They were made by Spectral Design, not Steinberg.
This thread was made because the thread starter assumed that the removal of 32 bit support was causing issues with his plugins. But they’re clearly 64 bit, otherwise they wouldn’t even show up, so that’s definitely NOT the source of his issues.
I’ll lock this thread because it’s clear that people will continue to rant about off-topic issues while completely ignoring the thread starter. I’ve asked him to contact Steinberg Support, which should be able to help him figure out why Halion is freezing.
