What is Error 0xc000005, and Why is This Error Happening?

Error oxc0000005 is an error that occurs mainly as a result of access violation. Occasionally, when a user wants to start a program, errors appear if Windows cannot configure and process the data it needs to launch that specific program.

Windows 11 users will come across this error on a program installer or on an installed program which will ultimately disband a functional operating system.  

This error is linked to some factors, such as corrupted registries due to viruses and malware, allowing the programs to function abnormally. It can also be that the system's hardware drivers are wrong, and a third-party antivirus program affecting and interfering with the operation of executable files can be a significant reason for the error.

Run Windows Memory Diagnostics

When installing windows, defective hardware can be the bane of the error. You'll need to run a Windows memory diagnostic to check for faults in the RAM. The benefit of running windows memory diagnostics aids in determining if the installation error is occurring due to the hardware or motherboard failure. The memory diagnostics checks and displays the components of the hardware memory failure. 

You can run the diagnostics by simply clicking the "control panel" then select "system and security." Under "administrative tools," just double-click the "windows memory diagnostic" shortcut. Select "restart now" then scan for the errors.

The system reboots and automatically begins the memory diagnostics immediately. Once the test is completed, proceed to check the test result using the event viewer. When there is a lack of error, then you can rule out memory as a problem. 

However, if there is any error, you'll need to run an extensive memory test. If the issue persists, then it may be that one of the RAM modules is problematic and needs replacement. 

Fix "The Application Was Unable to Start"

Whenever you try launching an application installed on your PC and the Error: the application was unable to start correctly (0xc0000005) appears, it may be resulting from some incomplete, invalid, or unsigned DLL files that assist software is running on Windows OS.
