Hi all! The issue happens because the installation of Cinerender folder remained incomplete while running the 4020 update.
It is caused by a stucked MAXON related process in the task manager, called ‘qtguiagent.exe’. (This process starts with the Cinerender64.exe but in some cases it might get stuck in the task manager even after closing ArchiCAD. When installing Update 4020, this stucked process prevents the installer from updating the CineRender folder properly.)
There are two workarounds:
1.
- run the 3006 installer repair on ArchiCAD 18
- go to the task manager and make sure that the process qtguiagent.exe is not stuck, if it is stuck, end the process
- run the 4020 update
2.
copy the full cinerender folder from another computer where the update ran through without a problem or was not yet installed
