What is mega-launcher.exe?

Mega Launcher is the centralized manager for your MegaGames collection, updates, and game launches. It runs as a core UI process and creates separate child processes for each game instance, the updater service, and the downloader. This multi-process design isolates game runtimes from the launcher to improve stability and security.

The launcher uses a multi-process architecture: a main UI process coordinates child processes for each game, update service, and downloader. Sandboxing and IPC isolate game runtimes from the launcher, reducing crashes and security risk.

Types of Mega Launcher Processes

• Launcher Process: Main UI and coordination (1 instance)
• Game Process: Each game runs in its own isolated process
• Updater Process: Updates installed for games
• Downloader Process: Downloads game assets and patches
• Background Tasks: Background sync and launcher services
• Overlay/Plugin Process: In-game overlays or DLC installers

Is mega-launcher.exe Safe?

Yes, mega-launcher.exe is safe when obtained from the official MegaGames installer or MegaCorp's website.
