Can't load any Halion instrument sets

Hey all - I have a new install of Cubase Artist 10 on Windows 10.

I’m trying to load up the Trip and Flux instrument libraries that are supposed to come pre-installed. But I get a kind of buggy UI that does this:

I’ve tried uninstalling and reinstalling both Cubase and the Halion component. At the suggestion of support, I also tried running the Microsoft .NET framework repair tool. Nothing has worked so far.

Does anyone have idea ideas about what else might get this thing working, or am I in an unwinnable battle against a software bug?
