I installed it without error, when I start the program a screen flashes and goes away, too quick to be able to read what it says. I see people posting log files, where can I find that file? And has anyone else ran into this problem?

Hi. Please try newest beta v14.5. It is pretty stable now, and it should start without issues.

Please install the V14.5 beta as suggested. Any changes for Ubuntu 18.06 will be made to this version, since V14 is approaching the end of its release life.
