What happens if you can no longer find the product key as it’s been a number of years since installation ☹️

The answer was in my initial post.

A 5+ hrs. slog with the massive help of AI.

The AI understood how MS applies update, Office 365 and the telltale signs of what happened and my prompts.

Also, I had the original software downloads and product key. But do not be fooled, this was NOT a case of simply deleting reinstalling software.

Did you successfully install Office? Does your Microsoft account subscription include Office?

No you can't, not when office 365 hijacks your system.

When you first activated Office 2019 that licence should have become associated to your Microsoft Account as a digital licence online, the product key can no longer be used and it is from there that you can re-install Office without the need for a product key:

My version of Office Home and Office 2019 was preinstalled on a Dell laptop, along with Win11. I used Office yesterday, and it's gone now; probably related to KB5002907.

There is no COA for the OEM licenses. What do I do?

I feel your pain Brother.

It took me, Gemini, over 5 hrs, non stop, to work thru the issue (no way to contact Microsoft for help). I was fortunate because I had the original software downloads and the product key.

Gist of it seemed to be that after the update, Office 365 took control and would not let the standalone Office 2019 come thru.

Obviously, I'm not at IT person but wow, frustrating for sure.

Good luck

I've lost my access to 2019, MS365 wants me to subscribe but need 2019 not 365!!

My account is saying MS365 was cancelled in 2023, I've never had it, and Office 2019 now not listed?

HELP
