Some new information : I seem to have the same problem in Komplete Kontrol.
When scanning for plugins, it gives the same error message as Ableton ‘Spectralayers ARA. Spectralayers path could not be found’ and Spectralayers is also in Komplete Kontrol’s plugin list.
When scanning with FindAnyFile, no sign of anything from Steinberg or Spectralayers, even in hidden files so nothing to delete…
Really weird.
