3. Select Install Office. After the installation file is downloaded, what happens next depends on which web browser you use. When you select Install, a dialog window at the bottom prompts you to either run the file, save it, or cancel. Select Run and work through the installation process.
4. If the User Account Control asks whether you want to allow the app to make changes to your device, select Yes.
5. Once you run the downloaded file, the installation process begins automatically. If Windows asks if you want to allow the installation, select Yes. If it prompts you to close any open programs, select Yes again.
6. The 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.
7. Microsoft Office is now installed and ready to use.
