Miscellaneous topics that do not fit into specific categories.
In your account, there is a separate category for installing (and downloading) your Office products. Go to https://account.microsoft.com/services . Subscriptions are shown at the top, and one-time payment licenses at the bottom. Click the Install button next to your product.
Note that if you ordered online, you may have received a product key that you need to redeem at https://setup.office.com first. The redemption key can only be used once; after it has been associated with an account, you access the account to manage your product.
