The League of Legends launcher is the Riot Client — a desktop application made by Riot Games that serves as the front door to League of Legends and every other Riot title. Before you can load into Summoner's Rift, the launcher checks for updates, logs you in, and hands you a big Play button. It also doubles as a news hub, a store, and a home for your account settings, all in one window.
If you've ever wondered why you open something called "Riot Client" to play League, or what the launcher actually does between patches, this article breaks it all down.
What Is the League of Legends Launcher?
The launcher is a lightweight program that runs separately from the game itself. It was originally called the "League of Legends client" but Riot merged it into a unified Riot Client in 2022 so that one app can launch all Riot games — LoL, Valorant, Teamfight Tactics, Legends of Runeterra, and Wild Rift (where available). Think of it as the lobby you walk through before the real game starts.
The Four Things the Launcher Does
-
Section 1: It Identifies the Launcher (The Riot Client Overview)
The Riot Client is the official launcher for League of Legends. When you install LoL, what you're really installing is the Riot Client, which then downloads the full game files. On your desktop you'll see a shortcut labeled "Riot Client" or "League of Legends" — both open the same launcher. Inside, a left-hand sidebar lets you switch between games, while the main panel shows the Play button, your summoner profile, and a banner of recent game content.

Section 2: Key Features Inside the Launcher
Beyond the Play button, the launcher packs in several useful features that are easy to overlook:
- Patch updates. Every two weeks Riot ships a new patch. The launcher downloads and installs these automatically in the background — so most of the time, it's already done by the time you sit down to play.
- News and patch notes. The home screen surfaces champion reveals, balance change summaries, event announcements, and direct links to the full patch notes on the LoL website.
- Loot and shop. You can buy Riot Points (RP), open Hextech chests, craft skin shards, and browse the cosmetic catalogue without ever touching the in-game store.
- Account management. Change your summoner name, check your region, manage privacy settings, and link your Riot ID — all from the launcher's settings menu.

Section 3: How to Download and Install the Launcher
You only need to install the Riot Client once. Here is the process:
- Visit the official leagueoflegends.com website and click Download for Free.
- Run the small installer that downloads — it is named something like RiotClientInstalls.exe on Windows or a .dmg on macOS.
- The installer launches the Riot Client, which then downloads the full game (around 16 GB).
- Sign in with your Riot account or create a free one during setup.
- Once the download completes, click Play to launch League of Legends.
The minimum system requirements for the launcher and the game are Windows 10/11 (or macOS 10.12+), 4 GB of RAM (8 GB recommended), about 16 GB of free disk space, and a stable internet connection of at least 3 Mbps.

Section 4: Common Launcher Issues and How to Fix Them
Most launcher problems fall into a handful of categories, and most are straightforward to resolve:
- Patch download fails. Check your internet connection first. If the connection is fine, try the Repair option in the Riot Client (click the settings gear in the top-right, then select Repair). Disabling your VPN or firewall exception sometimes helps too.
- Login fails or connection error. This is usually a Riot server issue — check the official Riot Games status page to see if there is a known outage.
- Launcher shows a black screen. Try running the Riot Client as Administrator (right-click the shortcut, then "Run as administrator"). Updating your graphics drivers also resolves this in many cases.
- Launcher won't open at all. End any existing RiotClient processes in Task Manager, then relaunch. If the problem persists, a clean reinstall almost always fixes it.

Tips for Getting the Most out of the Launcher
- Let it update in the background. Keep the Riot Client running in your system tray on patch days so updates are ready before you sit down to play.
- Use the launcher's loot tab before the store. Crafting skin shards from Hextech chests is usually better value than buying a skin outright with RP.
- Check the launcher for free rewards. Riot regularly gives away Hextech Chests, event tokens, and limited capsules — the launcher's home screen is where these notifications appear.
- All Riot games in one place. If you also play Valorant or TFT, you only need this one launcher installed — just switch games from the sidebar.
Frequently Asked Questions
Is the League of Legends launcher free?
Yes. The Riot Client and League of Legends are both completely free to download and play. The only costs are optional cosmetic purchases inside the shop.
What is the difference between the Riot Client and the League of Legends client?
They are the same application. Riot merged its individual game launchers into a single unified "Riot Client" in 2022. The LoL-specific game client (the in-match interface and champion select lobby) is a separate process that the Riot Client launches once you hit Play.
Why does the launcher take so long to update?
Each patch is usually several hundred megabytes. The actual download speed depends on your internet connection and whether you're downloading at the same time as millions of other players immediately after a patch goes live. Waiting a few hours often speeds things up significantly.
Can I play League of Legends without the launcher?
No. The Riot Client handles authentication, patch validation, and anti-cheat initialization, so the game will not start without it running first.
Does the launcher work on Mac?
Yes. The Riot Client has a native macOS version supporting macOS 10.12 (Sierra) and later, including Apple Silicon (M-series) Macs. Download the .dmg installer from the official League of Legends website.
Final Thoughts
The League of Legends launcher — officially the Riot Client — is much more than a simple shortcut to the game. It keeps League updated, delivers patch notes and event news, manages your cosmetics and loot, and handles account security, all before you even see a loading screen. Installing it from the official League of Legends website takes only a few minutes, and once it's running you're one click away from Summoner's Rift.
