Epic Online Service - Installer won't install

[Sentinel]

Can someone help me. When I try to install the "new" EOS-Installer, it installs every file, register the service, but then does a rollback and deletes everything again.
Windows event log says it exits with code 1603.
.Net 3.5 is installed and working, I created the folders under "C:\Program Files (x86)" by hand, but the installer deletes them again. I tried to clean the registry from epic entries, but no luck. The "old" EOS installer did work, but the game couldn't find the EOS service.

Same issue here, EOS is a joke...

Thats exactly my problem aswell, so stupid that it just reverts the installation, the game worked fine on the first start, but the second time i started it, the issues happened.

The only way i get to play now is if i make the ini change and delete EOS from the game folder but then you lose access to your DLCs and the pro stuff.

start with the basics.

1. Make an exclusion rule for the steam folder in your antivirus
2. Disable OneDrive
3. Verify the integrity. (they told people to do this even if they were not having issues after the update)

since no one knows what apps you run on your PC or how you maintain it, you should make sure there arent any other third party apps interfering with steam or messing with file/folder permissions.

I have the same problem. And that's only because of Epic Games, this company has only one goal: to destroy gaming as we know and love it, that's the reason for the cooperation with Disney because they do the same thing with films. What a messed up world where Fortnite is still played by thousands but Dead Space doesn't even get a second part because it sold too poorly.

This worked for me:
- download and install the Epic Launcher (comes with the correct EOS installer file)
- close the Launcher/Update
- start the game on Steam (EOS installer pops up)
- quit out of the game & uninstall the Epic Launcher (when the window for EOS pops up click "No")

Yep, worked for me as well. The fact that I waited for the game to come out on Steam just to have to download EGS anyway is a late unfunny April Fools joke...
If I wore a tinfoil hat I'd say that Timmy did this on purpose but whatever...
At least I didn't have to make an account and could safely uninstall EGS after that (hopefully it didn't leave many traces).
Here, have some of my points my friend.

I generated a logfile for the installation and found an error:

 MSI (s) (10:1C) [14:22:57:095]: Executing op: ActionStart(Name=InstallWindowsService,,)

CustomAction InstallWindowsService returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 14:22:57: InstallFinalize. Return value 3.

It seems it fails to install the service and does the rollback afterwards. I'll check if I can fix it somehow.

First possible fix: disable rollback
1. open Regedit
2. navigate to HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Installer (or create key, if not present)
3. change DisableRollback to 1 or create DWORD DisableRollback and set it to 1
4. install EOS from game directory
5. remove changes from registry or set DisableRollback to 0

The installation will now work and the EOS service will also be installed an can be started. In my case I still get the "could not find EOS from the game", but maybe it works for someone else.

its work ?

Second possible Fix: Install Epic Games Launcher (no need for Epic Account)
1. Download Epic Games Launcer from Epic
2. Install it and allow everything it asks for
3. Let it update and again allow everything
4. Minimize or close the Launcher
5. Game should run now

I tried to uninstall (only) the Epic Games Launcher and deny changes to Epic Online Services through that deinstallation, but no luck so far, the game tells me, that it couldn't find the Epic Online Services.

It seems that the EOS-Version, that comes with the game is missing some prerequisites, which comes with the Epic Games Launcher.

I just wonder why the installation works for some folk but not for all. maybe the players with EGS installed on their pc got no issues? I don't have it and no account.
