Question details
The user needs to stop repeated "not genuine" warnings from Adobe for a legitimately purchased, older version of Acrobat when original media and serial keys are lost.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Trying to use an older, previously purchased version of Adobe Acrobat without triggering genuine software warnings.
- Observed behavior
- Adobe Genuine Software Integrity Service displays warnings indicating the software is not genuine or unauthorized, despite being purchased legitimately years ago.
Before troubleshooting, gather any surviving purchase records, company receipts, or emails from the original reseller, as support teams will require proof of purchase to verify your legacy license.
Verify Your License with Adobe Support
The most secure way to resolve genuine software warnings for older licenses is to have Adobe manually verify your purchase history and check for revoked keys.
In many cases involving software purchased more than a decade ago, the original reseller may have distributed unauthorized volume keys that were later revoked. Contacting official support can help clarify the status of your specific license.
Find any company invoices, emails, or reseller details related to the original Acrobat purchase.
Note the exact version of Adobe Acrobat installed on your computer and your current operating system version.
Reach out to Adobe Support via their official website, navigate to licensing and activation support, and provide your documentation to check if your serial key was invalidated.

Recover Lost Serial Keys from Your System
If you lost the original box and disc, you might be able to extract the product key from your system files or your online account.

Frequently Asked Questions
Why is my legitimately purchased Adobe Acrobat showing a 'not genuine' warning?
This can happen if the software is very old and no longer supported by modern operating systems, or if the original reseller from years ago was found to be unauthorized and their issued volume keys were subsequently revoked by Adobe.
Can I disable the Adobe Genuine Software Integrity Service?
While some users attempt to disable the service via Task Manager or macOS Activity Monitor, it is not recommended as the warnings will typically return upon the next system update or application launch.
Does Adobe still support Acrobat versions purchased over 10 years ago?
No. Support for older perpetual license versions (like Acrobat X or XI) has been phased out. Once a product reaches its end-of-support date, it no longer receives security updates and may experience severe compatibility issues on newer operating systems.
