Almost every recent patch for League of Legends has caused strange problems for some of the users who’ve installed it. Some brought the error code “004” and we have the solution for you.

Every now and then, Riot releases a new patch for League of Legends to fix bugs and improve the player experience. Even though the purpose of patches is to make the game better, installing one of these updates can turn into a nightmare for some. Namely, as soon as the game finishes installing the patch, it becomes unresponsive on launch and players are not able to pass the loading screen. Even worse, nothing but the dark screen appears on start. This problem is known as ‘error 004‘.

Both players and the development team have been trying to deal with these issues for quite some time, but somehow it re-appears with almost every new patch. Unfortunately, there’s no confirmed solution for this issue, but some users found at least something that might be of help.

One player reported on the forums that reinstalling the game with the Hextech Repair tool managed to solve the error 004. In case you’re not familiar, this tool is used for various troubleshooting purposes in League of Legends, including reinstallation, firewall management, repatching, and more.

You can download the Hextech Repair tool from this link — it’s completely free of charge. When you install and open it, you’ll notice the option to reinstall the game. Reinstall League of Legends with this tool and see if the error still persists after.

We also have to tell you that this is not a confirmed solution and it only worked for some players who reported it. So, we can’t guarantee you it will deal with your problem.
