- Device & OS
- not provided
- Scenario
- Migrating Adobe Acrobat software to a new computer or reinstalling it after a system crash.
- Observed behavior
- An activation or serial number limit error occurs, preventing the software from being activated on the new device because it remains registered to the old system.
Determine whether you are using a subscription-based Adobe Acrobat account or an older perpetual-license version with a serial number, as the required deactivation methods will differ.
Deactivate from the old computer directly
Use this method if you still have access to the old computer and the Acrobat software is still installed and functioning.
The most straightforward way to free up your activation limit is to sign out or deactivate directly from the application interface on your previous device.
Launch the Adobe Acrobat application on your old computer.
Click on the 'Help' option located in the top menu bar.
Select 'Deactivate' or 'Sign Out' from the dropdown menu. Follow the on-screen prompts to complete the process. This will immediately free up the license for your new device.
Deactivate online via your Adobe Account
Use this method if your old computer is broken, formatted, or no longer accessible.
Contact Support for perpetual licenses
Use this method if you are using an older standalone version of Acrobat (like Acrobat XI or older) that does not support web-based account management.

Frequently Asked Questions
Will uninstalling Adobe Acrobat automatically deactivate my license?
No, simply uninstalling the application from your computer does not free up the activation limit. You must use the 'Sign Out' or 'Deactivate' option within the Help menu before uninstalling, or deactivate the device online.
What happens if my old computer is completely dead and won't turn on?
If you cannot access the old computer, you can log in to your Adobe account via a web browser and deactivate the device under the 'Plans' or 'Activated Devices' section. For very old software versions, you may need to contact Adobe support directly.
How many computers can I activate Adobe Acrobat on?
Typically, an Adobe Acrobat license allows you to install and activate the software on up to two computers. However, you can only actively use the software on one computer at a time.
Why is my serial number showing as invalid when I try to activate on a new PC?
This usually means the activation limit has been reached because the software is still registered to your old devices. It can also happen if you are trying to use an upgrade serial number without having a previous qualifying version installed.
