  • Hi Jerret and Tony,

    It sounds like you're both having issues starting up the game client after patching. This can be caused by a failed patching attempt and there are several ways to fix it.

    First, you can try executing the Repair feature in our Game Patcher--if you can load the Game Patcher. There should be a Cog icon on the corner which will lead you to a Settings Menu; once you're there, you can execute a repair.

    Second--if the first step didn't work or you cannot launch the Game Patcher--you can try the following to force a re-patch:

    1) Go to your Riot Games folder (C:/Riot Games/League of Legends)

    2) Open the following directory:

    C:\Riot Games\League of Legends\RADS\projects\lol_air_client\releases\<hig hest number folder>

    3) Delete the following files:

    - releasemanifest
    - S_OK

    Third, you can try just deleting the following folder in C:\Riot Games\League of Legends\RADS\projects\ to force a re-patch:

    - lol_air_client
