Hi, I need some help. I find the help in InstallShield just about the most non-user friendly ever I am sorry to say. It just is completely mystifying.

What I am trying to do is only install certain files if (a) it is a brand new installation or (b) it is an upgrade and the files already exist.

(b) might sound counter-intuitive but it is because in a previous install the user might have moved these files somewhere else and we don't want two versions hanging around. If they moved them we have no way of knowing where they moved them so we can't just go to that directory and install them.

Any help gratefully received. Please let me know any thoughts at richie.morgan@gmail.com.

Thanks!
