Hi @Barbara Graham
If “Office Professional 2018” dos not appear under Settings → Apps → Installed apps or Control Panel → Programs and Features, then it may no longer be installed as a separate Office suite.
What you are seeing under Change or Update License may simply be an older Office license associated with the Microsoft account or leftover licensing information on the computer.
I would first check:
Control Panel → Programs → Programs and Features
Search for anything named Microsoft Office, Microsoft 365, Office Professional, Office 2019, Office 2021, etc.
If no older Office installation appears there, I would not try to delete files manually.
Instead, use Microsoft’s official Office uninstall troubleshooter to remove any remaining Office 2016/2019-era installation components and licensing remnants. Microsoft specifically provides this tool for cases where Office cannot be cleanly removed through Windows.
After the cleanup:
Restart the computer.
Sign in to the Microsoft account that owns Office Home 2024.
Install Office Home 2024 from the Services & subscriptions section of that Microsoft account.
Open Word or Excel and sign in with the same account to activate it.
One important note: the uninstall troubleshooter can remove older Office versions, but Microsoft currently states that it cannot uninstall Office 2024 itself. That is fine in your case if the goal is only to clean up the previous Office installation.
Also, do not remove the old product from your Microsoft account just because it appears under licensing. An account can legitimately contain more than one Office license.
If Office Home 2024 is already installed but keeps selecting the older license, let us know what appears under:
Word → File → Account → Product Information
and we can troubleshoot the activation state directly.
