I just recently had to reinstall Windows 11 and now the Epic Launcher always fails during its installation process. I had the same Windows 11 Home key before I needed to do the re-install and Unreal Engine worked just fine. Currently all of my other programs have loaded and are working correctly (Unity, Wwise, FMOD, Steam, GitHub Desktop, etc.)
Chanced upon this article and began wondering why “Epic Games Launcher Wizard ends prematurely because of an error”.
Primarily this error is spreading throughout everyone’s systems. And no rectification has been thoroughly founded as of now.
Hello everyone!
I ran into this problem and tried absolutely everything mentioned in the forums, including the Microsoft Store where the installation also failed.
My solution was to find another computer where I had a 2021 Epic Launcher (version 13… something, if I remember correctly), and run that installer. It finally worked!
In other words, you need to use an older launcher to avoid the issues with the current one.
Ideally, Epic would fix this, but it was the only workaround I found.
Hello, I had this problem with the current windows installer off of Epic’s website on Windows 10. The log files in my user folder (AppData\Local\Epic Games\Epic Online Services\EOSInstaller\Logs) showed it was trying to create an EpicOnlineServices.msi file in my user folder but my username was incomplete. It stopped at a space in my username. I created another user on my windows computer called “test” with administrative rights and was successful with the install. I’m pretty sure it was an issue with the space in in my windows username that the installer choked on.
I hope this helps someone and of course would like Epic to fix it.
