Installation always stops the game I do not know what to do. Look at the screenshot http://speedy.sh/46Qf7/dk-error.png

Are you trying to resume the download? If yes, abort it and try to download all at once.

If it still doesnt work for you, you can try to use this Unofficial Manual Installation to download the Client and then just Patch using the Updater.
