None of this 100% worked. This is the only way I could get it to work:
Step 1: hax the “BaseEngine.ini”
@ X:\Folder\Epic Games\UE_5.4\Engine\Config >>
Search for "[Zen]"
Change AutoLaunch=true to AutoLaunch=false
Step 2: Manually launch “zenserver.exe”
@ C:\Users[username]\AppData\Local\UnrealEngine\Common\Zen\Install
Step 3: Now launch UE5.4 exe lolz
Step 4: Click Ok to remove 3 popup messages (+1 bonus popup).
Yer done. Don’t forget to like, subscribe, and ring that bell.
