Unable to Update the Minecraft native launcher

I missed my Minecraft

there is a easy fix for this all you need to do is go to where the launcher is based

1. Windows Based
   C:/Program Files (x86)/Minecraft/

once there if you have the navtivelog.txt you will see it says the Launcher Directory it is directed to a foler that does not exist so just make the folder in the formentioned folder

i just did this:

http://launcher.mojang.com/mc/launcher/win/96a22390a0b1d3c58706b6ce17135982e6d2d6a0/Minecraft.exe
V
downloaded the file
V
It all worked afterwards!!

todas la saluciones que me han dado no me sirven por favor darme otra solucion ya que voy mas de un mes con este problema y e intentado muchas maneras de arreglar pero ninguna me la soluciono ni siquiera esta y lo peor es que es la pagina oficial. 

Ps: denme alguna solucion 

gracias.
