// Although there's not a strongly typed error for this in go-winio,
// lots of people are using the default configuration for the docker
// daemon on Windows where the daemon is listening on a named pipe
// `//./pipe/docker_engine, and the client must be running elevated.
// Give users a clue rather than the not-overly useful message
// such as `error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.25/info:
// open //./pipe/docker_engine: The system cannot find the file specified.`.
// Note we can't string compare "The system cannot find the file specified" as
// this is localised - for example in French the error would be
// `open //./pipe/docker_engine: Le fichier spécifié est introuvable.`
