How to Fix NotificationController.dll Missing Error on Windows

  1. Restart your computer: Sometimes, a simple restart can fix temporary glitches and resolve missing DLL errors. Restart your computer and check if the error persists.

  2. Check the Recycle Bin: If you recently deleted any files or programs, including the NotificationController.dll file, it's possible that it was accidentally moved to the Recycle Bin. Open the Recycle Bin, locate the file, right-click on it, and choose "Restore" to return it to its original location.

  3. Run a malware scan: Malware infections can cause DLL files to go missing or become corrupted. Perform a full system scan using a reputable antivirus or anti-malware software to detect and remove any potential malware. Ensure that your antivirus software is up to date before running the scan.

  4. Use System File Checker (SFC) tool: The System File Checker is a built-in Windows tool that scans and repairs corrupted system files, including DLL files.

    • Open the Command Prompt as an administrator: Press the Windows key, type "cmd," right-click on "Command Prompt," and select "Run as administrator."

    • In the Command Prompt window, type the following command and press Enter:

      sfc /scannow
    • The tool will scan your system for corrupted files and attempt to repair them. Be patient, as the process may take some time to complete.

    • Once the scan is finished, restart your computer and check if the error is resolved.

  5. Perform a system restore: If the error started occurring after installing a new program or making changes to your system, performing a system restore can help revert your computer back to a previous state before the error occurred.

    • Press the Windows key, type "restore," and select "Create a restore point."
    • In the System Properties window, click on the "System Restore" button.
    • Follow the on-screen instructions to choose a restore point and initiate the restoration process.
    • After the system restore is complete, your computer will restart. Check if the error has been resolved.
  6. Reinstall the application: If the missing DLL error is specific to a particular program, try reinstalling the application. Uninstall the program from your computer, download the latest version from the official website or a trusted source and reinstall it.

  7. Update Windows: Keeping your Windows operating system up to date ensures that you have the latest bug fixes and patches. Check for any pending updates by going to Settings > Update & Security > Windows Update and clicking on "Check for updates." Install any available updates and restart your computer.
