I had the problem ever before, the updater was only on my laptop
Probably just a bug. Try to delete your whole Minecraft folder and reinstall Minecraft again, it should work great.
But what about the "versions" and "save" folder?
If you have important worlds that you want to save, I would put the folder with the saves on your desktop and replace it after reinstalling with the save folder of the new minecraft
And which file path do you mean in% appdata & or the: C: \ Program Files (x86) \ Minecraft
Well, now Minecraft does not work anymore.
Now comes the bug: Unable to update the Minecraft Native Launcher
You misunderstood me. You have to delete the whole Minecraft folder
At the same time, press Windows key and the letter R, type appdata and delete the whole .Minecraft folder. Then you just go to the Minecraft website, download the installer and install Minecraft as usual.
I have yes
Does not work either.
I could help you on Teamspeak or Skype if your problem has not been solved yet.
Ok and when on teamspeak
