Hi,
How did you install Office 2021?
Did you use ODT to deploy Office 2021?
If you're using ODT to deploy Office 2021, you can only install the Office 2021 Product ID without Visio and Project Product IDs.
Please refer to this support article: https://learn.microsoft.com/en-us/deployoffice/ltsc2021/deploy
If you're using other ways to install, please provide more information here. Please let us know if you would like further assistance.
