See Microsoft Office Resources for information about getting software for personal and academic use, support, and training.

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.)
