    Since subprocess.Popen WILL escape the spaces with quotes, we need to provide
    them as separate arguments. We don't care about multiple spaces collapsing into
    one, since the point is to just have spaces in the installation path -- one
    would be enough too :)
    This is why we have this weird .split() thingy down there in `/D=...`.

    Note that we do print information to the console, but that's not the stdout stream
    of the subprocess. We make NSIS attach itself to the parent console and write directly there.
    As a result we can't capture the output, so we still have to rely on the logfiles.
