Which versions of Autodesk Revit are supported?
KitchDesigner is available for Revit 2017, Revit 2018, Revit 2019, and Revit 2020.
If you already had KitchDesigner installed and you recently downloaded a newer version of Autodesk Revit, you will need to uninstall KitchDesigner and then reinstall KitchDesigner to add support for all supported versions of Autodesk Revit.
