How to Fix Aruba PEC PDF Attachments Not Opening in Adobe Reader

Product: Adobe Reader / Aruba PEC
Device & OS: not provided
Scenario: Attempting to open and view a certified email (PEC) PDF attachment on a mobile device.
Observed behavior: When selecting Adobe Reader to open the PDF, the application exits unexpectedly and loops the user back to the app selection screen.

Before you start

Ensure that the Aruba PEC app is updated to its latest version, and try downloading the attachment locally to your device before opening it to rule out temporary download glitches.

Solution 1Recommended

Use an Alternative PDF Viewer App

Since a recent update caused Adobe Reader to crash, using a different PDF application is the fastest and most reliable way to access your Aruba PEC attachments.

Software updates can occasionally introduce bugs that break compatibility between specific applications. Until the developer patches the crash, switching to a different PDF reader will allow you to bypass the error and access your important documents immediately.

Install a new PDF reader

Download and install an alternative PDF reader, such as WPS Office, from your device's respective app store.

Open the Aruba PEC message

Navigate to the Aruba PEC app and open the email containing the affected PDF attachment.

Trigger the app selection menu

Tap on the PDF attachment. If it doesn't automatically ask for an app, tap the 'Share' or 'Open With' icon.

Select the new viewer

Choose your newly installed PDF viewer (e.g., WPS Office) from the list instead of Adobe Reader to successfully open the file.

Set as Default: You can select 'Always' when choosing the new PDF viewer so you don't have to repeat this process for future attachments.

Solution 2

Contact Adobe Support for a Patch

Report the crash to the app developers so they can investigate the conflict and issue a bug fix in a future update.

Frequently Asked Questions

Why is my PDF app crashing when I open a PEC attachment?

This issue is typically caused by a bug introduced in a recent update to the PDF reader app. The update may have broken how the app handles file data handed over by the Aruba PEC application.

Are my PDF files corrupted if they return to the app selection screen?

Not necessarily. If the application exits immediately and loops back to the selection screen, it is usually a software crash or compatibility issue rather than a corrupted PDF file.

How do I change my default PDF app on my mobile device?

On Android, go to Settings > Apps > Default apps (or Manage Apps), locate your current PDF reader, and clear its default settings. The next time you open a PDF, you will be prompted to choose a new app. On iOS, you can use the Share sheet to select a different application and manage your viewing preferences.
