Hi all,
How do I troubleshoot Acrobat not responding or freezing?
If Acrobat stops responding or appears to freeze while opening, viewing, or scrolling through PDF files, follow this structured troubleshooting workflow sequentially until the issue is resolved. Beginning with the supported maintenance steps helps isolate whether the issue is related to the application, the PDF itself, or the local environment before moving to more advanced diagnostics.
Start with these steps, in order:
- Update Acrobat to the latest available version.
- Restart your computer.
- Run Menu > Help > Repair Installation (Windows).
- Test the same PDF again to determine whether the behavior has changed.
If Acrobat responds normally after one of these steps, no additional troubleshooting is typically required. If the issue continues, move to the workflow below.

Should I temporarily disable Protected Mode while troubleshooting?
Protected Mode is enabled by default and is Acrobat's primary sandboxing security feature. Leave Protected Mode enabled during normal use.
As part of troubleshooting, you can temporarily disable Protected Mode to determine whether a compatibility issue is contributing to the behavior. This is intended only as a diagnostic step, not a permanent configuration.
After testing, re-enable Protected Mode so Acrobat continues to benefit from its built-in security protections.
If temporarily disabling Protected Mode changes the behavior, it may indicate a compatibility issue in the local environment. Updating third-party security software, plug-ins, or other components is the recommended long-term solution, rather than leaving Protected Mode disabled.

What if temporarily disabling Protected Mode changes the behavior?
| If the issue is related to... | Recommended next step |
|---|
| Third-party security software | Update the security software and test again |
| Plug-ins or extensions | Update or temporarily remove incompatible plug-ins while testing |
| A specific PDF file | Test with other PDF files to determine whether the issue is document-specific |
| The Acrobat installation | Repair the installation (Windows) or continue with the remaining steps |
The recommended long-term approach is to identify and resolve the underlying compatibility issue, rather than leaving Protected Mode disabled.

What should I do if the issue persists?
If Acrobat continues to stop responding after you've worked through the steps above in order, collect Adobe Acrobat Diagnostics logs while reproducing the issue and share them with Adobe Support.
Acrobat Diagnostics collects product logs, process information, and relevant system information that can help Adobe Support investigate application responsiveness, crashes, and performance related behavior more efficiently.
If the issue still isn't resolved after contacting Support, you can also check or post in the Acrobat community, where other users and Adobe staff may have encountered the same issue.
