Windows 10: EOS-ERR-1602 when installing Epic Online Services component to Epic Games Launcher in...

I have been troubleshooting with Epic Games and none of the solutions they came up with worked for me, so the agent suggested I ask Microsoft for guidance since EOS-ERR codes are related to the MSI installer. This is what I have tried: Reinstalling the Epic Games LauncherUpdating Windows 11 and restarting the computerRunning Epic Games Launcher as administratorGranting Read and Write permissions to Epic Games LauncherShutting down Windows Installer Service and then attempting the installRunning the Install and Uninstall Troubleshooter from MicrosoftRelocating Epic Launcher to my main driveEven

EOS-ERR-1603 Epic Online Services install issue

I wanted to share a fix to the EOS-ERR-1603 error that some experience with the Epic Games Launcher and Online Services Install that I haven't seen elsewhere and I hope might be useful.

I followed all of the steps detailed here with no luck: https://www.epicgames.com/help/en-U...es-c5719359691291/eos-err-1603-a5720340831259

Various forums suggested the issue may be due to installing the launcher on a different drive, but mine is in the default location on C:\ so no joy with that either.

However I noticed in the registry there were entries pointing to "C:\Program Files (x86)\Epic Games\Epic Online Services" but the deepest folder didn't exist in my installation, so I created the folder "Epic Online Services" under the "Epic Games" folder:





I then re-ran the installer as described in step 6 on the Epic page linked to above, which in my case is C:\Program Files (x86)\Epic Games\Launcher\Portal\Extras\EOS\EpicOnlineServices.msi and the installer ran successfully fixing the issue.

Hope this helps someone.
