SOLVED No Wavelab installation found - after reverting to 12 Pro from the Pro 13 Trial - macOS Tahoe

I recently uninstalled Wavelab 13 Pro Trial and reverted back to using my licensed Pro 12. However, both in Cubase Pro 15 and Nuendo 14 (also Reaper) when trying to use Wavelab as an ARA extension I’m getting a “No Wavelab installation found - please reinstall Wavelab” message.

I’ve uninstalled / reinstalled it to no avail. It works fine in standalone mode.

Any suggestions?

EDIT: I’ve re-installed Wavelab Pro 13 Trial (expired), and now when I choose Wavelab ARA from Cubase / Nuendo, it pulls up WaveLab GO in the lower pane. Wavelab 12 Pro (licensed) is still installed.

SOLVED: WaveLab 13 VST3 was not deleted from the VST3 folder when uninstalling it. I manually deleted it, then reinstalled Wavelab 12 Pro. The installation placed the correct VST3 file in the folder.
