This can be remedied, however, based on the underlying cause. These fixes might just help you:

1st Fix: Using System File Checker

According to Aileen Alf, a Microsoft Agent and forum moderator at the Microsoft Community Forum, you have to check for any files in the Windows system that may have been corrupted. The System File Checker (SFC) can help you to scan for corrupt files, and if there appears to be a problem, the system files will be replaced with a cached version originating from the PC.

To do this, you simply have to follow these steps:

  1. Go to your Start menu and type command prompt
  2. Once the Command Prompt option appears, right-click on it then select Run as administrator. This will open an elevated command prompt with administrative rights.
  3. At the command prompt, type sfc /scannow (note the space between sfc and the /). Wait for a few minutes for the scan to complete (this may vary depending on your system).
  4. If SFC discovered any corrupted files, it will replace them.
  5. Then, restart your PC then check if the issue has been fixed or not.

2nd Fix: Fixing an Access Violation Error

According to Jonny Lin of DriverEasy, this kind of error happens if a program being run is going after a location that had not been assigned to it. There are ways to troubleshoot the problem. You can either:

a. Run the security software to look for any malware which can cause the error. Afterward, run a virus scan to determine if there is a need to do more troubleshooting.

b. Deactivate the affected program’s Data Execution Prevention (DEP), which is a feature intended to protect your computer. This feature can be incompatible with some programs, thereby leading to the error. To disable the DEP, here are the steps you should follow:

  1. Log in as Administrator.
  2. Open the Run window by pressing Windows key and R simultaneously.
  3. In the Run window, type sysdm.cpl then hit Enter.
  4. Go to the Advanced tab, then click on the Settings button under the Performance section.
  5. Head to the Data Execution Prevention tab then select the “Turn on DEP for all programs and services” option. Click Add afterward.
  6. Look for the problematic .exe files and click OK.

c. If the problem lies with a corrupted Registry, restore it or check its entries and remove any entries deemed redundant. One problem with this approach is the complexity behind the work. There could be some unintended consequences that could potentially harm the Registry. You should ask an expert to help you in order to do so.

d. An incompatible Random Access Memory (RAM) can cause the problem. It can be remedied by cutting the power from the computer and removing the RAM to replace it. Prior consultation is needed before proceeding, as this approach requires the disassembly of your computer.

3rd Fix: Resolving a Problematic Startup

There might also be problems when you attempt to start up an application and it crashes, displaying a message that says “The application was unable to start correctly.” Jonny Lin of DriverEasy also offers some tips on how to fix this sort of problem:

a. There might be malware causing the problem. Scan the computer to root out the cause. At times, it could also be due to security software. Perhaps disabling it might show some change.

b. The error could also be due to improper modification on the registry. Restoring the registry to a backup helps, but you can always search for an entry that has been defective and repair it with help from an expert. Before performing any modification, try to back up the Registry to ensure no untoward changes take place.

c. There might have also been changes on the computer that are inconsistent with the operating system which started to cause bugs. In some cases, it could be due to an installation of a different application that caused the 0xc0000005 error. The application can be uninstalled, but if you are unconvinced that this is the cause of the problem, then you will need to run a System Restore You can choose to undo the changes or perhaps uninstall the program to fix the error. To do this, follow these steps.

  1. Click the Start button then type “restore“.
  2. Click on System Restore from the results.
  3. In the Wizard, follow what it says on how to find a restore point. From there, you can complete the restoration process.

d. There might be some issues with the Boot Configuration Data. To fix the Boot Configuration Data, you will need to do the following:

  1. Set up Windows installation media on your computer. Start your computer using the media. A Setup window will pop up on the screen.
  2. Open Command Prompt in the media. If you are a Windows 10 user, click Next and then Repair computer. Afterwards, troubleshoot it and open the Command Prompt.
  3. In the Command Prompt, type the following lines. Make sure you press Enter for every line:
  • del d:\windows\system32\xntkrnl.exe
  • del d:\windows\system32\xosload.exe
  • del d:\windows\system32\drivers\oem-drv64.sys
  • attrib c:\boot\bcd -h -r –s
  • ren c:\boot\bcd bcd.old
  • bootrec /rebuildbcd
  1. Close the Command Prompt window and restart your computer. Once you’re done, check to see if you get rid of the error.
