Unable to activate successfully downloaded MS Office 2024 on my MacBook Air running Golden Gate 27.0.1

I purchased Microsoft Office Home 2024 at an Apple store yesterday and today I successfully registered the software (I have an email from Microsoft confirming the purchase and registration). After registering the purchased software, I'm also able to successfully download the software onto my MacBook Air running Golden Gate 27.0.1. When I open any of the downloaded MS Office 2024 software applications, the opened software is recognized as Office 2021, which I had running on my Mac previously until it stopped running, which led me to purchase MS Office 2024. The exact message I get when opening any of the downloaded MS Office 2024 software applications is "Your Office 2021 is not supported with this version of the application." In the meantime, I followed the Microsoft installation and activation instructions multiple times and get the same result. Please help.

Please uninstall your Office apps. To uninstall, you move all Office apps, like Word, Excel, PowerPoint, Outlook, Teams to trash bin.

Then please use the instruction here: https://support.microsoft.com/office/how-to-remove-office-license-files-on-a-mac-b032c0f6-a431-4dad-83a9-6b727c03b193 Download and run the license removal tool to clear the cached 2021 license.

Then install this slightly older version 16.114: https://res.public.onecdn.static.microsoft/mro1cdnstorage/C1297A47-86C4-4C1F-97FA-950631F94777/MacAutoupdate/Microsoft_365_and_Office_16.114.26101123_BusinessPro_Installer.pkg?atp=ets

See if it works.

    This usually means the Mac is still using old Office license data from the previous Office 2021 installation.

    Try this in order:

    1. Remove the old Office license files on the Mac.
      • This is the recommended first step when a newer Office for Mac purchase keeps showing an older license.
      • After the license data is removed, reopen an Office app and sign in again with the Microsoft account that was used to register Office Home 2024.
    2. If the apps still behave like the old installation, remove and reinstall the Office apps.
      • Close Word, Excel, PowerPoint, and Outlook.
      • In Finder > Applications, locate the Office apps and move them to Trash.
      • Reinstall using the Microsoft installer package for Mac.
      • When installation finishes, open Word from Launchpad, select Get Started, then Sign in and enter the email address associated with the Office purchase.
    3. If activation still fails, use the Mac activation troubleshooting steps or contact Microsoft Support.

    Notes relevant to this case:

    • Office 2024 for Mac needs internet access for the initial install and activation.
    • A similar supported resolution for this exact symptom on Mac is to remove the old Office license, then sign back in to activate the new Office 2024 purchase.
