    To address the issue with Office code 400-4 and to reopen your support case, you can follow these steps:

    1. Contact Microsoft Support: Since your previous case was closed, you will need to submit a new support incident. You can do this through the Microsoft support website or by calling their support line. Make sure to have your case number handy, as it may help them reference your previous interactions.
    2. Provide Details: When you contact support, explain the issue you are experiencing with the Office installation and mention that the previous case was closed without resolution. This will help them understand your situation better.
    3. Follow Up: If you encounter the same issue after following their guidance, you may need to submit a new support incident, especially if the error occurs on a different machine or document.
    4. Repair Office: As a preliminary step, you might also consider performing a repair on your Office installation. You can do this by going to Settings > Apps, selecting Microsoft Office, and choosing the Repair option.

    These steps should help you get back on track with resolving your Office installation issue.

    Do you have the installation media and the product code? You will need both of those to be able to install that version, which is NO LONGER SUPPORTED BY MICROSOFT.

    I am surprised that the Tech Support did not advise you of that fact.
