Begin by opening Software Center, either by clicking its icon in the Start menu or by searching for "Software Center" in the search bar in the task bar.
Next, find "Microsoft 365 Apps for Enterprise" in the list and click on it.
Finally, click Install. The install will begin and should automatically replace your current version of Office. If you receive an error or experience issues with the installation, please submit a helpdesk ticket.
IMPORTANT: After the installation is complete, you will be prompted to sign in to Office when you launch any of the apps (Word, Excel, Outlook, etc.). You will need to enter your NetID as [email protected]. This will license the products and you should be all set.
