non-Korean Environment (NTLEAS Error)

Locale fix guide for Alicia Online

Some players may encounter this issue while installing, reinstalling, or randomly one day when trying to play Alicia Online. Two common cases:

  • During installation, Windows can display “Trying to launch the game in non-Korean environment.” Installing AppLocale does not always fix it.
  • Out of nowhere the “NTLEAS” error appears when starting the game even if everything worked before.

Wikilicia is here to help you out, hopefully this process fixes your issue.
