Solution 1Recommended

Reset Acrobat Preference Files

Clearing out corrupted preference files often resolves startup failures and allows Acrobat to regenerate fresh default settings.

Over time, Acrobat preference files can become damaged, causing the software to crash upon opening. Resetting them forces the program to create clean configuration files.

1
Close Background Processes

Ensure Adobe Acrobat X Pro is completely closed and no related processes are running in the background.

2
Locate Preferences Folder

Navigate to the Acrobat preferences folder on your system. On Windows, press Win + R, type '%APPDATA%\Adobe\Acrobat', and press Enter.

3
Backup and Remove

Find the '10.0' folder (which corresponds to Acrobat X) and move it to your desktop to create a backup, effectively resetting the preferences.

4
Restart and Test

Restart your computer and launch Acrobat X Pro to verify if the startup issue is resolved.

Mac OS Instructions: If you are on a Mac, you can find the preference files by navigating to User/Library/Preferences and moving the 'com.adobe.Acrobat.Pro.plist' file to the desktop.

Frequently Asked Questions

Why does Adobe Acrobat X Pro close immediately after opening?

This typically occurs due to corrupted preference files, conflicting background applications, or compatibility issues with newer operating systems since Acrobat X is an older product from the CS6 era.

Will I lose my PDF files if I repair the Acrobat installation?

No, repairing the Acrobat installation only replaces or fixes the application's core system files. Your personal PDF documents and customized data will remain completely safe on your local drive.

Is Adobe Acrobat X Pro still supported on Windows 10 or 11?

Adobe officially ended support for Acrobat X in 2015. While it may still run on newer operating systems like Windows 10 or 11 using Compatibility Mode, it does not receive updates, which can lead to stability and launch issues.
