Twinmotion Not Detected by Revit 2025 After Updating to 2025.1.1

I’m encountering an issue where Revit 2025 is unable to detect Twinmotion 2025.1.1 and 2025.2, despite having the correct version of Twinmotion installed. The error message I receive is: “A supported version of Twinmotion is not installed.”

Details:

  • Revit version: 2025 (fully updated to version 2025.1.1)

  • Twinmotion version: 2025.1.1 and 2025.2

  • Problem: Revit no longer recognizes the installed Twinmotion version, and the “Open in Twinmotion” option is unavailable.

Additional Information:

  • This issue started after updating to Revit 2025.1.1. Twinmotion was working fine previously (prior to the update).

  • Actions taken:

    • I have reinstalled both Revit and Twinmotion multiple times and made sure both are up-to-date.

    • All necessary Windows updates have been applied.

    • I’ve ensured the Twinmotion plugin is not required for Revit 2025. However, even without the plugin, Revit still fails to detect Twinmotion.

    • I checked the Revit Add-ins folder, and the plugin isn’t showing up.

What’s happening:

Despite all efforts, the Twinmotion integration for Revit stopped working after the update to Revit 2025.1.1. It was working fine before, and now Revit cannot detect Twinmotion.
