If you are experiencing Net Error 1.203#19000 / 1.203#19001 / 1.203#19002 (for players on Epic or PC), please try the following steps:
- Uninstall Epic Games Launcher
- Go to Epic Games website and redownload the launcher
- Install the launcher
- Launch or install KO City depending on what service you're using (Epic or Steam)
- If Epic Games has issues installing (notably the Epic Games Online Service program), install the Epic Launcher into another folder or drive letter. This should work around the error and get it installed
- If you don't want to install KO City through Origin, and you need to link accounts, you can install KO City through Epic instead. Once that's done, you can cancel the download.
