- Scenario
- Managing software licenses to ensure compliance when installing Acrobat XI Pro on multiple devices.
- Observed behavior
- Seeking clarification on the installation limit as defined by the software's End User License Agreement.
Ensure you have your Adobe ID and valid Acrobat XI Pro serial number ready, and verify which computers currently have the software activated.
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.
Log in to your Adobe account via your web browser to view which devices are currently activated using your Acrobat XI Pro license.
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.
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.

Edit PDFs Across Devices with WPS Office
If you are restricted by Adobe Acrobat's older installation limits, WPS Office offers a comprehensive built-in PDF editor. With a single WPS account, you can read, edit, annotate, and convert PDFs seamlessly across your Windows, Mac, Android, and iOS devices.
- 1. Download and install WPS Office: Visit the official WPS website, download the free version for your operating system, and follow the simple installation prompts.
- 2. Sign in to sync your account: Open WPS Office and sign in using your email or a third-party account to ensure your files and premium features sync across all your devices.
- 3. Open and edit your PDF files: Click 'Open' on the homepage to load your PDF. Navigate to the 'Edit' tab at the top to modify text, insert images, or add signatures.

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.
