Install on Up to Two Computers

According to the Acrobat End User License Agreement (EULA), you are permitted to install the software on a maximum of two computers.

Under section 2.1.3 of the Acrobat End User License Agreement, a single license allows you to install and activate Acrobat XI Pro on up to two computers (such as a primary desktop and a secondary laptop). However, you are not permitted to use the software on both computers simultaneously.

Check current activations

Log in to your Adobe account via your web browser to view which devices are currently activated using your Acrobat XI Pro license.

2
Deactivate an old device (if necessary)

If you have already reached the two-computer limit, open Acrobat on one of the older computers, click 'Help' in the top menu bar, and select 'Deactivate' or 'Sign Out' to free up an activation slot.

3
Install on the new computer

Download the Acrobat XI Pro installer on your new computer, run the setup wizard, and enter your serial number when prompted to complete the installation and activation.

Frequently Asked Questions

Can I use Acrobat XI Pro on both computers at the exact same time?

No. While the End User License Agreement allows you to install Acrobat XI Pro on two computers, it strictly prohibits using the software concurrently on both devices.

What happens if my computer crashes and I cannot deactivate my Acrobat license?

If you are unable to access the program to deactivate it manually (e.g., due to a hard drive failure), you will need to contact Adobe Customer Care directly so they can manually reset your activation count.

Is Adobe Acrobat XI Pro still safe to use?

Because Adobe ended technical support and security updates for Acrobat XI Pro in October 2017, it is vulnerable to security risks. It is recommended to use an actively updated PDF application instead.
