Revit Issue: "The default family template files are invalid"

July 10, 2024 Gregory Lee

Application Version: Applied All Revit

The warning persists when starting Revit, even after updating the family template folder path.


There are two possible causes for this issue:

  • The Revit.ini file is not updating due to a system issue.
  • The Revit.ini file is being overwritten due to Group Policy.

To resolve the issue, updating the Revit.ini files is necessary. There are two separate locations for the Revit.ini file:

  • The main Revit.ini file that dictates Revit settings is located at:
    • C:\Users\<username>\AppData\Roaming\Autodesk\Revit\<product name and release>
  •  The Revit.ini file used the first time Revit is open is located at:
    • C:\ProgramData\Autodesk\<product and release>\UserDataCache


  1. Open both Revit.ini files mentioned above.
  2.  Add the following lines after the [Directories] section:
    • [DirectoriesDEU]
    • FamilyTemplatePath=C:\ProgramData\Autodesk\RVT 2022\Family Templates\German\
    • DataLibraryLocations=Metric Library=C:\ProgramData\Autodesk\RVT 2022\Libraries\German\
    • DefaultTemplate=BIM Architektur und Ingenieurbau (vereinfacht)=C:\ProgramData\Autodesk\RVT 2022\Templates\German\BIM_Architektur_und_Ingenieurbau-Vereinfacht.rte, BIM Architektur und Ingenieurbau=C:\ProgramData\Autodesk\RVT 2022\Templates\German\BIM_Architektur_und_Ingenieurbau.rte, BIM Gebäudetechnik=C:\ProgramData\Autodesk\RVT 2022\Templates\German\BIM_Gebaudetechnik.rte
  3. Save the changes to both files.
  4.  Reboot your computer after updating the Revit.ini files.
