Before you run the installer:
Make sure you uninstall any versions of Office you have on your computer.
This includes trial versions, and versions with an expired license.
Note for Chromebook/Cloudbook/HP Stream users:
These devices cannot install the Office suite due to hardware or software limitations. The Microsoft site does have web versions of the Office apps available, accessible from icons on the left side of the page. These web apps may not have the exact same feature set as the full programs.
