Okay, I'm stuck.
I have downloaded everything on my computer, editor, latest driver, updater.
But there was no installation guide.
And without connecting to the Helix you can't use the updater, because in both online and offline mode it just shows a screen, where you must (but can't) select a device ...
So obviously the line "None of this requires the Helix device to be connected." does not seem correct anymore. Or did I make some mistake somewhere?
