If your computer came with Office 365 pre-installed, or if you have Office 365 installed from a previous subscription, please un-install it from your system first otherwise it overrides the following installation and says you subscription has expired (this is a bug Microsoft has never fixed).
Run the setup file downloaded to your computer to install the Office applications.

Your install is finished when you see the phrase, “You’re all set! Office is installed now” and an animation plays to show you where to find Office applications on your computer. Select Close.
Follow the instructions in the window to find your Office apps. For example depending on your version of Windows, select Start and then scroll to find the app you want to open such as Excel or Word, or type the name of the app in the search box.
