- Device & OS
- not provided
- Scenario
- Opening, viewing, or editing PDF files.

Update Software and Adjust Security Preferences
Installing the latest updates and temporarily disabling security features like Protected View can quickly resolve performance conflicts.
Acrobat may freeze if it encounters conflicts with system security settings or runs on an outdated version. Disabling Protected View helps identify if the security sandbox is causing the stall.
Open Acrobat Pro DC, navigate to the 'Help' menu at the top, and click on 'Check for Updates'. Follow the on-screen prompts to install any available patches.
Go to 'Edit' > 'Preferences' > 'Security (Enhanced)'. Under 'Sandbox Protections', turn off 'Protected View' and uncheck 'Enable Enhanced Security'. Restart Acrobat and test.
While in the 'Preferences' menu, navigate to 'General' or the specific plug-in settings and temporarily disable third-party plug-ins to see if performance improves.
Reset Acrobat Preferences and Clear Temporary Files
Corrupted preference files or an overloaded system temporary folder can cause the application to hang or become unresponsive.
Repair Installation and Check Printer Drivers
A damaged installation or conflicts with an outdated default printer driver can cause continuous polling delays that freeze the application.
Use WPS PDF to View and Edit PDFs Without Freezing

Frequently Asked Questions
Why does Acrobat Pro DC keep saying "Not Responding"?
This status typically appears when the software is waiting on a blocked process, such as loading a heavily unoptimized PDF, resolving a network path, dealing with conflicting third-party plug-ins, or trying to communicate with an outdated printer driver.
How do I repair my Adobe Acrobat Pro DC installation?
On Windows, you can repair your installation by opening Acrobat, navigating to the 'Help' menu at the top, and selecting 'Repair Installation'. Wait for the progress bar to finish and restart your computer.
Can a very large PDF file cause the application to freeze?
Yes, large PDF files—especially those containing high-resolution unoptimized images, complex vector graphics, or those opened directly from a slow network drive—can cause the application to stall temporarily while it loads data into your system's memory.
Will disabling Protected View make my computer vulnerable?
Yes, disabling Protected View lowers your defense against potentially malicious scripts embedded in PDF files. It should only be turned off temporarily to diagnose freezing issues and must be re-enabled once troubleshooting is complete.
