There are a number of Nero 8 offerings but I’m guessing you downloaded Nero Ultra. If you are using it as a trial version, you have 15 days to evaluate the product. If all you want is Nero Express, there are cheaper ways to go with Nero (http://www.surpluscomputers.com/store/main.aspx?p=SearchBody&search=nero). Regardless, many Nero users would rather have Nero Burning ROM as their main Nero program.
If you have installed the Ultra version, the screenshot should meet your needs. Or, you could reinstall the program first using the appropriate clean tool remover (http://www.nero.com/enu/downloads-cleantools.html) and click on custom installation. Select that which you wish to install.
