wasn't using it since 2 years coz had too many problems with detecting it 
today I changed a bit options for l2 so it's working now, still dunno for how long this time
it's for windows vista, no idea if it works on 7 or xp
go to C:\ProgramData\Xfire (it can be hided folder)
open xfire_games.ini and find Lineage II (it's at [4215], just use ctrl+f to find it)
and change it to look like that (or just paste all instead):
now save and close
run xfire (if it was running already better close it and run again)
go to tools/options/games
for me l2 got detected automatically, if for u it won't, then: open Not Installed list and find Lineage II, set it to Manual Detect, click at Browse to find location of l2.exe file, after that just Apply changes and it's done
once u start l2 it should get detected
ps
for windows xp u can try with:
have to change there folder with l2 (LauncherDirDefault) but still dunno if that helps
