Hello HENRY_BOSKAR. I understand you are witnessing the "Bluetooth License file is not found" error, after using a system cleaning tool. I want to do my best to help you! I need to inform you that running registry cleaning tools can cause this issue, since it could remove the requirements to use Bluetooth properly. I would reinstall the Bluetooth/wireless driver for this computer. You can reference this website as it contains suggestions on how to do this.
Please respond after this is complete so I know the results. I'm only here to help!
