The MapleStory team is currently investigating an issue that prevents some users from updating the MapleStory client due to error message: "This product cannot be installed."


If you encounter this error, open Task Manager and End Task for MapleStory, Nexon Launcher and BlackCipher.

  1. Press Ctrl + Alt + Del to open Task Manager.

  3. For all MapleStory, Nexon and BlackCipher .exe programs, right-click program and select End Process Tree.
  4. Re-open Nexon Launcher and attempt to open MapleStory again.

If that does not resolve the issue, please perform a Repair Installation and a Clean Boot, then try again.
