my sister have nero on her computer, is here anyway to put it on cd and later put it on my cd if so how do i copy it
Answers: Nero is commercial ($$$) software, so the answer is: No, not justifiably.
Google for: Deep Burner or disc burner XP Pro
Both are free and work much resembling Nero.
DeepBurner and CDBurnerXP are proprietary (closed source software). Try the friendly source Infrarecorder.
