New Installation Problem

Hello I have just upgraded to 2018 after a clean install. But after installing corona I got this problem everytime I open max. how can i solve this?
To solve it I have tried
Repair 3dsmax,
Clean install corona

UPDATE: I uninstalled everything and installed again. And now everything works fine, but this is not an actual solution..


DeadClown’s or my solution from this thread should help in similar cases: https://forum.corona-renderer.com/ corona converter flashes for a moment then dissapears #msg111575

Thank you very much, I have clean reinstalled everything then it solved. If happen again, I will try, thank you
