Nero not amongst AutoPlay options when inserting a blank DVD in Vista

First of all, hi to the community!

Now my problem is that when inserting a blank DVD and the AutoPlay window pups up Nero is not amongst the options. This only happens with DVDs, when a CD is inserted Nero shows up. I have selected to add Nero to AutoPlay during installation. Nero is the latest version, OS is Vista Ultimate x64.

How can i add Nero?
