MTA:SA launcher code

MTA:SA error CL13

The installation path contains characters MTA cannot work with.

How to fix it

  1. Look at every folder name in the GTA path

    Look at the full path of your GTA San Andreas folder. MTA needs every character in it to be standard ASCII: the English letters A to Z and a to z, the numbers 0 to 9, the space and common symbols. Letters with accents (like é) and letters from other alphabets (like Π or Σ) are not ASCII.

  2. Move GTA to a plain folder path

    Move your GTA San Andreas installation to a folder whose whole path has only standard ASCII characters. For example, MTA's manual gives C:\Program Files\Rockstar Games\GTA San Andreas\ as the default GTA folder.

  3. Reinstall MTA and choose the new folder

    The message says to reinstall Multi Theft Auto after the move. When the installer asks for the folder where San Andreas is installed, choose the new folder.

These are the steps of the guide CL13: GTA path contains unsupported (unicode) characters.

Still not fixed? Copy the whole message, not only the code, and check your log in the Fix tool. It is read on your own computer.

About this code

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 CL13 as Unsupported path characters.
