Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello Jeff Bryan,
I can see that you are having issue with Office 2019
Office Home & Student 2019 is a one-time purchase. Its support ended on October 14, 2025, but that alone should not stop a valid installation from creating or editing files.
Please open Word and check File > Account to confirm the product name, activation status, and signed-in account.
Then sign in to Microsoft account Services & subscriptions with the Microsoft account originally used to activate Office. If Office 2019 is listed, sign in to Office with that same account. You normally do not need the product key again after it has been redeemed.
If you have an unused 25-character product key, you can redeem it through Office setup. I would not rely on the registry to recover the complete key.
Since Office was preloaded by HP, also check your original receipt or order confirmation and contact HP if the licence is not listed in your Microsoft account.
If possible, please share the exact wording of the notice and the product and activation information shown under File > Account, with your email address and product key hidden.
Please note that Office 2019 has reached the end of its support lifecycle and is no longer supported by Microsoft on 14 October 2025. We recommend upgrading to a currently supported version of Office to continue receiving security updates and technical support.
Please feel free reply back to this post if you need further assistance, I'll be happy to help.
