Problem is that if i install nero without command line parameters, it installs in Spanish language, but if i add some command line parameters, language installation get no changes, so i think i need to add the /language parameter to change that settings again. I've tried to use this command with words like "spanish" "español" "esp" "es" "sp"... but still havin' the same problem. Should i try another .exe version? do you know where can i get the exhaustive command line parameter list or a /language command complete description? should i try to apply language command on nero's installator or in nero's update file?
