#1 What is error 0xc000005 and why does it occur?

Error code 0xc0000005 primarily occurs due to access violation. Sometimes, when a user tries to launch a program, this error appears if Windows fails to configure and handle the data required to start that particular program correctly.

Users of Windows 11 might encounter this error on an installer or with installed programs, which can eventually lead to the operating system failing to run correctly.

This error might be related to several factors, such as registry corruption caused by viruses or malware, leading to abnormal program execution. It could also be due to incorrect hardware drivers within the system, or interference from third-party antivirus software that affects the execution of executable files, which could be the main cause of the error.

The error message might display one of the following three lines:

• Windows installation errors
• Application fails to start properly
• Access violation error

The only way to close the error box is by clicking “OK,” and you cannot continue using the program. We'll go over some simple ways to fix these issues.

Fixing Windows Installer Errors

When encountering installation errors while attempting to install Windows, a likely culprit is damaged installation media. You can try reinstalling the program as a potential solution, and if that isn't sufficient, follow these strategies.

Run the tool "Partition Master" to delete and recreate the Windows partition on the hard disk

A corrupted partition created on the hard drive is a primary source of the 0xc0000005 error during OS installation. You can fix the 0xc0000005 error by deleting and recreating the partition.

The point of deleting a partition is to create unallocated space for another hard drive area. The partition master tool can help delete partitions in Windows 11 and most Windows servers.

To delete a partition or all partitions from a Windows hard drive, you need to run the "Partition Master" tool on your system and select the partition you want to remove from the hard disk. Right-click on the partition you wish to delete and choose "Delete." Make sure to back up any important data on the selected partition since the information on it will be completely erased.

Step 1: Launch AOMEI Partition Assistant and click "Manage Partition".

Before deleting any partitions on a disk, make sure you have backed up important data.

Step 2: Select to delete a partition on the hard drive or delete all partitions.

• Delete a Partition: Right-click the partition you want to delete, and then select "Delete."
• Delete All Partitions: Right-click the hard disk where you want to delete all partitions, and then select "Delete All."

Step 3: Click OK to confirm the deletion.

4. Click on "Run xx Task", then click "Apply" to save the changes.

0:00 - 0:26 Remove a single volume; 0:27 - 0:53 Remove all partitions.

Run the Windows Memory Diagnostic

Hardware failures can cause errors during a Windows install. You'll need to run the Windows Memory Diagnostic to check for bad RAM. The benefit of running this is that it helps determine whether the installation error is caused by a hardware or motherboard failure. The Memory Diagnostic will scan and display which components of your computer's memory are failing.

Click on “Control Panel,” then choose “System and Security.” Under “ Administrative Tools,” double-click the “Windows Memory Diagnostic” shortcut. Select “Restart now,” and let it scan for errors.

The system will restart and begin the memory diagnostic immediately. After the test completes, use Event Viewer to examine the results. If there are no errors, you can rule out memory as the cause of the problem.

However, if any errors turn up, you'll need to run deeper memory tests. If the problem persists, it's likely that one of your RAM modules is faulty and needs to be replaced.

Solving "Application Failed to Start" Issues

When you attempt to launch an application installed on your computer and encounter the error, "Application failed to start correctly (0xc0000005)," this could be due to incomplete, invalid, or unsigned DLL files that the software relies on while running on the Windows operating system. The issue can often be resolved by reinstalling the application or repairing the registry.

"Reinstall the application"

A seamless approach to resolve the program error 0xc0000005 when running an application is to reinstall the software. This issue could arise from an improper installation or compatibility problems with Windows, so reinstalling the application might effectively solve the problem.

"Repair the registry"

A corrupted Registry file can cause serious issues with your Windows system, and fixing it isn't a delicate process, since making a mistake can have severe consequences for your system files. If you have a backup of your Registry files, you can use that to solve the problem. Otherwise, create a backup before making any changes.

Please follow the steps below to repair the registry:

1. Press Windows + R, then type Regedit and hit Enter.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\microsoft\windowsNT\CurrentVersion\windows\LoadAppInit_DLLs.
3. Double-click LoadAppInit_DLLs and change the value from 0 to 1.
4. Click OK to confirm the changes, then close the window.
5. Restart your system.

Please verify if the error still appears when trying to enable the application. Proceed with caution with this method, as invalid input can damage your files.

Resolving Access Conflict Exception Errors

The “Access Violation Error” usually occurs when a program in the Windows system fails to handle settings or files correctly. This error is typically caused by issues in the registry, RAM, or elsewhere.

To resolve this issue, you can turn off DEP or run SFC.

Turn off Data Execution Prevention (DEP)

DEP safeguards memory and prevents viruses or malware from corrupting files. However, programs incompatible with DEP can trigger error 0xc0000005. Follow this guide for a fix:

Error 0xc000005 can be prevented by installing an efficient antivirus software, disk monitoring system, scheduling CHKDSK scans, and running FAM diagnostics regularly. These steps should help you eliminate the recurring violation error on your computer.

Press ⊞ Win+R, type system.cpl, and press ↵ Enter.

Click the "Data Execution Prevention" tab.

• Choose "Turn on DEP for all programs and services except those I select."
• Click Add, then browse to the file that might be causing the error.
• Click OK, then restart your computer.
• Run the System File Checker (SFC)
• The System File Checker, or SFC, looks for and replaces corrupt files on your PC. The SFC can help fix the 0xc000005 error. You run it like this:
• Type Command Prompt into your Taskbar search.
• Select "Run as administrator."

4. Type sfc /scannow (there's a space before the slash, but not after it), and press Enter.

• Scan will start automatically
• After scanning, corrupted system files will be detected and replaced

Final Thoughts

Error 0xc000005 can be prevented by installing an efficient antivirus, disk monitoring system, scheduling CHKDSK scans, and regularly running FAM diagnostics. Following these steps should help you eliminate the recurring violation error on your computer.
