Download
One executable. It signs you in, downloads the menu, verifies it, and loads it into the game. There is one build for every plan; what unlocks inside it is decided by your plan.
1. Create an account
Register in the launcher or in the panel. The free tier needs nothing else.
2. Start the game
Legacy or Enhanced, both work. The launcher detects which one is running. Start Enhanced without BattlEye.
3. Press Inject
The menu opens in game with F4 or Numpad *. Updates install themselves the next time you start the launcher.
What you need
Windows 10 or 11, 64-bit. Grand Theft Auto V, either build. No runtime to install first: the launcher is one self-contained file, and it downloads everything else it needs.
Current build
4.0.0 · 9.8 MB · released 18 September 2026
SYSLX V4 - Legacy + Enhanced. Detection in testing: stay in singleplayer with BattlEye disabled.
If your antivirus complains
The launcher writes a DLL and loads it into the game, which is the kind of behaviour antivirus heuristics flag. Every build we publish comes with a SHA-256 hash that the launcher checks before loading anything, and the hash for each release is shown in the panel. If a file does not match, the launcher deletes it instead of running it.
