How to Fix the “Application Has Failed to Start” Error on Windows 11: Step-by-Step Solutions

If you have encountered the “Application Has Failed to Start” error on Windows 11, it can be frustrating. This message usually appears when an app cannot run properly due to missing files or system issues.

Fortunately, there are several straightforward ways to fix this problem. You don’t need to be a tech expert to follow these solutions.

This guide will walk you through simple, step-by-step methods to get your application running again. Each step explains why it’s important and how to do it.

By the end, you should have your app working smoothly or know what to do next if the problem persists.

Quick Note: Before You Start

  • Make sure your Windows 11 is up to date. Sometimes, updates fix compatibility issues automatically.
  • Check if the application is compatible with Windows 11. Older apps might have trouble running.
  • Restart your computer before trying any fixes. This can resolve temporary glitches.
  • Note the exact error message or code, if available. It helps in troubleshooting specific problems.

Step 1: Run the Application as Administrator

Sometimes, apps need special permissions to start correctly. Running as an administrator gives the app these permissions.

  1. Right-click on the application’s shortcut or executable file.
  2. Select Run as administrator from the context menu.
  3. If prompted by User Account Control (UAC), click Yes to allow.

This step helps because some apps require higher privileges to access necessary system files or settings.

Step 2: Check for Missing or Corrupted Files

Many applications rely on system files or specific components to run. If these are missing or damaged, the app may fail to start.

Use System File Checker (SFC) Tool

  1. Press Windows + S and type cmd.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the black window, type sfc /scannow and press Enter.
  4. Wait for the scan to complete. It will automatically fix corrupted system files.

This tool checks Windows system files and repairs them, which can fix app startup problems caused by system errors.

Step 3: Reinstall the Application

If the application files themselves are damaged or incomplete, reinstalling can help.

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps (or Apps > Apps & features).
  3. Find the troublesome application and click the three-dot menu next to it.
  4. Select Uninstall and follow the prompts.
  5. After uninstalling, download the latest version of the app from the official website and install it.

Reinstalling replaces missing or corrupted app files and ensures you have the latest version compatible with Windows 11.

Step 4: Install or Repair Microsoft Visual C++ Redistributables

Many Windows applications depend on Visual C++ Redistributable packages. If these are missing or broken, apps may fail to start.

  1. Visit the official Microsoft website and download the latest Visual C++ Redistributable packages (official link).
  2. Download both the x86 and x64 versions, if your PC supports 64-bit.
  3. Run the installers and choose Repair if the option appears, or complete the installation.
  4. Restart your computer after installation.

This step fixes missing runtime components many apps require to launch and run properly.

Step 5: Disable Third-Party Antivirus or Firewall Temporarily

Sometimes, antivirus software or firewalls block applications from starting. Temporarily disabling them can help identify if they’re causing the problem.

  1. Right-click your antivirus icon in the taskbar and look for an option to disable or pause protection.
  2. Disable the firewall temporarily by going to Windows Security > Firewall & network protection and turning off the active network firewall.
  3. Try running the application again.
  4. If the app starts, add it to the antivirus/firewall exceptions list before re-enabling protection.

Warning: Always turn your antivirus and firewall back on after testing. Do not leave them off permanently.

Step 6: Use Compatibility Mode

If the application is old, it may not fully support Windows 11. Running it in compatibility mode can help.

  1. Right-click on the app’s shortcut or executable.
  2. Select Properties.
  3. Go to the Compatibility tab.
  4. Check the box for Run this program in compatibility mode for:
  5. Select an older version of Windows like Windows 10 or Windows 7.
  6. Click Apply and then OK.
  7. Try launching the app again.

This tells Windows to mimic the environment of an older operating system, improving app compatibility.
