Error: Shared Parameter File Can Not Be Read/Not Valid

A shared parameter file from Revit 2022 and newer is not able to be used in previous versions.

Problem

Revit 2022 introduced new model categories. See Additional Model Categories. When a shared parameter file containing a reference to one of the new categories is accessed from a previous version of Revit, you will encounter an error saying the files can not be read or the shared parameter file is invalid. It is strongly recommended you save shared parameter files from previous versions before working with them in Revit 2022 and newer versions.

Solution

To use the shared parameter file in previous versions, you will need to remove references to the new categories from the shared parameters file.

Option A - Edit the file in Revit 2022

  1. Browse and open the shared parameter file in Revit.
  2. Locate and delete the parameter containing the new category.
  3. click Ok to save the change to the shared parameter *.txt file.
  4. Browse and open the shared parameter file in the previous version of Revit.

Option B - Edit the *.txt file directly

  1. Open the shared parameter *.txt file in a text editor.
  2. Locate lines in the file referencing the new categories. See list below.
  3. Delete the full line from the *.txt file.
  4. Save and close the *.txt file.
  5. Browse and open the shared parameter file in the previous version of Revit.
