This doc lists potential compatibility issues with Microsoft Office, Visio, and Project as they pertain to the centrally-distributed Windows software at UW-Madison.

If the Update option is missing or you're unable to update, try Microsoft Update to install your Office updates through Windows. To download an update manually, see Office Updates. If you would like to update Office but can't open any of your Office apps, try repairing your Office suite: Go to Control Panel Programs Uninstall a program. Tech support scams are an industry-wide issue where scammers trick you into paying for unnecessary technical support services.

On one machine:

You cannot mix bitness. Office, Visio, and Project must all be either 32- or 64-bit.
You cannot mix Office software installed with different types of installers. All must be Click to Run or all must be Windows (MSI) Installer.
- These use only the Click to Run Installer:
  - Office 365, Office 2019, Visio 2019, and Project 2019.
  - Office 2013 and 2016 installed from the Office 365 portal.
- These use only the Windows (MSI) Installer:
  - Visio and Project versions 2013 and earlier.
  - Office 2013 and 2016 downloaded as ISOs from the Campus Software Library.
- These use either Click to Run or Windows (MSI) installers:
  - Visio 2016 and Project 2016
You cannot mix different year versions (2013, 2016, 2019, etc.). Office, Visio, and Project must all be the same year version, with the exception for Office 365 noted below.
- Any Microsoft software installed with a Click to Run installer can be installed alongside Office 365. That would include Visio 2019 or later, Project 2019 or later, and the Click to Run versions of Visio 2016 and Project 2016. If you have both Project and Visio installed, their versions must be the same as each other.
