Can’t switch from Office 365 to Office

If you try to install Office 2019, Office 2016, or Office 2013 and you get an “invalid product key” message, the problem might be that you already have Office 365 or an Office 365 Trial installed. Before you can install Office, you’ll need to remove Office 365.

Uninstall Office 365 and install Office

  1. Click the button below to download and install the Office uninstall support tool. (This tool won't uninstall stand-alone apps such as Project or Visio. For stand-alone apps, uninstall the app using the control panel.)
