The Epic Games Launcher Setup Wizard ended prematurely
The “Epic Games Launcher setup wizard ended prematurely” error can occur together with an “Invalid drive” message, such as Drive E. This happens because Epic Games was previously installed on a drive that is no longer available, often an external drive that was disconnected or had its drive letter changed.
There are two main ways to fix the problem:
Completely remove Epic Games from the PC using Windows Settings or third-party uninstallers like Revo or IObit, then reboot and run the installer again.
Create a drive with the same letter mentioned in the error (for example E:). You can plug in any USB drive and change its letter in Windows Disk Management to match the missing drive. Then run the installer, remove the old Epic Games installation, reboot, and install Epic Games normally.
