LOL Classic Download Slow? How to Fix Slow League Client Updates

League of Legends Classic will launch on July 29, 2026 with Patch 26.15, bringing players back to a classic League experience. However, when you update the League client at launch, you may encounter LOL Classic slow download speeds, stuck updates, or long installation times.

In this guide, we will explain why LOL Classic updates may be slow and provide practical fixes to help you complete the update and enjoy smoother gameplay.

Tip: Before the official release, the mode was already available on the PBE. If you're still looking to try it early, check out How to Play League of Legends Classic on PBE.

Why Is LOL Classic Download So Slow?

Since LOL Classic runs through the existing League of Legends client, slow downloads usually happen during Riot Client updates rather than a separate Classic installation. If your update is taking too long, getting stuck, or downloading slower than expected, the issue may come from the following factors:

• Large League update: LOL Classic requires updates to the existing League of Legends client. If your game files are outdated, Riot Client may need to download a large patch before you can access Classic mode.
• Launch Traffic: When LOL Classic launches, a large number of players may update their League clients at the same time. High demand can slow down LOL patch downloads and cause longer waiting times.
• Network Routing Issues: Your connection route to Riot's update servers can affect download performance. An unstable route may cause slow speeds, connection drops, or inconsistent download progress.
• Background Apps: Other applications using your bandwidth, such as Steam updates, cloud sync tools, or browser downloads, can reduce the speed available for Riot Client.
• Client Problems: Temporary Riot Client issues, corrupted cache files, or permission errors may cause downloads to freeze, restart, or get stuck at a certain percentage.

How to Fix LOL Classic Download Slow (6 Methods)

Before playing LOL Classic, players need to make sure their League client update finishes successfully. If your Riot Client update slow, try the following fixes to learn how to download lol classic faster based on the issue you are experiencing.

Fix 1. Restart Riot Client

Sometimes Riot Client may fail to maintain a stable update connection. Restarting the launcher forces it to reconnect and refresh the update process.

• Download stuck at 0%
• Update progress does not move
• Riot Client becomes unresponsive

Steps:

1. Close Riot Client completely.
2. Open Task Manager (Ctrl + Shift + Esc).
3. End any remaining Riot Client or League processes.
4. Restart Riot Client.
5. Start the LOL Classic update again.

If the download speed returns to normal after restarting, the issue was likely caused by a temporary client problem.

Fix 2. Run as Administrator

If your League of Legends Classic download slow or gets stuck after downloading, try running Riot Client as Administrator.

1. Close Riot Client.
2. Right-click the Riot Client shortcut.
3. Select Run as administrator.
4. Start the League update again.

Steps:

1. Press Ctrl + Shift + Esc to open Task Manager.

4. Restart the League update.
