Hextech Repair Tool (Now Riot Repair Tool) Guide
Quick note on the name: Hextech Repair Tool has been rebranded as Riot Repair Tool (RRT) by Riot Games. The functionality is identical — only the name changed. If you’ve seen both names and wondered if they’re different tools, they’re not.
Riot Repair Tool (RRT), formerly known as Hextech Repair Tool, is a free diagnostic utility developed by Riot Games. It addresses common technical problems in League of Legends and other Riot titles — including FPS drops, packet loss, server connection errors, game loading failures, stuttering, and high latency — by running automated checks at the network and game file level.
Under the hood, RRT operates as a lightweight diagnostics program. It checks your DNS resolution, evaluates your firewall rules, tests ping to Riot game servers, synchronizes your system clock, and verifies game file integrity. It doesn’t modify personal files or collect personal data beyond the diagnostic logs it generates for support purposes.
The tool also supports all current Riot Games titles — not just League of Legends. If you play VALORANT, Teamfight Tactics, or Legends of Runeterra, RRT can help troubleshoot those games too. We tested the steps in this guide on Windows 11 to make sure everything is accurate.
How to Download Riot Repair Tool (Hextech Repair Tool)
Download Riot Repair Tool directly from Riot Games’ official support page. Versions are available for both Windows and macOS — select the one that matches your operating system.
- Windows: Download the
.msiinstaller and run it. Installation completes quickly with no manual configuration required. The tool is ready to launch immediately after. - macOS: Download the macOS version from the same support page. The installation process is similar, though log file output locations differ from Windows (see the log files section below).
Tip: If the installer won’t run, right-click it and select Run as administrator. The tool requires administrative privileges to modify firewall rules and DNS settings. Also make sure you’re downloading from the official Riot support page — third-party download sites may host outdated or modified versions.
How to use Hextech Repair Tool
- Close League of Legends (or whichever Riot game you’re troubleshooting) completely before launching the tool.
- Open Riot Repair Tool.
- Select the region of your game server from the dropdown.
- Enable the repair options you want to apply. If you’re unsure, enable all options except Disable Firewall — use the firewall exception option instead (see the feature breakdown below).
- Click Start and wait for the process to complete.
- Restart your computer, then relaunch your game to check if the issue is resolved.
Which options to use for common problems
Not sure which options to enable? Use this as a quick reference:
| Problem you’re experiencing | Recommended options to enable |
|---|---|
| High ping or packet loss | Ping test, Use public DNS servers, Synchronize system clock |
| Game won’t connect to server | Ping test, Make firewall exceptions, Use public DNS servers |
| Game won’t launch or crashes on load | Repatch game files, Reinstall all game files |
| General issues (unsure of cause) | All options except Disable Firewall |
What each feature does
RRT includes a range of repair and diagnostic options. Here’s what they actually do, grouped by category:
Network diagnostics
- Run a ping test — Tests the connection between your computer and Riot game servers to identify latency or packet loss.
- Use public DNS servers — Switches to public DNS to bypass slow or unreliable DNS resolution, which is a common cause of connection errors.
- Automatically assign DNS servers — Lets the tool select the best DNS configuration for your setup.
- Show known problems in your region — Checks Riot’s status page for active server-side issues so you know if the problem is on their end.
Game file repair
- Repatch the game by force — Useful when a failed or corrupted update leaves the game in a broken state. Forces the client to re-download and apply the latest patch.
- Reinstall all game files — A more thorough option that replaces all game files from scratch. Use this if repatching doesn’t resolve the issue.
System configuration
- Synchronize your system clock — Corrects time sync issues that can cause authentication or server connection failures.
- Make firewall exceptions for the game — Adds League of Legends or your Riot game to the Windows Firewall allowed list without disabling the firewall entirely. This is the recommended option for firewall-related issues.
- Disable your firewall — Not recommended. This may temporarily resolve connection issues but leaves your system exposed. Use the firewall exceptions option instead.
- Gather log files — Collects detailed diagnostic information about your system and game installation. See the section below for how to use these logs.
How to gather and use log files
After RRT finishes running, it automatically generates a folder of log files (on Windows, this folder is created in the same directory as the tool; on macOS, the location may vary). These logs contain diagnostic details about your system configuration, network status, and game installation.
If the tool doesn’t resolve your issue, these log files are your next step. Submit a support ticket to Riot Games and attach the log files to your request. This gives the support team the technical detail they need to diagnose your specific problem faster.
Is Riot Repair Tool Safe?
Yes. Riot Repair Tool is developed and distributed by Riot Games — the same company behind League of Legends and VALORANT. You can verify this by downloading only from Riot’s official support page. If you want to independently verify any downloaded file, you can check it using VirusTotal.
The tool requests administrator privileges to do its job — specifically to modify firewall rules and DNS settings. It does not access personal files or transmit personal data beyond the diagnostic logs it creates for Riot support purposes.
The most intrusive option in the tool is Disable Firewall. Skip this option unless Riot support specifically instructs you to use it. The Make firewall exceptions option achieves the same connection fix without exposing your system.
Frequently Asked Questions
Is Hextech Repair Tool the same as Riot Repair Tool?
Yes, they’re the same tool. Riot Games rebranded Hextech Repair Tool to Riot Repair Tool (RRT). The functionality hasn’t changed — only the name. If you’re looking for the Hextech Repair Tool download, the current version is listed on Riot’s support page under the Riot Repair Tool name.
What games does Riot Repair Tool support?
RRT supports all Riot Games titles, including League of Legends, VALORANT, Teamfight Tactics, and Legends of Runeterra. The tool was originally built for LoL, but it now works across the full Riot Games library.
Where do I download Riot Repair Tool?
Download it directly from Riot Games’ official support page. Both Windows and macOS versions are available. Avoid third-party download sites — they may host outdated or modified versions of the installer.
What should I do if Riot Repair Tool doesn’t fix my issue?
After running RRT, locate the log files it generated and attach them to a Riot Games support ticket. On Windows, the log folder is created in the same directory as the tool. On macOS, check the tool’s output for the exact path. The logs give Riot’s support team the diagnostic detail needed to investigate your specific issue.
Is it safe to use the Disable Firewall option?
It’s not recommended as a permanent fix. Disabling your firewall removes a layer of system protection and should only be done temporarily if Riot support specifically asks you to test with it. For most connection issues, use the Make firewall exceptions option instead — it adds your Riot game to the allowed list without turning off the firewall entirely.
Does Riot Repair Tool work on Mac?
Yes, RRT is available for macOS. Download the macOS version from the same Riot support page. The tool works the same way on Mac, though the log file output location differs from Windows. Check the tool’s interface after it runs to find the exact path to your log folder on macOS.
What does Riot Repair Tool actually do to my computer?
RRT runs diagnostics at the network and system level. It checks DNS resolution, evaluates your firewall rules, tests ping to Riot game servers, synchronizes your system clock, and verifies game file integrity. It doesn’t modify personal files or collect personal data beyond the diagnostic logs it generates. Think of it as a targeted health check for your Riot game setup — not a system-wide optimization tool.
Why won’t Riot Repair Tool install?
The most common cause is missing administrator permissions. Right-click the installer and select Run as administrator to fix this. If the installer still fails, check whether your antivirus software is blocking it — temporarily disabling real-time protection during installation can help. Also confirm you downloaded the installer from Riot’s official support page, since corrupted downloads from third-party sites are a frequent cause of installation failures.
If RRT runs successfully but your issue persists, submit a support ticket to Riot Games with the generated log files attached. That’s the fastest path to a resolution for problems the tool can’t fix automatically.
