I could not complete my purchase/installation of cleaner one pro because I could not find any where to write the activation code. What do I do?
Hi，Thank you for contacting us. Please verify if the version you have installed is the official site version or app store version. Only the official site version can be activated via license code. If you download the cleaner one pro from App Store, you will need to do an in app purchase if you want to unlock the full version.
