IMPORTANT The process that installs Office 2016 also uninstalls all Office 2013 products. As you might expect, Word 2013, Excel 2013, and the rest of the Office suite are uninstalled. In addition, if a computer has InfoPath 2013, SharePoint Designer 2013, or certain versions of Visio 2013 or Project 2013 installed, installing Office 2016 also uninstalls those programs. You won’t be able to reinstall them.
1. Sign in to Office 365, at http://portal.office.com/ or https://login.microsoftonline.com/
If you don't see Office listed, your plan probably doesn't include Office applications. If you know your plan includes Office, you may not have a license assigned. If Office is not listed ask your Office 365 administrator to assign a license to you or for assistance.
2. On the Office page, select a Language, and then choose Install to install the 32-bit version.
NOTE To install the 64-bit version, choose 64-bit in the Version section before you choose Install.
4. Follow the prompts and accept the license agreement.
TIP After installing, you can start to use Word, Excel, and the other Office applications. These can be found by clicking the apps icon in the top left of Office 365 page.
