LINE Desktop Messenger Application
Line-app.exe is the Windows executable for the LINE Desktop Messenger. It starts the LINE client, handles user authentication, message delivery, and notification delivery, and keeps chat data synchronized with LINE servers. It runs in the background to stay responsive as you use the app.
Line-app.exe initializes the user interface, launches the app's background workers, and maintains secure WebSocket connections to LINE's servers. It loads cached profile data, handles push events, and coordinates message polling for near real-time chat updates.
Reasons it's running:
Yes. Line-app.exe is the official LINE Desktop Messenger executable published by LINE Corp. Always install LINE Desktop from LINE's official site to ensure you have the legitimate binary.
By default LINE Desktop installs to C:\Program Files\LINE and the main executable is Line.exe; you may also find a line-app.exe helper in the same directory depending on version.
Open Task Manager > Startup, locate LINE Desktop, and disable it. You can also adjust LINE settings to prevent startup if supported, then close the app from the tray.
LINE uses a background process to deliver messages and notifications. You can quit from the system tray to stop it temporarily, or disable startup to prevent it from running after reboot.
Check your internet connection, verify sign‑in status, update LINE to the latest version, and restart the app. If problems persist, re-sign in or reinstall.
Update LINE Desktop through the built-in updater in the app or download the latest installer from LINE’s official site, ensuring the publisher is LINE Corp.
