I install the Epic Games launcher and I get this, I have formatted the PC, changed from Windows 11 to 10 and it still does the same thing, does anyone know why?
That seems like a general WIndows installation error. General Windows troubleshooting then? Restart? Run as admin? Uninstall any previous versions and try again?
Maybe the windows decimal setting is conflicting with unreal?
Check windows => Control Panel => Region => Additional Settings (button) => Decimal Symbol
It works with , as a symbol. Maybe Spanish has a dot or different symbol by default?
