If when you receive an Unhandled Exception Access Violation error when you run an application on your Windows 11/10/8/7 computer, it probably means that some part of the program code tried to access a protected memory address and was denied access.
What does EXCEPTION ACCESS VIOLATION mean?
When a program tries to access a protected memory address, this error message box can appear. It can also appear if the software has been badly programmed. If access is denied, you see this error message.
Unhandled Exception – EXCEPTION ACCESS VIOLATION
If you receive this error, here are a few things you could try:
1] Disable Data Execution Prevention for that particular program
Data Execution Prevention or DEP is a security feature that can help prevent damage to your computer from viruses and other security threats. DEP can help protect your computer by monitoring programs to make sure they use system memory safely. If a program tries running (also known as executing) code from memory in an incorrect way, DEP closes the program.
So if you trust the program that is throwing up this error, you may turn off Data Execution Prevention for this particular program and see if it works for you.
2] Run the Hardware Troubleshooter
Open Run box, type the following and hit Enter to open the Hardware & Devices Troubleshooter:
%systemroot%\system32\msdt.exe -id DeviceDiagnostic
The Hardware and Devices Troubleshooter will try to identify potential issues with your computer hardware and fix them if possible.
3] Turn off UAC
Temporarily turn of UAC and see if that helps.
4] Reinstall the program
You may also want to consider the option of completely uninstalling the software that throws up this error when run, and reinstall it. Make sure that you download the latest version from its official home page.
Hope something helps!
