Causes of 0xc0000005 Exception Code

The exception code 0xc0000005 isn't an uncommon error on Windows OS; there is no reason to panic. When the error appears, your system can become sluggish, programs or the OS can crash, and you can face frequent system boot errors. These issues can put your system at stake, and you could face data loss.

The 0xc0000005 error code can appear for three reasons. The three types of issues that cause the exception code 0xc0000005 are:

  • Access violation error
  • Application error
  • Windows installation error

An Access violation error occurs when you try to open an app and it's trying to reach a location that isn't assigned for it.

The second cause of the exception code 0xc0000005 is when your app isn't starting correctly. You can repeatedly try to run a program, but it keeps crashing, showing the "The application was unable to start correctly 0xc0000005" message. As with the previous issue, viruses or registry errors can cause it. It's a common but fixable problem.

The third possible cause of the 0xc0000005 error code is the Windows update error. If your Windows update installation fails, you can face several issues with the system. One of them is the exception code 0xc0000005.

How to Fix the 0xc0000005 Exception Code

Various reasons can cause the exception processing message 0xc0000005 – unexpected parameters. While it's relatively common, it's also easy to fix. You don't have to worry if the exception code 0xc0000005 keeps popping up on your screen.

We've prepared nine proven ways to help you fix the issue. With our step-by-step instructions, you'll resolve the 0xc0000005 problem and quickly return your computer to normal.

Run a RAM Windows Memory Diagnostic

A primary reason for the 0xc0000005 exception code is RAM corruption. You can quickly check if your memory is corrupted with the Windows Memory Diagnostic tool, a built-in Windows feature that allows you to identify possible RAM issues.

Follow these steps to check your RAM with the Windows Memory Diagnostic utility:

  1. Press the Windows key and search for Windows Memory Diagnostic in the search bar.
    search for windows memory diagnostic
  2. When you open it, a prompt will appear. Select the Restart now and check for problems option.
    run ram windows memory diagnostic
  3. Your computer will reboot and start scanning. Once the scan finishes, you can see the results on the screen. If your RAM has any issues, follow the on-screen instructions to fix them.

Do a Registry Repair

The exception code 0xc0000005 can appear if your Registry is corrupted. If that's the cause of the error message, you should fix the Registry.

However, fixing the Registry is a challenging task. If the Registry repair goes wrong, you can severely damage your files and computer. Therefore, we suggest you back up your Registry before continuing.

If you want to do a Registry repair to fix the 0xc0000005 problem, follow these steps:

  1. Open the Run dialog box by pressing Win + Run. Type regedit and press Enter.
    open the registry editor
  2. That will open the Registry Editor. Now follow this path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\LoadAppInit_DLLs. Double-click LoadAppInit_DLLS and change the value from 0 to 1.
    change data values in the registry
  3. Click OK and reboot the system.

Run an SFC Scan

The System File Checker, or SFC, allows you to scan and replace damaged or corrupted system files with healthy ones. If corrupted, missing, or outdated system files caused your 0xc0000005 problem, you can fix it by repairing them. An SFC scan is a quick solution; the best part is it's available in your Windows system by default.

Follow these steps to run an SFC scan:

  1. Press the Win key, search for the Command Prompt (or CMD), and select Run as administrator.
    open the command prompt
  2. That will open the Command Prompt window. Type sfc/scannow in the command line and press Enter.
    scan the system in the cmd
  3. Wait for the process to complete. Once you finish scanning your system, close the Command Prompt and restart your computer.

Run CHKDSK

CHKDSK is a utility that allows you to fix errors and delete partitions. If you delete a partition, it's good to have a backup of your hard disk to recover lost files. If your 0xc0000005 problem appears due to a faulty or corrupted hard drive, a CHKDSK scan can help highlight bad sectors and resolve the problem.

Follow these steps to run the CHKDSK command:

  1. Search for the Command Prompt and select Run as administrator.
  2. Type chkdsk X: /f /r in the command line and press Enter. Replace the X parameter with the corrupted hard drive's letter.
    run the chkdsk command
  3. Let the scan complete the process and exit the Command Prompt. Then, check if the 0xc0000005 issue is gone.

Turn off Data Execution Prevention

Data Execution Prevention, or DEP, is a built-in feature of Windows that protects your system from security threats and damages due to viruses. The DEP feature is valuable for protecting your data and system. However, not all programs are compatible with DEP.

If Data Execution Prevention is enabled on your PC when you try to run some apps, the error message 0xc0000005 can appear.

To turn off Data Execution Prevention on your computer, follow these steps:

  1. Press the Windows key and ..
  2. Type sysdm.cpl in the dialog box and press Enter.
    open system properties
  3. That will open the System Properties. Go to the Advanced tab and select Settings.
    open settings from the advanced tab
  4. Click the Data Execution Prevention tab. Tick the checkbox next to Turn on DEP for all programs and services except those I select.
    turn off dep for specific programs
  5. Click Add, select the program you can't open, and hit OK.
    select the problematic program
  6. Once you add the problematic app, click OK. Your 0xc0000005 problem should be gone.

Scan Your Device for Viruses

Viruses and other malware are among the most prevalent causes of the exception code 0xc0000005 error. If a virus infects your computer, you can scan and clean it with the built-in antivirus utility.

Microsoft Defender Antivirus is an ingrained Windows tool that scans your system and removes malicious software in a few steps.

Follow these steps to remove potential viruses from your system using Microsoft Defender Antivirus:

  1. Press the Windows key and search for Windows Security.
    open windows security
  2. Then, select Virus & threat protection.
    select virus and threat protection
  3. Scroll down and click Scan options.
    open scan options
  4. Choose the desired scan type. A Full or Microsoft Defender Offline scan will check your system for more difficult-to-remove malware.
    choose a scan type
  5. Click Scan now and wait for the antivirus program to check your system for viruses. Once the process is done, restart your computer and follow the on-screen instructions to remove the virus.

Update Disk Drivers

One cause of the exception code 0xc0000005 is outdated drivers. Obsolete drivers can cause numerous issues with system performance, including the 0xc0000005 error code. However, you can update them to resolve the problem.

To update your disk drivers, follow these steps:

  1. Press Windows + X and select Device Manager.
    open device manager

    search automatically for drivers

Reinstall the App You're Trying to Run

If you can't run a program and the error message "The application was unable to start correctly 0xc0000005" appears, you can reinstall the app. Reinstalling the app can fix the error and allow you to use it properly. This process can help if compatibility issues exist or if the app was installed incorrectly.

    allow the app to make changes

When you perform a factory reset, you delete all your apps, settings, and files. Therefore, back up your files before doing it.
