Hello David550,
first of all, thank you for participating, we really appreciate that!
Regarding the old version, we decided to create a successor of the old Cleanup so this new product which is in Beta right now is kind of evolution of the old one.
We would like to replace the old one and all users who already have a valid license will get the new product and they can still use their licenses.
With regards to the license as you described, it seems like a bug because there is an embedded license within the installation package which shall be used automatically during the installation. If the product asks for a license after installation it is not the intended behavior.
We already encountered the same issue and we are working on fix, I will keep you updated once it will be fixed.
Thanks!
