After installing Navisworks 2023, uninstalling Autodesk Revit Engine 2023 will prevent Revit files from loading in to Navisworks. As there is no longer a repair option in the Navisworks installer, a full reinstall of Navisworks 2023 is required to fix this issue (NW-57695).
During installation of Navisworks 2023, you may see a dialog box informing you that a reboot is required to complete the setup. If you click OK on this dialog box, the installation should complete as normal and prompt you to reboot at the end. If you click Cancel or close the dialog box, an error message is displayed and you will have to restart the installation (NW-57658).
Inventor Switchback functionality is not currently working in Navisworks 2023 (NW-57682).
This has now been resolved.
