  1. After checking literally every security setting for IE the solution is as easy as effective. Thank you so much.

  2. Mate, thank you so much. As we know hybrid mode makes the migration so much easier. I was starting to think I would need to use a third party to do the migration until I saw instructions. Thanks again.

  3. I tried this and it will not work either.
    Keep getting “Cannot download the application. The application is missing the required files”

    1. I followed the steps on a new Windows Server 2016/2019/2022. The application started after entering the HybridWizard URL in Internet Explorer.

      Use the browser Internet Explorer. If it’s another browser, ensure that you enable ClickOnce support.

  4. No longer works. This functionality was moved to Settings app and now IE is not an option for .application.
    New method:
    1. Create text file on computer.
    2. Change extension to .application.
    3. Open properties.
    4. Change Opens with (IE is now an option).
    Microsoft insists on breaking the good old Control Panel applets with providing a proper replacement. Welcome to OS as a “service”.
