How to Fix Acrobat XI Pro Requiring Qualifying Serial Number on Mac
Question details
The user is unable to complete the installation of Acrobat XI Pro on a new Mac because the installer requests a qualifying full-version serial number.
- Product
- Adobe Acrobat XI Pro
- Device & OS
- Mac (MacBook Pro, Mac Mini)
- Scenario
- Transferring an existing Acrobat XI Pro upgrade installation to a new Mac device.
- Observed behavior
- The installer accepts the upgrade serial number but pauses the installation, asking for the serial number of a previously purchased full version to verify upgrade eligibility.
Ensure you have your Adobe account login credentials handy, as you will need them to access your previously registered product serial numbers.
Provide the Original Full-Version Serial Number
Since you are installing an upgrade version of Acrobat XI Pro, you must provide the serial number of the older, full version (e.g., Acrobat X) to prove upgrade eligibility.
Upgrade licenses are sold at a discount because they require you to already own a previous full version of the software. When transferring this software to a new computer, the installer needs both the new upgrade key and the old original key to complete the setup.
Go to the official Adobe website and sign in using the Adobe ID associated with your software purchases.
Navigate to the 'Plans and Products' or 'Registered Products' section to view a list of all your purchased software and their respective serial numbers.
Look for the older, full version of Acrobat (such as Acrobat 9 or Acrobat X) that you owned before purchasing the Acrobat XI Pro upgrade, and copy its serial number.
Return to the Acrobat XI Pro installer on your Mac Mini. Enter your Acrobat XI Pro upgrade serial number first, and when prompted for the qualifying product, select your older version from the drop-down menu and paste the older serial number.

Frequently Asked Questions
Why does Acrobat XI Pro ask for two different serial numbers?
If you purchased an 'Upgrade' edition of Acrobat XI Pro, the installer requires the new upgrade serial number as well as the serial number from your previously purchased qualifying product (like Acrobat X) to verify that you were eligible for the discounted upgrade pricing.
How can I retrieve my lost Adobe serial number?
You can typically find your registered serial numbers by logging into your Adobe account online and navigating to the 'Registered Products' section. Alternatively, check your email archives for original digital receipts or the back of your physical installation disc case.
Do I need to deactivate Acrobat on my old MacBook Pro before transferring it?
Yes, it is highly recommended to open Acrobat on your old Mac, go to the Help menu, and select 'Deactivate' or 'Sign Out' before uninstalling. This process frees up your activation seat, preventing activation limit errors on your new Mac Mini.
