Launcher settings

Open Launcher from the sidebar. Save changes with Save (or enable batch save in Settings → General).

Behavior

Setting	What it does
Multi-instance	Allow more than one Roblox client at a time.
Launch confirmation	Prompt before starting a session.
Auto-update Roblox	Keep the managed Roblox build current for your channel.
Silent launch	Reduce UI noise during startup (when supported).
Headless mode	Launch without showing certain UI steps (advanced).
Launch timeout	How long to wait for the client to start before failing.

Setting	What it does
Channel	Roblox update channel (`live`, `zlive`, `znext`, `zcanary`, …). Changing channel may trigger a new download.
Install location	Where Carbon stores the Roblox version folder it patches.
Force reinstall	Re-download the client for the selected channel.
Background updates	Download Roblox updates while idle.

Mods always patch files under this install location. If mods “do nothing,” confirm the channel finished updating and launch again.

Scheduled or manual cleanup can remove old downloads, Roblox logs, and Carbon logs. Use this when disk usage grows after many channel switches.

Launcher → Logs opens the launch log viewer. Pair with files in logs/ on disk when reporting issues. See Troubleshooting.
