Hi,
How did you activate Office Professional Plus 2019 before?
Where did you buy the Office Professional Plus 2019?
Is it a sudden prompt that needs to be activated after the recent update?
Have you ever tried re-entering the key directly to activate?
This might involve running Office as an administrator, ensuring your system date and time are correct, or checking your internet connection.
If all the settings are correct, you might need to uninstall and then reinstall Office. Use the Office Uninstall Support Tool to completely remove Office from your PC before reinstalling.
Please be a bit more precise to explain your problem so that I can get more accurate solutions to this problem. I’m glad to help and follow up your reply.
