    Another option that seems to work just fine if you happen to already have your Epic Games Launcer installed on another drive other than C:.

    Create the Epic Games folder in:

    C:\Program Files (x86)

    So you path will be C:\Program Files (x86)\Epic Games.

    Then run the EpicOnlineServics.msi from

    [MY INSTALL LOCATION]\Epic Games\Launcher\Portal\Extras\EOS\EpicOnlineServics.msi

    This way you don't have to go through reinstalled the laucher to where you don't want it.

    Greeting Greg Carmack,

    I have the same issue here is a screen cast of the error in question:

    Like the OP posted, that error details that .net 3.5 is needed, and like the OP I have .net 3.5 installed and yet I still encounter this error. I have reached out to EPIC and was referred to seek help from Microsoft. 

    All the above suggestions were of no help.

    Français :

    La solution au Problème de EOS-ERR-1603. En fait ce soucis viens quand on l'installe sur un autre disque dur que le C.

    Solution : 

    • L’installer normalement sur le disque C:\Program Files (x86)\Epic Games
    • Dans le dossier il y a DirectXredist  / Laucher / Epic Online Services

    - Il suffit de créer sur le disque que l’on souhaite mettre épic games un dossier du nom Epic games et déplacer le dossier DirectXRedist et Launcher dedans Exemple fait un dossier dans D:\Games\Epic Games et coller les 2 dossiers.

    • Laisser Epic Online Service dans C:\Program Files (x86)\Epic Games.
    • Recréer le raccourcis sur le bureau du launcher qui se trouve dans Epic Games\Launcher\Portal\Binaries\Win64
    • Ensuite on peut lancer le launcher et plus aucun soucis d’erreur de EOS-ERR-1603.

    L’erreur venait du faite que le dossier Epic Online Services ne soit pas présent dans C:\Program Files (x86)\Epic Games

    ENGLISH

    The solution to the problem of EOS-ERR-1603. In fact this problem comes when we install it on a hard drive other than C.

    Solution :

    To solve the problem when you want to install the launcher on a hard drive other than The C:

    • Install it normally on the C disc: 'Program Files' (x86) Epic Games
    • In the folder there is DirectXredist / Laucher / Epic Online Services
    • Just create on the disk that you want to put epic games a folder of the name Epic games and move the folder DirectXRedist and Launcher in Example makes a folder in D: Games-Epic Games and paste the 2 folders.
    • Leave Epic Online Service in C: Program Files (x86) - Recreate the shortcuts on the launcher's desktop in Epic Games-Launcher-Portal-Binaries-Win64
    • Then we can launch the launcher and no more error concerns of EOS-ERR-1603.

    Hi Greg Carmack,

    I'm also facing the same problem. I'm getting the same error-message when i try to install the new online-services from epic. If execute the setup manually, located in "EpicGames/Launcher/Portal/Extras/EOS/EpicOnlineServices.msi", it says: Could not access network location EpicOnlineServices\Services. After some research I found that this is may caused, if the shellfolders in the registry point to non existant paths, but I checked that and they all point to existing sources.

    I have brand new Windows 10 System and this seems to be the only issue. EpicGames itself works, also online.

    Would be nice to get a solution for this.

    Best Regards
