Long time since I last used H5 in Ableton

I need you to updated me :blush: Is the AU version 32 bit only?
Ableton 64 bit is crashing when loading Halion 5.

It turns out that the only Steinberg plug-ins thatโ€™s working both 32 and 64 bit in Ableton is Padshop and Retrologu.

The following plug-ins are crashing the 64 bit version of Ableton Live when dragged into the project: Halion 5, Groove Agent, Halion Sonic 2, Triebwerk, Hypnotic Dance and Dark Planet.

Any idea where I should start troubleshooting?
