I didn’t mean to offend you. I was just asking if you where guessing or if you had been in the same situation. I’m well aware that programs in windows are removed by the “add remove programs” feature, but HALion6 in my case didn’t work properly when doing so. Wasn’t aware there’s something called the Halion Library Manager, perhaps I should have tried that one, might have helped me.
… But now I’ve reinstalled Cubase9.5 from scratch removing all data files and settings I could find. I’m back on track again.
