I purchased Office Home & Student 2019 and have been using it until today. The unsupported version of Word specifically stopped working, but when I redownload the last version of Office that this license works with (16.78.3), I still can't use Word.

These is the message I get: "Activate Microsoft 365 to create and edit". I've double-checked that the version is correct, but can see the message "License: not activated". I don't know how to reactivate the license I've already purchased. When I go to my Microsoft account, I find no mention of the license, but I can see it in my purchase history.

I have a MacOS if that's useful to know.

How can I get this older version working again with the lifetime license I purchasedScreenshot 2026-11-10 at 10.04.31 AM

    You may be able to find an Activate command in the Word menu in the main menu bar. Even if you can activate, though, the product has been retired which renders it unusable for editing, creating or saving.

    I'm sorry to be the bearer of bad news, but Office 2019 can't be used on a Mac anymore. You won't be able to activate that version on your Mac.
