Nero 7 Ultra Edition Instalation Problems

I just got Nero 7 Ultra Edition and I am having problems installing. I used the trial edition I have uninstalled or delated any files that are named Nero that I can find. The only one that I cannot delete is called nerodigitalext.dll.

Nero will not let me install the software because it says I have newer versions that need to be unistalled.

Any sugestions?
