I'm at my wits end. Autodesk Flame 2020 for High Sierra is installed, thanks for the information given, however, it will NOT open. It tries to open but immediately closes. It never asked us for the serial number, so I'm guessing that it didn't install correctly. We did notice that the installer didn't create the discreet folder.
We've lost so much time and money over Autodesk over the years and I wonder if it's worth continuing to use the products?
We even tried to download the trial version, after issuing all of the above terminal commands and GOT THE EXACT SAME THING. Someone please help fix this situation.
