Ok. Well in that case you might need to resort to using some Variables and Advanced Actions.
You cannot selectively SHOW the Quiz Review button on the Quiz Results slide, and neither can you hide it underneath anything other than one of the default components of that slide (which is why I suggested using the Retake Quiz button).
You need to have a tracking variable that record whether or not the user Passed the quiz for starters. Have this variable set to 0 by default and set it to 1 On Slide Enter of the Quiz Results slide (using a conditional action) IF the learner passes the course.
If the user click the Review Quiz button, this will take the learner back to the first quiz question and also set a Captivate System Variable that tracks whether or not the user is in Review Mode. You can execute a conditional action via On Slide Enter of each quiz question to check whether the learner is in REview Mode and whether or not they Passed the quiz before allowing them to view the quiz question slide in Review Mode. If they haven't passed the quiz as yet, then the conditional action should jump them to a slide that tells them they need to pass the quiz before attempting to Review it.
Quite frankly though, I would rather give the learner 2 or 3 more attempts at the quiz (via a Retake Quiz button) before forcing them to redo all the content.
