4. When you see the Deactivation Successful message, click Exit.
