    When double clicking on a Revit project or family file within Windows explorer, the wrong version of Revit opens the document. Is it possible to specify which version of Revit accesses the file?


    Yes it is, although this process is not generally recommended when working within a Revit Workshared environment, because Windows does not understand Worksharing and can result in file access permission issues if performed on a live project.

    If this is a likely risk, then the user must access a file from the Revit software where a local copy will be created. If this is not the case, then it is possible to change the configuration with the Registry Editor.


    This task should be performed by a competent user, familiar with the Regedit function who understands the importance of backing up the registry before any changes are made.

    Backing Up System Registry

    • Run Regedit
    • Locate the following key:
    • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Revit.Project\shell\open\command
    • Double click on (Default)
    • Change the Value Data to the desired path within the quotes (do not change the /dde part of the Value Data). i.e., Replace the Value with C:\Program Files\Autodesk\Revit XXXX\Revit.exe /dde (Replace XXXX with the suitable version number e.g., 2020)
    • Click OK and close the registry dialog box.

    Now when double clicking a Revit file the appropriate version of software will run.
