I just downloaded the installers for the plugins I have which were just updated to native support for Apple Silicone, but the first 2 I tried couldn’t upgrade the installations I already have (I’ve tried Archetype:Rabea and Imperial Tone King MKII).
Have you been able to resolve this? I tried updating Gojira, Rabea, Nolly, and Petrucci, but I keep getting the same “The Installation Failed” message that you reported. Hopefully this is getting looked at and we get an answer.
I have the same issue currently on Ventura, have spoken to support but they have just said it’s a permissions issue. However all of my permissions are correct. Would be good to know if/how you solved it?
