Application failed to start because no Qt platform plugin could be initialized

When opening the eazyBackup application, you might see an error message similar to:

This application failed to start because no Qt platform plugin could be initialized.

This error typically occurs when the Qt platform plugin, which is required for the application to run, is missing or corrupted. The Qt platform plugin is bundled with eazyBackup, it is not a component of the Operating System. The Qt plugin provides access to the applications underlying graphical user interface (GUI) functionality, such as rendering windows, buttons, and other graphical elements.

  1. In most cases, the error will be caused by a corrupted installation of the eazyBackup software. Try uninstalling and reinstalling the application. Download the latest version of the application here:

  2. Errors related to the Qt platform plugin could be caused by file system corruption. If you are receiving errors related to the Qt platform plugin, it would be a good idea to check and repair any damaged System Files:

    1. Type cmd in the search box, and then right-click Command Prompt and select 'Run as administrator'.

    2. Type the following command in the elevated command prompt and hit Enter:

      sfc /scannow

      The SFC tool will scan and try to repair the corrupted system files automatically.

  3. If the SFC failed to repair any corrupt system files, you can also run the following DISM commands from the elevated command prompt:

    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth

The "/Online" parameter specifies that the command will be applied to the currently running operating system, as opposed to a mounted offline image.

The "/Cleanup-Image" parameter specifies that the command will perform a cleanup of the system image. This cleanup can remove files that are no longer needed, reduce the size of the component store, and make it easier to maintain the system.

The "/CheckHealth" parameter instructs DISM to check the health of the system image and report any issues it finds. This can be useful for diagnosing problems with the operating system or identifying corrupt or missing files.

The "/ScanHealth" parameter instructs DISM to scan the system image for component store corruption and other issues, but without repairing them. The scan only reports the issues found, without attempting to fix them.

The "/RestoreHealth" parameter instructs DISM to repair the system image by restoring any missing or corrupted files from a known good source. This may require an internet connection to download replacement files.
