What it means

CL codes come from MTA's launcher, before the game starts: installing an update, finding GTA, loading MTA's own files or starting gta_sa.exe. MTA's own documentation gives this code as Duplicate-instance termination prompt.

How to fix it

Work down the list and stop when it is solved.

Longer version, with a source on every step: Another MTA or GTA instance is already running.

  1. Let it close the other copy

    Accept the prompt, or close the other MTA yourself, then start again.

  2. Copy the whole message first

    Write down every line MTA shows, not only the code. The rest of the message often names the file, the server or the reason, and that is what tells you which step below applies.

  3. Repair your MTA installation

    Run the current installer from multitheftauto.com over your existing installation. It replaces MTA's own files without touching your settings.

Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
