Can anyone confirm whether or not the Houdini Launcher and Houdini are supposed to be working on Sequoia 15?

They work for me on my M2 Air. I will say though that when I first tried it the Launcher would just crash immediately. I re-installed it and it seemed to be okay afterwards and I was able to launch Houdini successfully.

You’re right! I forgot if Launcher crashes to reinstall it.

Okay, I’ll try again when I get home.

Thanks.

When I install Houdini Launcher on Sequoia it works fine until I update it. Further, I was able to install Houdini with the launcher with Launcher V 20.0.506 M1. Once I go to install HQueue 20.5.332 it states I need to update the Launcher. Once Launcher updates, it fails again...

Yup. I force deleted Launcher and did not update it on the 2nd install.

Running fine since.
