For example, the volume licensed version of Office Professional Plus 2019 can only use the PerpetualVL2019 update channel. For Office 365 and Office 2019 products, all products installed on the computer must be using the same update channel.The same is true for volume licensed versions of Project and Visio. Volume licensed versions of Office 2019 use Click-to-Run. Volume licensed versions of Office 2013 and Office 2016 use Windows Installer (MSI).For example, we don’t recommend having two different versions of Office installed on the same computer, such as Office 2013 (MSI) and Office 2019 (Click-to-Run). Even though a particular installation scenario is supported, it might not be recommended.For example, you can’t install a 32-bit version of Visio on the same computer with a 64-bit version of Office. All installed products must be either the 32-bit version or the 64-bit version.See the example installation scenarios section for several examples of installation scenarios that are supported and not supported, along with an explanation of why they are or aren’t supported, based on the rules listed above. You can’t install two products of different versions together if both products use Click-to-Run as the installation technology and those products have overlapping Office applications.You can’t install two products together that have the same version but use different installation technologies.What governs whether an installation scenario is supported are these two rules: The two main things that determine whether Office, Project, and Visio can be installed together on the same computer are the version of the product and the installation technology used to install the product.

But, there are some combinations of Office, Project, and Visio that can't be installed together on the same computer. In many cases, you can install Office, Project, and Visio on the same computer.
