    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.

    Worked for me, thanks!

    Кому интересно, я просто переустановил в C:\Program Files (x86)\Epic Games и тем самым во время установки появилась папка Epic Online Services. И вот главное этой папке находится там же, а всё остальное можете переместить туда, куда вы хотите.

    Hi everyone,

    i got a reply from Epic. They told me, that they forwarded this problem to the development and hope it can be fixed in a future update. Seems like this is all we get up to now.

    Best regards
