Just registered & installed Halion Sonic SE3 on my Win10 laptop. Used these two files:
Got one Shortcut icon for Halion Sonic SE, another for Steinberg Library manager (with Factory Content, Artist, & Factory sections) and another for eLicensor control (input my serial # no problem)
Halion Sonic SE Fires up just fine. Drag a bass sound up into track 1, and get a popup that looks like this one from a 2018 thread about this same problem:
“Some audio files are missing – Please check installation”
The previous thread about this mentioned reinstalling from .msi files, but that’s not what I’ve got. These are .exe’s.
Otherwise, after dismissing the error popup, and poking at the virtual keyboard along the bottom with my mouse, the midi yellow lights are lighting up, but no sound.
