Hi, I'm John! I will help you with this.

Before installing, it’s a good idea to uninstall all existing versions of Office to avoid conflicts.

Here’s how:

  • Open the Control Panel > Programs > Programs and Features.
  • Look for any version of Microsoft Office or Office apps, right-click, then choose Uninstall. Please uninstall all Office apps.
  • Once that’s done, restart your computer just to be safe.

Then, to reinstall Microsoft Office:

  • Go to https://account.microsoft.com/services
  • Sign in using the same Microsoft account linked to your subscription.
  • Find your Microsoft Office 2021 Home & Student and click the "Install" button.
  • That will download the installer for the Office apps, just run it and follow the steps.

If anything’s unclear or the "Install" button still doesn’t show, feel free to let me know. I’ll be happy to walk you through it!

I really hope this information is helpful! Let me know if you have any further questions or concerns.

Regards,

John J.D.
