Activating AVG PC Tune UP

Hello, Jim.
You must have installed the unlimited devices version of AVG TuneUp which does not require a license to activate it. So there won't be an option to enter a license number. Please uninstall it as per the steps in this link. Then refer to instructions in this article to download and install AVG PC TuneUp using the key.
