1. Restart your computer

Why Restarting Helps: Restarting your computer can resolve many software issues by clearing out temporary files and closing background processes that might be interfering with the app. 

Steps to Restart

  • Click on the Start menu. 
  • Select the Power button. 
  • Click Restart
  • Once your computer restarts, try opening the app again.

2. Run the app as an administrator

Why Running as Administrator Helps: Some apps require administrative privileges to run properly. Running the app as an administrator can give it the permissions it needs. 

Steps to Run as Administrator

  • Right-click on the app’s icon. 
  • Select Run as administrator
  • If prompted by User Account Control (UAC), click Yes
  • Check if the app starts correctly.

3. Update Windows and the app

Why Updating Helps: Keeping your operating system and apps updated ensures you have the latest features and bug fixes, which can resolve compatibility issues. 

Steps to Update Windows

  • Open Settings by pressing Windows + I. 
  • Go to Windows Update
  • Click on Check for updates and install any available updates. 

Steps to Update the App

  • Open the app (if possible) and look for an update option within the app’s menu. 
  • Alternatively, visit the app’s official website to download and install the latest version.

4. Repair or reset the app

Why Repairing or Resetting Helps: Repairing or resetting an app can fix corrupted files and settings that might be preventing the app from starting. 

Steps to Repair or Reset an App

  • Open Settings by pressing Windows + I. 
  • Go to Apps > Installed apps
  • Find the app that won’t start in the list and click on it. 
  • Select Advanced options
  • First, try the Repair option. This will attempt to fix the app without affecting your data. 
  • If repairing doesn’t work, use the Reset option. This will reset the app to its default state, which may result in loss of app data. 
  • After resetting, try opening the app again.

5. Check for corrupt system files

Why Checking for Corrupt System Files Helps: Corrupt system files can interfere with app functionality. Running a system file check can identify and repair these issues. 

Steps to Check for Corrupt System Files

  • Open Command Prompt as an administrator. Press Windows + X and select Windows Terminal (Admin)
  • Type sfc /scannow and press Enter
  • The System File Checker will scan your system for corrupt files and repair them. 
  • Restart your computer and try launching the app again.

6. Check compatibility settings

Why Checking Compatibility Helps: Some older apps might not run correctly on Windows 11 without adjusting their compatibility settings. 

Steps to Check Compatibility Settings

  • Right-click on the app’s icon. 
  • Select Properties
  • Go to the Compatibility tab. 
  • Check the box Run this program in compatibility mode for: and select an earlier version of Windows (e.g., Windows 10 or Windows 8). 
  • Click Apply and OK
  • Try opening the app again.

7. Disable antivirus or firewall temporarily

Why Disabling Antivirus or Firewall Helps: Sometimes, antivirus or firewall software can block apps from running. Temporarily disabling these can help identify if they are the cause. 

Steps to Disable Antivirus or Firewall

  • Open your antivirus or firewall software. 
  • Find the option to disable it temporarily. This is often found in the settings or system tray menu. 
  • Disable the software and try launching the app. 
  • If the app starts, consider adding it to the antivirus or firewall’s exceptions list. 
  • Remember to re-enable your antivirus or firewall after testing. 

Note: Disabling your firewall can expose your computer to potential cyber threats. Please proceed with caution and be aware of the associated risks. It is recommended to re-enable your firewall as soon as troubleshooting is complete to ensure your system remains protected. 

8. Uninstall and download the latest version

Why Uninstalling and Reinstalling Helps: Sometimes, the app installation might be corrupted or outdated. Uninstalling and reinstalling the latest version can resolve these issues. 

Steps to Uninstall and Reinstall

  • Open Settings by pressing Windows + I. 
  • Go to Apps > Installed apps
  • Find the app in the list and click on it. 
  • Select Uninstall and follow the prompts to remove the app.
