    Same issue as everyone above and indeed have Epic like any normal person installed on another drive then the system.

    This solution worked like a charm, thank you!

    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!

    Thing is why was the 'fix' necessary ?

    How can they make such a great engine and something so trivial as a different 'install directory' hang up install of something so trivial, as well ?

    Utter nonsense, like Microsofts non response to issue in mail, where trying to click on something and these giant windows (url) pop up making it , far too often, impossible to click on url .

    thx
