Download and install or reinstall Office 365 or Office 2019 on a PC or Mac

Office for home    Some Office for home products come with a product key. If yours did, before installing Office for the first time, sign in with an existing or new Microsoft account and enter your product key* at office.com/setup. Redeeming your key is what links your account with Office so you only have to do this once. Already did this? Go to Step 1.

Office for business    If your Office for businesssubscription plan includes the desktop version of the Office apps you won’t see an option to install it unless someone in your organization assigned a license to you. Learn how to check this in What Office 365 business product or license do I have? or if you’re an Office 365 admin, see Assign licenses to users.
