To begin, download the most current version of the Office Deployment Tool from the Microsoft Download Center. For more information about deploying volume licensed versions of Project 2021 and Visio LTSC 2021, see Deploy Office LTSC 2021.

You need a different MAK key to deploy volume licensed versions of Project and Visio with the Office Deployment Tool. MAK keys that you use for Windows Installer (MSI) installations of Project and Visio won't work with the Office Deployment Tool.
