When i go to launch the launcher, it comes up with "unpacking launcher", then shortly after a message pops up saying unable to update the Minecraft Game Launcher

AS i explained in the summary it just doesn't open anything. I have tried opening the logs and it says, "error 5" if that means anything. I have also tried to repair the minecraft launcher by re-downloading it, but that has also failed me. Here's a screenshot. https://gyazo.com/1515446faf4c2a03e51937ffaaad8124
