EOS-ERR-1603 Epic Launcher and EOS Installer automatically delete Epic Online Services Windows 10 during installation

Hi @bnhrsch !
Since you followed the troubleshooting guide, here are some other things you can try.

  • Make sure to run the installer as administrator and check if you have fully permissions on the installed folder.
  • Check your windows update
  • Disable antivirus/Firewall for the installation
  • Install both versions of Microsoft Visual C++ x86 and x64
  • Try installing on a clean different location.
  • If nothing works out re-install Epic Games launcher

Hope it helps
