How to Fix PDFs That Automatically Close After Opening in Acrobat
Question details
Users experience an issue where PDF files, especially digitally signed documents from services like DocuSign, automatically close or crash a few seconds after being opened.

- Product
- Adobe Acrobat
- Device & OS
- Windows, macOS
- Scenario
- Opening and viewing a digitally signed PDF document in a desktop application.
- Observed behavior
- The PDF file opens successfully but unexpectedly closes or crashes on its own within a few seconds.
Ensure your computer's operating system is fully up to date and that you have administrative privileges to modify security settings or create test user profiles if needed.
Update the PDF Reader and Open the File Locally
Outdated software versions or issues with shared network drives are the most common causes for PDFs closing unexpectedly.
Running the latest version of your PDF software ensures that known bugs related to signature verification and background processes are patched. Additionally, network latency can sometimes interrupt the file loading process.
Open Acrobat, navigate to 'Help' on the top menu bar, and click 'About Acrobat' to check your current version. Then click 'Help' > 'Check for Updates' to install any available patches.
If the PDF is stored on a shared network drive or cloud folder, copy the file and paste it directly onto your computer's local Desktop.
Open the locally saved PDF document to see if the issue of it closing automatically persists.

Temporarily Disable Protected Mode (Windows)
Strict application security settings can sometimes conflict with digitally signed documents, causing them to force-close.
Test with a New User Profile
A corrupted operating system user profile can cause applications to crash when verifying document signatures or loading preferences.
Use WPS Office to Open PDFs Without Crashing
If your current PDF viewer keeps closing documents automatically, try WPS Office. It includes a highly stable, lightweight PDF reader that smoothly handles digitally signed documents, large files, and complex forms without unexpected crashes.
- 1. Download the software: Download and install WPS Office on your Windows or Mac computer.
- 2. Launch the PDF tool: Open the WPS Office suite and click on 'PDF' from the main dashboard to launch the built-in reader.
- 3. Open your file securely: Click 'Open', locate your digitally signed PDF file, and view it securely without worrying about the app closing automatically.

Frequently Asked Questions
Why do my digitally signed PDFs close automatically?
Digitally signed PDFs (like those from DocuSign) often require background signature validation upon opening. If the PDF viewer's strict security sandbox interferes with this validation process, or if the software is outdated, it may crash or force-close the document to prevent errors.
Does disabling Protected Mode pose a security risk?
Yes, Protected Mode sandboxes PDF files to prevent malicious code or scripts from executing on your computer. You should only disable it temporarily to troubleshoot whether it is causing the PDF to close, and you must re-enable it immediately afterward.
How can I stop my PDF reader from crashing upon opening files?
Start by updating your software to the latest version. If it still crashes, try opening the file from a local hard drive instead of a shared network folder, updating your operating system, or trying a lightweight alternative reader like WPS Office.
