MTA:SA launcher code

MTA:SA error CL29

MTA says its own files do not look right at launch.

How to fix it

1. Install the current MTA release

   Close the game and run the current official MTA installer. A moderator advised updating in the December 2023 CL29 thread. Use today’s official download, not the old nightly build linked in that reply.

2. Start the copy you just updated

   Start MTA from the installation you just updated. If Windows has several MTA shortcuts, check where your shortcut points, so you do not open an older copy again.

3. Ask MTA support if CL29 comes back

   If CL29 comes back, stop reinstalling. Go to MTA Client support and give them the complete warning and the MTA build you have installed. No single fix is known to work for all current CL29 reports.

   Careful: “Possible virus activity” is only the wording of the warning. It does not confirm that your computer is infected.

These are the steps of the guide CL29: client integrity warning at launch.

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 CL29 as Legacy maybe-virus1 label.
