Install with "New" or "All"?

Hi,
Re: Cinema HD
Prior to installing an update you have a choice of “New” or “All”. I usually leave this at “New” and do not toggle across to the right. Does anyone know the difference between these two install options?
Hoping someone can help - cheers

Not familiar with what you’re referring to. I’ve had problems trying to update that app. I click on update, acts like it’s downloading and installing, but then when I try to open the program, it forces me to update all over again. I think I recall, that you have to uninstall it, before you install a new version. Haven’t tried that recently.
