I would like to inform you about installing AutoCAD Plant 3D 2022 Object Enabler above AutoCAD Plant 3D 2022.1.2. It will show as installed but will not be visible in the Windows > Control Panel > Programs and Features. Also, it will affect the AutoCAD Plant 3D objects to appear as wireframes in Navisworks Models.
Resolve this by installing AutoCAD Plant 3D 2022 Object Enabler before updating AutoCAD Plant 3D 2022. Later install all the updates.
