Fix: System Error “EXCEPTION ACCESS VIOLATION”

The “Exception Access Violation” error occurs when a third-party application tries to access protected memory areas it is not allowed to access. This often happens when the application does not have sufficient permissions for reading and writing while accessing these memory areas.

If we look deeply, the error indicates that a certain part of the application code has tried to access memory it was not permitted to do. This can be caused by an outdated application version, corrupted system files, or a virus or malware.

After deep research on this error, we have reached some of the best methods that will surely fix this error.

1. Turn on Data Execution Prevention (DEP)

DEP, or Data Execution Prevention is a security feature that is used to prevent the applications from running the code in the memory areas. DEP works by marking certain areas as non-executable, meaning that the code cannot be executed from those marked areas. Since the error triggers when the application executes code in memory areas, we can try to prevent it by enabling Data Execution Prevention. To do so, follow these steps:

1. Press the Win key to open the Start Menu.
2. Here, search Advanced System Settings and hit Enter to open the settings.
   
3. Now click Settings under Performance.
4. Then, click the Data Execution Prevention tab from the top.
5. Select Turn on DEP for all programs and services except those I select and click Add.
6. Navigate to C Drive > Program Files (x86) > Wise > Wise Programmer Uninstaller.
7. Here, select the WiseProgrammerUninstaller.exe and click Open.
8. Then, click Apply and click OK.
   
9. Restart your PC to save the changes.
10. Once done, verify if the error is fixed.

2. Repair the System Files

Corruption in the System Files, especially the DLL files, can also lead to the exception access violation error message. Therefore, we recommend restoring the system files using the SFC command, which might help you get rid of this error.

SFC or System File Checker is a command line utility that scans the protected system files and restores the corruption by replacing the corrupted files from the cached.

To run the SFC command, follow the steps:

1. Click the Start Menu and type Command Prompt.
2. Right-click the Command Prompt and select Run as administrator.
   
3. Now type sfc /scannow and hit Enter to execute the command.
4. Wait for the verification process to be completed.
   
5. Once done, check whether the error persists or not.

3. Scan for Malware

In most cases, malware or a virus tries to access memory areas. Since you keep getting this error, it is advisable to scan your Windows using either third-party antivirus software or the built-in Windows antivirus software. We recommend using the Windows Defender to scan your system. To do so, follow the steps:

1. Open the Start Menu by pressing the Win key.
2. Here, type Windows Security and hit Enter to navigate.
   
3. Select Virus & threat protection settings.
   
4. Click Scan options to view more scanning features.
   
5. Select the Full Scan option, and click Scan now.
   
6. Wait for the scanning to be completed.
7. Once done, if the Windows Defender detects any suspicious file, it will automatically quarantine it.

4. Disable User Account Control

UAC or User Account Control is a security feature that is used to prevent unauthorized changes by third-party applications. When UAC is enabled, it prompts users for administrator privileges. To be honest, it is very risky to turn off UAC as some third-party applications or malware might take advantage of this to get unauthorized access to the memory areas.

However, if you trust the application or if the application is verified by Microsoft or any other trusted company, you can turn off the UAC. To do so, follow the steps:

1. Click the Start Menu and type User Account Control.
2. Hit Enter to get into the UAC settings.
   
3. Here, you will see the slider; move it all the way down and click OK.
   
4. Click Yes when asked for the administrator privileges.
5. Once done, check if the error is resolved or not.

5. Reinstall the Program

You can also try reinstalling the program if the error persists. The problem with the application’s files often leads to this error. Therefore, if you haven’t tried reinstalling the program yet, give it a try. But make sure to remove all the files related to the application, including the configuration files. To do so, follow the steps:

1. Open the Run Program by using the shortcut combination of Win + R.
2. Type appwiz.cpl in the input box and click OK to navigate into the control panel.
   
3. Here, double-click the application that you want to uninstall.
   
4. Once done, open the Run Program by pressing the Win + R keys.
5. Here, type appdata in the box and click OK.
   
6. Go to the Local folder and remove the application’s folder if found.
   
7. Once done, go to the official website of the application.
8. Download the application installer to install the application.

6. Use the System Restore utility or Reset your Windows

If you are familiar with the System Restore utility and you have created a restore point in the past, we recommend you utilize that restore point to go back to the previous state.

System Restore is a troubleshooting utility that is used to back up the system files in case anything bad happens. However, this method requires a restore point, but if you don’t have it, then you can move on to reset your Windows without losing the data. If your plan is to reset or reinstall Windows, you can follow the steps composed in the articles.

To use a restore point, follow the steps:

1. Press the Win + R keys simultaneously to open Run Program.
2. Type rstrui in the input box and click OK to run the utility.
   
3. Click Next to proceed.
4. Then, select a Restore Point and click Next.
   
5. Click Finish to restore Windows.

In this ultimate guide, we have provided all the methods that could fix this error. However, if the issue persists, it is recommended to inspect your RAM properly to find out whether it is causing the error or not.
