Nero 7 StartSmart integration

Hi !
I have just installed a new Nero 7 Premium.
I decided to burn my first CD with a new version. So I inserted a new CD into my drive. Then a default system window was displayed. This window always contains a list of available actions depending on what is the contain of a disc. When using Nero 6 I always had Nero actions in this window. This time didn’t see any of them. So I run Nero StaratSmart and its Configuration. There is and option called “Launch the appropriate Nero application when a disc is inserted”. But… this option is not available. So what do I need to have this option checked ?
Thanks for any suggestions and advices.
Cheers !
