Last I checked, Nero 7.x was buggy and giving a fair number of people various headaches. They may have fixed it since then, but it is rather bloated and contains a lot of other stuff you don't need. You're also going to need a new license for that - the license for 6.x isn't compatible with 7.x.
I'd just stick with 6.6 if I were you. The latest version of 6.6 was 6.6.14 when I checked Nero's website last week. If the version that came with your 4167B isn't that new, you can download a free upgrade to 6.6.14 from the Nero website.
