I have just bought samsung nx300m bundled with LR5.
But I have no means to install LR5 on my macbook pro retina 10.9.5.
Samsung says that I should contact adobe korea 02-530-8000.
Whenever I call adobe/kr does not answer my phone call.
Anyway I have download LR but may code from Samsung nx300m didn't work out.
Please let me know how to.

You've very possibly downloaded the CC version and need the standalone version (which is harder to find). Uninstall the version you have and go here for the standalone one:
It helped a lot for me.
