Fully Close and Relaunch the App

When you have trouble using an app, fully quit and relaunch the app to possibly fix your issue. Doing so resolves many minor glitches with your application, allowing you to load your app without problems.

2. Access the Processes tab in Task Manager
3. Find and right-click your faulty app on the list and choose End task.

Run the App With Admin Privileges

If your app still fails to launch, your app may be lacking the required permissions to function. In this case, give your app all the permissions it needs to run by launching the app as an admin.

1. Locate your app in your Start menu or on your desktop
2. Right-click the app and choose Run as administrator

3. Select Yes in the User Account Control prompt

If your app launches in admin mode, configure a setting option so Windows always opens your app with admin rights. This saves you from having to run the app as an admin manually every time.

1. Right-click your app shortcut on your desktop and choose Properties
2. Access the Shortcut tab in Properties
3. Select the Advanced tab
4. Enable the Run as administrator option and choose OK.

5. Select Apply followed by OK.

From now on, you can double-click your desktop app shortcut to launch your app with administrative privileges.

One reason your app fails to launch and Windows displays a 0xc0000005 error is that your app isn’t compatible with your operating system version.

1. Right-click your app on your desktop and choose Properties
2. Access the Compatibility tab and choose Run compatibility troubleshooter

3. Allow the troubleshooter to detect and resolve issues with your app.

Your computer’s RAM issues can cause your applications not to launch. This is because your apps store their temporary data on your PC’s volatile memory, also known as RAM, and these memory issues can cause your apps not to store their data.

1. Open the Start menu by selecting the Start button or pressing the Windows key, find Windows Memory Diagnostic using the search box, and launch the tool.

A virus or malware infection can cause Windows and your installed apps to malfunction. Your app not launching and displaying a 0xc0000005 error may be the result of an infected computer.

1. Open the Windows Security app on your PC.
2. Select Virus & threat protection in the app.
3. Choose Scan options on the following page.

Corrupted system files can break your PC’s various features and even cause your installed apps not to launch. This is because a corrupted file doesn’t let your operating system run correctly. This may be why you’re having trouble launching your app.

1. Open Start, find Command Prompt, and select Run as administrator.
2. Choose Yes in the User Account Control prompt.
3. Type the following command on the CMD window and press Enter: DISM.exe /Online /Cleanup-image /Restorehealth
