Hello Driver Booster User，
This is IObit Driver Booster Support Team.
Please note that Driver Booster 6 Steam version no longer needs license code to activate the PRO version. Driver Booster will automatically recognize whether you has purchased DLC (Pro) after it starts.
You may reinstall Driver Booster 5.
Thanks for understanding.
