Unable to Update Native Launcher

 **I got it to open the launcher somehow, but if I close it I have to go back to the website and use the alternate link to download it again. Any idea on what bug is causing this/how to fix it?

I had a month off from Minecraft while I was moving. When I went to update it tonight (there have been at least 2 major updates) it got 66% of the way through and then froze, bringing up a pop-up that says Unable to Update Native Launcher.

Tried: 

Install update - Failure

Uninstall, restart computer, reinstall - Failure

Repairing - Failure

Remove and try alternate (msi) link - Failure

I have attached the updateLog.txt and now a nativelog.txt. There is no launcher_log.

 

Can somebody help me with this?
