How to Fix Adobe Acrobat Not Responding? 11 Fixes 2025

Part 1. Why Is Adobe Acrobat Not Responding/Keeps Freezing

Adobe Acrobat and Reader becoming unresponsive on a daily basis usually points to common system or file-related problems. Acrobat is a powerful tool, but even small conflicts can cause it to freeze, hang, or crash. Below are the main reasons why Acrobat stops responding:

1. Large or Complex PDF Files

Heavy PDFs with high-resolution images, layered graphics, or hundreds of pages take longer to load, causing Acrobat to freeze or slow down.

2. Outdated Adobe Acrobat Version

Running an older version often leads to instability and known bugs that make the app unresponsive.

3. Corrupted or Damaged PDF Documents

If the file you’re opening is broken or incomplete, Acrobat may crash while trying to process it.

4. Conflicts with Antivirus or Security Software

Security tools sometimes block Acrobat’s processes, leading to freezing, long loading times, or automatic shutdowns.

5. Hardware Limitations (Low RAM or Slow Hard Drive)

Systems with low memory or older HDDs struggle to handle Acrobat’s processing, especially with large documents.

6. Broken Installation or Outdated Drivers

Incomplete installation files, old GPU drivers, or recent Windows updates can disrupt Acrobat’s performance.

7. Too Many Plug-ins or Problematic Add-ons

Extensions that are outdated or incompatible often cause Acrobat to freeze during launch or while opening PDFs.

8. A Running Instance of Acrobat in the Background

Sometimes a previous Acrobat session remains active in the background, causing errors when you try to open the app again.

2. Restart Adobe Acrobat

Sometimes, Acrobat freezes due to temporary glitches or background processes that get stuck. Restarting the application or the system can clear these minor errors.

• Close Adobe Acrobat completely. Make sure no PDF files remain open.
• Open Task Manager (Windows: Ctrl + Shift + Esc | Mac: Activity Monitor).
• Look for any processes named Acrobat.exe, AcroRd32.exe, or Adobe Acrobat DC.

• Select each process and click End Task (Windows) or Quit Process (Mac).
• Restart Adobe Acrobat and try opening your PDF again.

3. Clear Recent Files

Corrupted or problematic entries in Acrobat’s Recent Files list can cause the program to freeze immediately upon launch. Clearing the list can prevent repeated crashes.

• Open Adobe Acrobat. Go to File > Open Recent.
• Click Clear Recent File List (or Clear Recent Documents on Mac).

• Close and reopen Acrobat.

Tips:

After clearing, try opening PDFs stored locally on your computer first, rather than network drives, to avoid conflicts that can trigger Adobe not responding errors.

4. Check for Updates

Outdated versions of Acrobat are a common reason for Adobe DC not responding, as older builds may contain bugs that Adobe has already patched. Even if your Creative Cloud shows the software as updated, a manual check often finds optional updates that fix freezing issues.

• Open Adobe Acrobat. Navigate to Help > Check for Updates.

• If an update is available, click Download and Install.
• After updating, restart your computer to ensure changes take effect.

5. Run as Administrator

On Windows, restricted permissions or conflicts with security software may prevent Acrobat from accessing certain system resources, causing it to freeze. Running Acrobat as an administrator ensures it has the necessary access.

• Right-click the Adobe Acrobat shortcut on your desktop or Start Menu.
• Select Run as Administrator.

• Open your PDF and test performance.

Optional Step: For a permanent fix, you can set Acrobat to always run as administrator:

• Right-click the Acrobat shortcut, select Properties, then go to the Compatibility tab.
• Check Run this program as an administrator and click Apply.

Part 3. How to Fix Adobe Not Responding/Keeps Freezing – Deeper Troubleshooting

If the basic fixes did not solve the problem, it’s time to move on to deeper troubleshooting. Many users experience Adobe Acrobat freezing, or sudden hangs while opening or editing PDFs. Below are six advanced methods to resolve these problems effectively.

1. Repair Installation

A corrupted or incomplete installation of Acrobat is one of the most common reasons for Adobe Acrobat not responding. Using the built-in repair function can replace missing or damaged files without requiring a full reinstallation.

• Open Adobe Acrobat. If it’s currently frozen, close it completely using Task Manager (Windows) or Activity Monitor (Mac).
• Navigate to the Help menu at the top of the application window.
• Select Repair Installation from the dropdown menu.

• Follow the on-screen instructions carefully. The repair process may take several minutes depending on your system.
• Once the repair is complete, restart your computer to ensure all repaired files are properly loaded.

2. Reset Preferences

Corrupted preference files can cause repeated freezing, slow responses, or unexpected crashes in Acrobat. Resetting preferences restores all default settings without affecting your PDF documents.

• Make sure it is not running in the background (use Task Manager on Windows or Force Quit on Mac if needed).
• This opens the Reset Options dialog, allowing you to choose what you want to reset.
• Choose the reset options you want:
• Reset app preferences: Restores Acrobat’s default settings and removes custom workspaces or watch folders.
• Reset user presets: Deletes saved presets and forces Acrobat to rebuild them.
• Reset plugin loading cache: Clears cached plugin data that may be causing freezing.
• Disable third-party plugins (temporary): Helps identify if a plugin is causing Acrobat to hang.

• Acrobat will restart using your selected reset choices.
• If the app still freezes, repeat the reset process or try disabling suspicious plug-ins one by one.

3. Disable New Acrobat

Many users report that the latest updates introduce new templates, tools, or interface changes that can cause Acrobat to freeze. Disabling the new UI or features often fixes Adobe Acrobat DC not responding problems.

• Open Acrobat. If it doesn’t open normally, try Run as Administrator (explained in previous steps).
• Click the Menu in the top-left corner of the window.
• Look for the option Disable New Acrobat or Turn Off New Features, depending on your version.

• Click the option, confirm any prompts, and close Acrobat.

4. Check Storage & System

Insufficient system resources or low disk space can make Acrobat freeze, especially with large or complex PDFs. Ensuring your system has enough free space and memory helps prevent Adobe Acrobat freezing issues.

• Check your system drive (usually C:) and make sure there is at least 10–15% free disk space.
• Open Task Manager (Windows) or Activity Monitor (Mac) and monitor RAM and CPU usage. Close unnecessary applications consuming high resources.
• If your computer has limited RAM, avoid opening multiple large PDFs simultaneously.

5. Disable Plugins/Extensions

Third-party plugins, extensions, or add-ons can sometimes conflict with Acrobat, causing crashes or slow performance. Disabling unnecessary plugins often resolves Adobe Acrobat DC not responding errors.

• Open Acrobat. Go to Edit > Preferences > Plug-Ins or Extensions (depending on your version).

• Review the list of installed plugins. Identify and disable any that you do not use or that may be outdated.

6. Use the Cleaner Tool

If all other steps fail, a full cleanup and fresh installation may be required. Adobe provides a Cleaner Tool to completely remove Acrobat and all related files, ensuring no residual or corrupted data remains.

• Close Acrobat completely and ensure no background processes are running.
• Download the Adobe Acrobat Cleaner Tool from Adobe’s official website.

• Run the tool and follow the instructions to remove all traces of Acrobat from your system.
• Restart your computer after the cleanup is complete.
• Reinstall Acrobat using the official installer from Adobe’s website.
