Me too. Impossible to get started if you can’t even get the program to launch. 
What operating system are you trying to run Personal Historian on?
Currently, Personal Historian runs on macOS Mountain Lion (10.8) through macOS Mojave (10.14) and Windows 7 SP1, 8, 10, or 11.
Are there plans to update so does run on later MacOS machines as well just like RootsMagic 8 ??
Yes, but I couldn’t speak to if that would an update or upgrade.
