When you start Revit after installing a Naviate 2023.1.7 product you are getting this error message.
This message says that the file help32.png is missing under C:\Program Files\Symetri\Naviate\Revit 2023\Images
To solve this uninstall all Naviate 2023 applications (including AC and HE) and then install the application again, eg Naviate A, (then the latest version of AC and HE will be installed automatically).
