Install button and the check boxes are not active, only the Cancel button is active. I assume because the Bandlab assistant somehow thinks they were installed already, but the Apps & Features page in Windows settings does not show the studio instruments like the Bandlab Assistant says it will. Melodyne is present as an app in Windows but the rest is absent (Drum Replacer, Theme Editor and Studio Intruments Suite are nowehere to be found, neither inside Cakewalk nor outside)
