Ah yeah, I had the same issue with the demo … I had to get @CarlMikaelBjork to kindly send me the application buried within the installer … it all fell down for me when trying to install via the installer rather than installing the main executable - maybe see if someone can extract the executable on a Windows machine or pinch one from someone who has succeeded
I don’t think installing via the installer is insurmountable, it was just too much hassle on my attempt so I cut that step out
