How to Install and Troubleshoot ES Script LoL

In this guide, we’ll walk you through how to install ES script LoL, update the ES version, and troubleshoot common errors. This comprehensive step-by-step guide ensures that you can install ES for League of Legends without any issues and avoid common pitfalls that may arise during the process.

Requirements

AIO Runtimes: Download the Visual C++ Redistributable Runtime Package All-in-One. Extract the file to a folder and run the install-all file. This installs all required runtime libraries to ensure your system can run ES for LoL without any errors. Missing runtimes often lead to performance problems or application crashes, so this step is essential.

.NET Framework: Download and install the .NET Framework 4.8. This framework is required for running the ES script for League of Legends since it is developed using .NET technology. Without this crucial software, you may face issues when trying to execute the script or encounter unexpected crashes.

Disable Defender: It is recommended to disable Windows Defender during the installation of the ES script. You can do this easily by downloading Defender Control, a tool that allows you to turn off the Defender with a simple click. This prevents the security system from flagging or blocking the ES script when you attempt to install ES script LoL.

Updating and Troubleshooting ES

Step 1: Updating ES

To keep your ES running smoothly, always ensure that you’re using the latest version. Start by deleting the old version of ES, then download and install the newest version available. There is no need to delete the cache during this process. Following this step ensures that you have the most up-to-date features and fixes for any bugs that may arise when you install ES for League of Legends.

Step 2: Issues With Old Versions

If you’ve used an older version of ES or are facing performance issues, it’s always a good idea to reboot your computer. This helps refresh your system and can clear out any temporary glitches or conflicts that could prevent you from running the ES script for League of Legends efficiently. Rebooting is often an overlooked but effective troubleshooting step.

Step 3: Troubleshooting RunDLL Errors

If you encounter a RunDLL error or nothing happens when you try to run ES as an administrator, it may be due to your file’s location. To fix this, move the ES file to the C:\ directory and try running it again. This often resolves file path issues that prevent successful execution. Ensuring that the file is in the correct location can help you avoid complications when trying to install ES script LoL.

Disabling Security Features

To prevent any conflicts when you install ES for League of Legends, make sure to disable all security features, including:

• Firewall (Private, Public, and Domain)
• Microsoft Defender Firewall
• Windows Core Isolation (disable this and restart your PC)

Disabling these features is important because security tools can sometimes falsely detect or block parts of the script, leading to installation failures. After disabling these features, restart your computer to ensure everything is set properly before continuing.

IMPORTANT: Always start the build file as an administrator before opening the League of Legends client (LCU). Do not run ES while the game client is open. If you close LCU, restart ES before launching the game again to avoid issues.

Step-By-Step Guide to Running ES

Step 1: Close Any Riot Process

Before you install ES for League of Legends, make sure that all Riot-related processes are completely closed. This prevents detection and minimizes the risk of getting banned. Failing to close Riot processes could interfere with the ES script and compromise the entire setup process.

Step 2: Run Build.bat As Administrator

Right-click the Build.bat file and choose “Run as administrator.” This opens a command prompt window along with the ES login interface. These windows are necessary for running the script, so do not close them while they are active.

Step 3: Select Update Server

If you’re an international user, select the SEA update server. For users in China, select CN. This ensures the script connects to the correct server for updates.

Step 4: Open League of Legends Launcher

After logging into ES, open the League of Legends launcher and access the game lobby. Once you are logged in, the ES interface and CMD window will disappear automatically. This indicates that the script is running properly in the background.

Step 5: Automatic Injection

The ES script will automatically inject itself once you enter the game. If you restart your computer or update the ES version, be sure to re-run the Build.bat file to ensure the script continues working correctly. Following these steps completes the process of how to install and run the ES script for LoL.
