Failed to Update

  • I just downloaded the game the other day because my friends got to play LoL, but today I came home to a patching error and have no idea how to fix :c

    It stays at 33% then says "Failed to download or extract all update files"

    Help pleeease D:
  • Hey there!

    Sorry to hear you guys are having problems with this. Luckily, this is usually just a failed self-patcher issue that is fixed up rather easily.

    The first and most common solution is to force the patcher to repatch itself. You can do this by deleting this folder:
    C:\Riot Games\League of Legends\RADS\projects\lol_launcher

    Many players also fixed this problem by disabling the UAC(Windows Vista and Win7 Only)

    If that doesn't work, try doing the following:

    Manually Updating/Installing the .Net Framework 3.5

    Making sure you are running the game as an administrator.
    a) Right-Click on the short-cut
    b) Select the properties tab
    c) Check the box labeled "Run as administrator"

    Failing all of that, i would suggest sending in a support ticket to our Technical Team Here and they will be able to help you better in a one-on-one basis
