More information

For Windows users

  • Office 365 Pro Plus is not compatible with the Windows installer versions of Visio and Project that are available from Essential Stanford Software. See Office installed using Click-to-Run and Windows Installer on same computer isn't supported for more information. (Click-to-run is the technology used to install Office 365 Pro Plus; Windows Installer  technology (MSI) is the technology used to install Visio and Project .)
  • Make sure all versions of Office, Visio, and Project  are either 32-bit or 64-bit. You can’t have a mix of both. (Essential Stanford Software distributes the 32-bit version of all.)
