Step-by-step installation instructions

The drop-down below contains steps to install Office on your PC (laptop, desktop, or 2-in-1), or a Mac. These steps also include instructions for how to install Office in a different language and how to install the 64-bit version of Office.

The steps to install Office are different depending on whether your Office product is part of an Office for home or Office for business plan.


  • Sign in with your work or school account at

    Note: If you’re unable to sign in you may be signing in to the wrong Office 365 service, see Where to sign in to Office 365.

    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, see What Office 365 product or license do I have? If Office is not listed ask your Office 365 administrator to assign a license to you.

  • On the Office page, go to the version of Office you want to install. For example, your admin may have given you the option to install either Office 2016 or Office 2013.

    If you have a choice, select which version of Office you want to install, select a language, and then select Install.

    Important: The process that installs Office 2016 also uninstalls all Office 2013 products. See “Stop, you should wait to install Office 2016” error or How do I reinstall Office 2013 after an Office 2016 upgrade.

  • Select a Language, and accept the default to install 32-bit, or select Advanced and choose 64-bit from the drop-down list. If you’re not sure which version to install, see Choose the 64-bit or 32-bit version of Office 2016.

    Important: If you currently have the 32-bit version of Office (or a single, stand-alone Office app such as Visio) installed on your PC, you’ll need to uninstall that version before you can proceed with installing the 64-bit version.
