Question details

The user needs to resolve an issue where Adobe Acrobat Reader crashes and closes immediately upon launching or opening a PDF file.

How to Fix Acrobat Reader Crashing with AcroRd32.exe and Shcore.dll Errors
Product
Adobe Acrobat Reader
Device & OS
Windows 10
Scenario
Launching the application or opening PDF documents, especially after a system upgrade to Windows 10.
Observed behavior
Acrobat Reader closes immediately upon opening, and the Windows crash report identifies AcroRd32.exe and Shcore.dll as the failing modules.
Before you start

Verify if your system was recently upgraded to Windows 10 from an older version, as system upgrades frequently cause Shcore.dll conflicts. Save any background work before adjusting system compatibility or Data Execution Prevention (DEP) settings.

Solution 1Recommended

Adjust Compatibility Mode and DEP Settings

Running Acrobat in compatibility mode can bypass Shcore.dll crashes caused by OS upgrades, while disabling DEP prevents Windows from aggressively closing the AcroRd32.exe process.

Windows 10 introduces new display scaling and security features that older software installations might struggle to handle. Forcing the program to run under Windows 7 or 8 compatibility rules often stabilizes the application.

1
Open Compatibility Troubleshooter

Right-click the Adobe Acrobat Reader desktop shortcut and select 'Properties', then navigate to the 'Compatibility' tab.

2
Run in compatibility mode

Check the box next to 'Run this program in compatibility mode for' and select 'Windows 8' or 'Windows 7' from the dropdown menu.

3
Apply and test

Click 'Apply' and then 'OK'. Double-click the shortcut to see if Acrobat Reader launches without closing.

4
Adjust DEP settings

If it still crashes, press the Windows key, search for 'View advanced system settings', go to the 'Advanced' tab, click 'Settings' under Performance, navigate to the 'Data Execution Prevention' tab, and add AcroRd32.exe as an exception.

Adjust Compatibility Mode and DEP Settings
System Reboot Recommended: Restart your Windows 10 computer after changing DEP settings to ensure the new execution rules take effect properly.

Frequently Asked Questions

What is Shcore.dll and why does it cause Acrobat Reader to crash?

Shcore.dll is a Microsoft Windows system file responsible for handling display scaling on high DPI monitors. Conflicts during Windows 10 upgrades or outdated Acrobat versions can cause the AcroRd32.exe process to fail when calling this DLL, resulting in an immediate crash.

Will uninstalling the Creative Cloud desktop app fix the AcroRd32.exe crash?

In some environments, third-party vertical applications or the Adobe Creative Cloud desktop app can conflict with Acrobat Reader's core processes. Temporarily disabling or uninstalling them is an effective troubleshooting step to determine if they are the root cause.

How do I find the Acrobat Reader crash logs on Windows 10?

You can locate detailed crash reports by pressing the Windows Key, typing 'Event Viewer', and opening the app. Navigate to 'Windows Logs' > 'Application', and look for recent 'Error' events that mention AcroRd32.exe or Shcore.dll in the details pane.
