Product Key not past to DVD

The software I use TuneUp Utilities for years but there are little nuances, so the product key the second time (second purchase) does not match the DVD in the package.
It is the message wrong product key, transitional great !!!!!!!!
Again and again I have to download to install the Internet and the software, why ??
Also, the menu is not the simplicity of its predecessors, unfortunately it is often the case that something needs to be bought and then let's set up everything else, here also why ??
It went well for years and has found everything, now it's like a new software,
I can also change the same and looking me another software THANK AVG.
