Hello there,
I left the pc yesterday night, before I had started downloading and installing unreal the new version.
Today afternoon it has looked like everthing is completed. Unfotunatly the pc was very slow. After severall restarts of the PC I started Unreal Engine 5.
The Engine trys to start but then I get an Errormessage.
It would be nice if someone would give me a helping hand.
Maybe the queastion should be asked in a other kathegorie?!?
Kind Regards
Hello there @Producer1980!
That is unfortunate, let’s try to resolve it. This error and scenario has been encountered a few times through the community, and two methods of resolution stand out:
Solution 1:
- Open the \Engine\Config\BaseEngine.ini file
- Search for the [Zen.AutoLaunch] category and after the “DataPath=” folder path use the old " %APPSETTINGSDIR%Zen/Data " format or any custom path access like “DataPath=%ENGINEDIR%Zen/Data ”
- Test opening a new project
- UE should open with no issues
Solution 2:
- Modify the “BaseEngine.ini” file @ X:\Folder\Epic Games\UE_5.4\Engine\Config >>
Search for "[Zen]"
Change AutoLaunch=true to AutoLaunch=false
- Manually launch “zenserver.exe” @ C:\Users[username]\AppData\Local\UnrealEngine\Common\Zen\Install
- Launch UE5.4 exe
- Click OK on the following windows
- UE should open with no issues
If all else fails:
- Perform a full uninstall/reinstall of all Epic software
- First, uninstall the engine, launcher, asset packs, etc
- Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
- Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
- After that, no elements related to UE should be left in your system
- Now, reinstall UE launcher from scratch, and add any version of the engine you need
