- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Managing Adobe Acrobat installations across multiple devices and mixing subscription and perpetual licenses.
- Observed behavior
- The system shows activation-limit messages because installations exceed the allowed limit for active sessions or activated devices.
Ensure you have your Adobe ID login credentials or your perpetual license serial number ready before attempting to manage your activated devices.
Deactivate Unused Adobe Acrobat Devices
Sign out of Adobe Acrobat on old or unused computers to free up your activation limit for a new device.
Adobe Acrobat subscriptions allow installation on up to two computers, but you cannot use them simultaneously. If you reach the limit, you must deactivate an existing session to activate a new one.
Go to the Adobe account management page in your web browser and log in with your Adobe ID.
Click on 'Manage plan' under your active Acrobat subscription.
Find the 'Activated devices' section and click 'Deactivate' next to the computer you no longer use.

Frequently Asked Questions
Can I use Adobe Acrobat on two computers at the same time?
No. While an Adobe Acrobat subscription allows you to install and activate the software on up to two computers, you can only use it on one computer at a time.
What is the difference between a subscription and a perpetual license in Acrobat?
A subscription is linked to your Adobe ID and requires periodic online validation, allowing up to two device activations. A perpetual license is a one-time purchase activated via a serial number and is typically tied to a single machine.
Why am I getting an activation limit reached error?
This error occurs when you try to activate Acrobat on a third computer while already signed in on two others, or if you mix subscription and perpetual license installations improperly. You must sign out of one of the active sessions to proceed.
