Activating Office 2019 Professional Plus on Windows 11: Invalid Product Key Error

Question

Hello,

I am facing an issue activating Office Professional Plus 2019 on my newly purchased work PC that was updated to Windows 11 Pro. The error message indicates "Invalid Product Key Code." However, the same product key is working on two other Windows 10 machines. I followed the process of accessing the website https://setup.office.com to download the product. Has anyone experienced the same issue and knows how to resolve it?

Thank you.
