Problem:
I follow the guidelines in Download and install or reinstall Office 2019, Office 2016, or Office 2013 which state that I should :
From the top of the page, select Services and subscriptions
I don’t have anything at the top (checked 3 browsers).
I have a license for office 2019 and I would like to use it on my Windows 11.
Resolution:
Microsoft 365 is offered on a subscription basis. You pay a regular fee (usually monthly or annually) to use the software. This subscription includes access to a range of services beyond just the Office applications.
Whereas Office 2019 is a one-time purchase. You buy the software license outright, and you can use the included applications as long as you want.
Thus if you have a license, You can install Office 2019 on Windows 11.
