Fix: “Epic Games Launcher Setup Wizard Ended Prematurely” Error

The error “The Epic Games Launcher setup wizard ended prematurely” indicates that the installation process was unexpectedly halted and could not be completed. This issue often arises due to missing system components or software conflicts. The primary culprit is frequently the absence of the .NET Framework on your computer.

Furthermore, corrupted installation files, insufficient administrator privileges, or conflicts with previous installation files can also lead to this error. The following steps should help you troubleshoot and fix this problem effectively.

1. Run as Administrator

Running the installer with administrator privileges can help bypass permission-related errors. Sometimes, Windows requires elevated permissions to install new software, which might not be automatically granted without this step.

1. Locate the installer file, right-click on it, and select “Run as Administrator“. This action ensures that the installer can modify system files as needed during installation.
   

2. Install .NET Framework 4.8

The .NET Framework is crucial for a wide array of applications, driving functions like memory management, security, and system integration. Many software, including the Epic Games Launcher, rely on this framework to function correctly.

1. Type “Turn Windows Features on or off” into the Search Box and open it. This opens a list of optional Windows features.
   
2. Ensure that the box next to “.NET Framework 4.8” is checked. This step activates or installs the framework if it’s missing from your system.
   
3. Follow the on-screen instructions to complete the process. An active internet connection might be required if the necessary files are not locally available.

3. Delete Any Old Epic Games Folders

Leftover files from previous installations might cause conflicts with the new installation. Removing these can prevent potential conflicts and clear the path for a fresh installation.

1. Press CTRL + E to open File Explorer.
2. Navigate to the C drive or the location where you previously installed Epic Games.
3. Look for the Epic Games folder, right-click on it, and select delete. This removes any outdated files that might interfere with the installation.
   
4. Confirm the deletion by clicking Yes. This step is crucial to ensuring all old files are removed.

4. Execute the Installer Using msiexec

The msiexec.exe utility is a powerful command-line tool that allows you to install software packages. It helps in bypassing common user interface issues and ensures that all necessary permissions are handled correctly.

1. Press CTRL + SHIFT + ESC to open the Task Manager.
2. Select File > Run New Task.
   
3. Type “msiexec.exe” in the dialog box and put path to your Epic Games Installer right next to it in double quotes. Check example: msiexec.exe “C:\Users\Your Username\Downloads\Programs\EpicInstaller.msi”
4. If you do not know exact path of your installer, simply locate it and right-click on it, then select Copy as Path.
   
5. Once you have the path put it in the Task Manager like this:
   
6. Check the box for “Create this task with administrative privileges“.
7. Click OK to initiate the installation process.
8. Observe if the installation proceeds without the error.

5. Change Installing Destination

Sometimes, issues like insufficient disk space, damaged disk sectors, or limited write permissions can interrupt installations. Attempting to install the software on a different drive can often bypass these issues and facilitate a successful installation.

6. Disable Antivirus

At times, antivirus software might mistakenly flag installer files as threats, blocking the installation. Temporarily disabling your antivirus software can clear the way for a smooth installation. However, remember to re-enable it afterward for ongoing protection.

1. Search for the Microsoft Store in the search box and launch it.
   
2. Type “Epic Games Launcher” into the search bar.
   
3. Click Get > Install to begin the download and installation process directly from the store.
   
4. The installation will automatically start once the download is complete.
