Update: I was able to solve this using the suggestion in the linked thread below to download the installer on a Windows computer and copy over to a Mac. Then the installer worked like a charm.
I had the same crash (under macOS Mojave 10.14.3), and trying to run the installer from within the package contents *appeared* to work but only installed the /Applications/Hauptwerk items, it didn't make any of the necessary folders at the root level of my HD. I'm copying over folders from my backup install, but is there a trick to making the installer work? I'm trying for a super clean, brand new Hauptwerk install...
I already installed the Sentinel HASP drivers from downloadhauptwerk.com and ran the Java 6 installer as well, so that's not it.
I found
this thread from 2016 documenting some installer issues and possible solutions — is that still what is happening now? I will try some of the suggestions in that thread tomorrow.
Thanks,
Jeff
