"Download from Internet" shouldn't care in the least whether there is a
Cygwin installation present or not. It should only care about the files in
the local directory tree.
Currently, if you install a file, it will then realize that version is
present and not default to downloading it again. If you don't install, the
chooser doesn't know about the version you downloaded so it will keep
downloading it until it is installed.
