Oftentimes, a malware infection may be responsible for the Exception Access Violation error. To determine if this is the case, run the Windows Defender or any third-party antivirus program to scan for malware.

To run the Windows Defender, follow these steps:

  • Go to the “Start” menu.
  • Type “Windows Security” in the search bar and press ‘Enter’.
  • Go to “Virus & Threat Protection” settings.
  • Select “Scan Options” and then click on the “Full Scan” option.

Method 2: Check for Faulty RAM Modules

If your PC has faulty or improperly placed RAM modules, it can trigger the “Exception Access Violation” error on your PC. To fix that, check the RAM modules on your PC physically. Make sure that they are fixed properly and that the pins are not damaged.

You should also run the Windows Memory Diagnostic tool to check whether the memory modules are functioning properly. 

To do so:

  • Press the ‘Win + Q’ keys on your keyboard and search for the “Windows Memory Diagnostic” tool.
  • Click on “Run as administrator” to launch the “Windows Memory Diagnostic” tool.
Type Windows Memory Diagnostic
  • Now hit the “Restart now and check for problems (recommended)” option.

If the tool finds any errors, make sure to fix them by running the Auto troubleshooter. Once the errors have been removed, restart your PC and check whether the issue has been resolved.

If the issue persists, try other fixes mentioned below.

Method 3: Turn Off the User Account Control (UAC) Settings

When you have the User Account Control (UAC) settings turned on on your PC, they can trigger the Exception Access Violation error on your PC. Simply disabling the UAC settings on your PC can fix it.

Here’s how to do it:

  • On your keyboard, press the ‘Win + Q’ keys and search and launch the “Control Panel”.
Press Windows + Q and Search for Control Panel
  • Now go to “Security and Maintenance”.
  • Go to the “Change User Account Control” settings in the left sidebar.
  • Slide the slider down to “Never Notify”.
  • Now hit the “OK” button to save the changes made.
Slide the slider down to Never Notify
  • Finally, restart your computer to put the changes into effect.

Note: When you disable UAC, it could pose a security risk. So make sure to only disable the UAC settings temporarily. Once you have carried out the intended function, enable the UAC settings.

If the issue persists, try the advanced fixes mentioned below.

3 Advanced Ways to Fix the “Exception_Access_Violation” Error

As promised, let’s see some of the more advanced solutions suitable for more tech-savvy users.

Adv. Method 1: Add the Affected App to the Data Execution Prevention (DEP) Exception Feature

Download Fix Now iolo's System Mechanic® will automatically fix your Exception Access Violation issues, optimize & protect your whole PC.

The Data Execution Prevention (DEP) feature in Windows 10 and Windows 11 is a security feature that prevents certain codes (usually malicious) from executing. As a result, it triggers the “Exception Access Violation” error. 

To prevent this feature from triggering the error, you can add the affected app or program to the Data Execution Prevention (DEP) exception list.

Here’s how to do it:

  • On your keyboard, press the ‘Win + S’ keys and search for and launch the “Advanced System Settings”.
  • Now navigate to the “System Properties” window, go to the “Advanced” tab > “Performance” section, and click on “Settings”.
System Properties Performance Settings
  • In the resulting “Performance Options” window, go to the “Data Execution Prevention” tab.
  • Now enable the “Turn on DEP for all programs and services except for those I select” option.
  • Next, select “Add” and search for the “.exe” file of the problematic application that you intend to run. 
  • Select “Open”.
  • After selecting the application, hit the “Apply” and “OK” buttons in the “Performance Options” window.
Turn on DEP for all programs and services

The desired application will now have been added to the Data Execution Prevention (DEP) exception list. Launch the application now to see if it is running successfully.

If the issue persists, try other fixes mentioned below.

Adv. Method 2: Make Sure That the File Has Both Read and Write Permissions

Oftentimes, the “Exception Access Violation” error is triggered when you are opening a program using its shortcut. If the file has been set to read-only mode, it will not open.

To make sure that the file is not set to read-only mode, you will need to check the properties and change the settings (if needed).

Here’s how to do so:

  • Right-click on the program’s shortcut file.
  • Go to “Properties > General > Attributes”.
  • If the “Read-only” attribute is checkmarked, uncheck the option.
  • Now hit “Apply” and then “OK”.

Run the application file again to see whether the issue has been resolved. If it persists, try the fix mentioned below.

Adv. Method 3: Use Compatibility Mode to Run the Program

If the program you are trying to launch is not compatible with the current operating system, it may run into the Exception Access Violation error. To fix that, you can consider using the program with the “Compatibility” mode.

Here’s how to do so:

  • Right-click on the executable file of the said program.
  • Go to “Properties > Compatibility” tab.
  • Now navigate to the “Compatibility mode” section.
  • Enable the “Run this program in compatibility mode for” option and then choose an ‘OS’ from the drop-down menu.
  • Finally, hit “Apply” then “OK”.

By doing so, you can enable an incompatible program to run in the Compatibility mode and resolve the “Exception Access Violation” error.

However, if none of the above-mentioned fixes work, you can uninstall and reinstall the affected program. You can also disable any plugins that may be triggering this error.
Lastly, you can launch the hardware troubleshooter to identify any underlying hardware problems.
