Step 1 - Sign in to download Office

Step 2 - Install Office

Depending on your browser, click Run (in Edge or Internet Explorer), Setup (in Chrome), or Save File (in Firefox).
If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device? Click Yes.
