So after New Horizons patch, game forces you to open patcher every time you want to start it from elementclient.exe.
You can bypass it, so it will start directly. To do this:
1. Right click on elementclient.exe in EPW/element/ directory and create a shortcut of that file.
2. Right click on elementclient shortcut and choose Properties (last option on the bottom).
3. In the target field add at the end:
startbypatcher. Just like that:
That's it. From now just run elementclient shortcut so it will skip the patcher window.
I added this as a batch file to attachment as well. It has to be started from the EPW/element/ directory though.
