- Scenario
- Launching the Adobe Acrobat application.

Clear AppData and Repair Acrobat Installation
Resetting hidden application data and fixing corrupted program files can frequently resolve access violation errors during startup.
Error 0xc0000005 often translates to 'permission denied'. This can happen when Acrobat attempts to access a corrupted configuration file hidden in your Windows user profile.
Press the Windows key + R on your keyboard simultaneously to open the Windows Run box.
Type %APPDATA%\Adobe into the Run box and press Enter. This will open the hidden directory where Adobe stores user-specific critical files.
Locate the 'Acrobat' folder in the directory. Right-click it and select 'Rename'. Change the name to 'Acrobat_old' to force the software to generate fresh, error-free settings on its next launch.
Open the Windows Control Panel, navigate to 'Programs and Features', locate Adobe Acrobat in the software list, right-click it, and choose 'Change' or 'Repair' to fix any damaged application files.
Analyze the Crash Using Process Explorer
If basic repairs fail, generating a crash mini-dump will help identify the specific system driver, DLL, or process causing the startup failure.

Frequently Asked Questions
What does error code 0xc0000005 mean in Windows?
Error code 0xc0000005 generally indicates an 'Access Violation' or 'Permission Denied'. It occurs when a program attempts to read or write to a memory location that it does not have the correct permissions for, often due to corrupted files, faulty RAM, or incompatible drivers.
Why can't I see the AppData folder when searching for Adobe files?
The AppData folder is designated as a critical system folder and is hidden by default in Windows to prevent accidental modifications. You can access it directly by pressing the Windows Key + R and typing %APPDATA% in the Run dialog.
Can third-party antivirus software cause Acrobat to crash on startup?
Yes, overly aggressive security software can mistakenly block Adobe Acrobat from accessing required system memory or temporary files, resulting in the 0xc0000005 error. Temporarily disabling the antivirus can help identify if it is the root cause.
What is a mini-dump and how does it help fix Acrobat?
A mini-dump is a small diagnostic file that captures the exact state of a program's memory at the moment it crashes. Analyzing this file helps identify the specific corrupted driver, DLL, or background service that is conflicting with Acrobat.
