However, if this is the first time you’re installing Office, you may have some pre-installation steps to do first.

  2. 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.Follow the instructions in the window, for example Click Start > All Apps to see where your apps are, and select Close.

Step 3: Activate Office
