Hello, this was already shared here but I've received a few pms asking me how to do this.
Here is how:
THE CODE
FOR NA:
/launchbylauncher /sesskey /CompanyID: 12 /ChannelGroupIndex :-1 /LoginMode 2 -lang:English -region:0
FOR EU:
/launchbylauncher /sesskey /CompanyID: 12 /ChannelGroupIndex :-1 /LoginMode 2 -lang:English -region:1
you can edit and change the language to German or French if you change the -lang:English for ie: -lang:French
Just remember to add an space before copying the code in the target are in the shortcut.
