What version of L2 u copied? I'v tried to install interlude and scan it but the NCsoft Launcher didn't recognize... So i think its needed to instal other late version to try this but didn't find other place to download some final verison...
I'm trying to run NCsoft Launcher in old version but without succes, i'v tryed to exclue the ''self updater'' too but the launcher didn't run without the archive...
