And ran slmgr /rearm in a command prompt. This allowed me to run the "Change product key" option and it said it finished successfully. However, when I run license check programs like Nirsoft's ProduKey it is still showing the other Product ID and Product Key for both Internet Explorer and Windows 7 Professional.

In reply to RonBarker's post on October 30, 2023. Hi, you do not need the Product Key once Office 2019 has been installed. You do need to be able to sign in with the 'registered account'. If your Office is working open an App, e.g. Word>File>Account>top left hand side you should see the email address for the 'registered account'.
