- Product
- Adobe Acrobat / Reader
- Device & OS
- not provided
- Scenario

Ensure your internet connection is stable and save any pending work in your current PDF documents before initiating a software update.
Update Acrobat or Reader to the Latest Patched Version
Applying the official software patch is the primary and recommended method to resolve the URL-handling and security compatibility bugs.
A 2019 update introduced changes to security protocols that inadvertently broke XDP link routing. Adobe released a specific patch (19.010.20069) to restore this functionality.
Launch your Adobe Acrobat or Adobe Reader application on your computer.
Click on the 'Help' menu in the top navigation bar and select 'Check for Updates'.
Follow the on-screen prompts to download and install the latest available version, ensuring it is at least release 19.010.20069.
Once the installation is complete, restart the application and click the XDP link again to verify the form loads correctly.
Verify Server Response and Browser Integration
If updating does not completely resolve the issue, verify that your server is responsive and your browser's PDF handler settings aren't overriding Acrobat.

Frequently Asked Questions
What is an XDP file and how is it used?
An XDP (XML Data Package) file is an XML-based format created by Adobe that packages PDF form data, including XFA (XML Forms Architecture) information, to efficiently transfer form layouts and data.
Why did my XDP links open in a browser instead of Acrobat?
A specific 2019 update to Acrobat and Reader introduced URL-handling and security changes that inadvertently conflicted with how HTTP links in XDP files are processed, routing them to the default browser instead of the application.
Should I disable Enhanced Security in Acrobat to fix this bug?
No. Disabling security features like Protected View or Enhanced Security exposes your system to vulnerabilities and is not a recommended workaround. Applying the official update patch is the safest fix.
Will updating my software restore the auto-population of XFA data?
Yes, installing patch 19.010.20069 or a newer version explicitly addresses this bug, allowing Acrobat to correctly load the referenced PDF and populate its associated XFA form data.
