How to Fix Adobe Acrobat Not Starting on Windows 10
Question details
The user is experiencing an issue where Adobe Acrobat fails to launch on Windows 10 version 1809 despite working normally in the past.

- Product
- Adobe Acrobat
- Device & OS
- Windows 10 (Version 1809)
- Scenario
- Attempting to launch Adobe Acrobat to view or edit PDF files on a Windows desktop environment.
- Observed behavior
- The application fails to start, hangs, or crashes immediately upon launch without opening the requested PDF files.
Ensure that your Windows 10 operating system is fully up to date and close any background Adobe processes using the Task Manager before attempting these fixes.
Reset Adobe Acrobat Preferences
Corrupted preference files are a common cause of application startup failures. Resetting them forces Acrobat to generate fresh, error-free configurations upon its next launch.
When Acrobat crashes unexpectedly or updates improperly, its preference files can become corrupted. Deleting or moving these files is a safe first step, as the application will automatically rebuild them.
Press the Windows Key + R to open the Run dialog. Type '%appdata%' and press Enter to open the Roaming folder within AppData.
Navigate to the 'Adobe' folder, then open the 'Acrobat' folder. You will see a folder named with your specific version number (e.g., DC or 2017).
Move the 'Preferences' folder to your desktop as a backup, or rename it to 'Preferences_old'.
Double-click the Adobe Acrobat shortcut to launch the application. A new preferences folder will be created automatically.

Perform a Clean Reinstallation of Acrobat
If resetting preferences does not work, a corrupted or missing application file might be the culprit. Reinstalling the software ensures all core files are intact and properly registered in Windows.
Open, Edit, and Manage PDFs Easily with WPS Office
If Adobe Acrobat continues to fail on your Windows 10 system, you can use WPS Office as a fast, reliable alternative to instantly view, edit, and convert your PDF files without any startup issues.
- 1. Download the software: Download and install WPS Office for free on your Windows 10 PC.
- 2. Launch the PDF tool: Open the WPS Office dashboard and click on the 'PDF Edit' module from the main interface.
- 3. Open your document: Click 'Open', select your target PDF file, and immediately begin viewing, editing, or annotating your document.

Frequently Asked Questions
Why does Adobe Acrobat suddenly stop working on Windows 10?
Acrobat can stop working due to corrupted preference files, conflicting background processes, incomplete Windows 10 updates (like version 1809 compatibility bugs), or missing core application files.
Will resetting Acrobat preferences delete my PDF files?
No, resetting the preferences folder only reverts the application's interface and behavior settings to their default state. Your saved PDF documents and data remain completely unaffected.
What should I do if Acrobat still won't open after a clean reinstall?
If reinstalling does not resolve the startup issue, try running the application as an Administrator, checking for conflicting third-party antivirus software, or utilizing a reliable alternative like WPS Office to access your PDFs immediately.
