Does anyone know if it's possible to only install a file (or component or feature) if a particular file doesn't already exist on the target machine?
I want to install a file but only if it doesn't exist already on the target machine.
So I need to somehow detect if the file does exist and if it does I don't want to install it again. If it doesn't exist I do want to install it. I won't necessarily know where on the machine the file might be>
