Last evening the Minecraft launcher updated and seemed fine. This morning it tried to update again and this time gave an error of "Problem moving C:/Program Files (x86)/Minecraft/tmp/tmplauncher.tmp to MinecraftLauncher.exe with error code 5." I have attempted several times w/ the same error and even went as far as reinstalling the game from the Minecraft website only to get the same message. Any advice on how to disable the update, rollback to previous update, or correct the problem would be helpful.
