How do I allow parental controlled users to access third party apps on the admin account?

I just set my son up with a separate parental controlled user account and he can't seem to access some third party games that we installed for him under my admin account. He has saved progress on these games that we don't want to lose, so I don't want to reinstall them. I checked them off as allowed apps, but when he tries to play- the game icon shows up in the doc then changes to the updater icon and they won't run. I've searched for answers to this question, but can't seem to find any. Please help? My son and I would be very grateful!
