Fix Acrobat Pro DC License Reported as Invalid on Second Mac
Question details
The user needs to successfully activate their Acrobat Pro DC license on a second Mac without it triggering an invalid or deactivated error.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- Mac
- Scenario
- Activating a previously purchased Acrobat Pro DC license on a second permitted device.
- Observed behavior
- The software works normally on the first Mac, but is reported as deactivated or illegitimate when activation is attempted on the second Mac.
Ensure you have the exact Adobe ID credentials associated with the original purchase and verify that your license strictly permits installation on a secondary device.
Deactivate Previous Devices via Your Adobe Account
Use this method if you have reached your device activation limit or need to reset the license connection for the new Mac.
Adobe licenses typically allow installation on up to two computers, provided they are not used simultaneously. If the system detects conflicting sessions or previous hidden activations, the license may be flagged. Deactivating older devices can clear this bottleneck.
Navigate to the official Adobe website and sign in using the Adobe ID associated with your original Acrobat Pro DC purchase.
Go to the 'Plans and payment' section and select 'Activated devices' to view all computers currently tied to your license.
Locate any old or unrecognized devices, including your first Mac if you plan to transfer the license fully, and click 'Deactivate'.
Open Acrobat Pro DC on your second Mac, sign in again with your Adobe ID, and complete the activation process.
Verify Purchase Legitimacy with Adobe Support
Use this solution if deactivating other devices fails, particularly if the software was purchased from a third-party marketplace.

Frequently Asked Questions
How many computers can I install Adobe Acrobat Pro DC on?
Adobe allows you to install Acrobat Pro DC on up to two computers (e.g., a desktop and a laptop) with a single license, provided you do not use the software on both devices at the exact same time.
Why is my Adobe license suddenly showing as illegitimate?
If you purchased the software from an unauthorized third-party marketplace, it may have been a volume license or a fraudulently obtained key. Adobe periodically audits these keys and deactivates those that violate their terms of service.
How do I sign out of Adobe Acrobat on a broken or inaccessible Mac?
You do not need access to the old computer. Log into your Adobe account online via a web browser, navigate to the 'Activated devices' section under your plan details, and remotely deactivate the inaccessible Mac.
Can I use WPS Office to edit PDF files if my Adobe license fails?
Yes, WPS Office comes with a powerful built-in PDF editor that allows you to view, annotate, convert, and edit PDF documents without needing an active Adobe Acrobat subscription.
