The Microsoft Home Use Program (HUP) for Microsoft Office has been changed recently. They no longer offer the full download of Microsoft Office. If you have already purchased Office 2016 or 2019, you should be fine.
As an alternative, they are offering discounted access to Office365. I have been unable to connect to the licensing center to configure this today, but I will send an email with details when I have them. It looks like it is going to be 30% off the $99 annual subscription. Alas, not as sweet a deal.
