DVD Burner Program Question

I’m asking this question for a friend. She is using an computer that was given to her and wants to install Ashampoo Burning Studio Free. Currently, she has both Sonic MyDVD and and Nero Essentials installed on it. Does she have to uninstall them first? Also, she doesn’t uninstall them, will they conflict or cause problems with Ashampoo?

I don’t know all those programs specifically, but burning programs probably won’t conflict. If one or all of them create a new virtual drive (I believe Alcohol 120% does this), then those might be an issue if multiple programs turn some on.
