A problem-solving guide for SAMPCAC (Client-side Anti-cheat for SA-MP)

Warning

SAMPCAC requires SA-MP Client version 0.3.7 R1

The most common problems and their solutions:

  • SAMPCAC installer gives Windows version mismatch error

Download sampcac_client.asi separately, or run the installer in Windows XP compatibility mode (Service pack 3).

  • After connecting not reaching the skin selection, crash with format codes 0x06XXXXXXX where X are arbitrary characters

Reinstall the SA-MP client through the original installer (not by changing the files)

  • Error when clicking "Connect" button in SA-MP client. 0x0040fB80 or similar.

Install sa-mp 0.3.7 client again and change version of GTA_SA.exe to US 1.0

  • Black screen.

Delete the gta_sa.set file from the GTA San Andreas User Files folder

  • 0x0059F8B4

Crash occurs when the client cannot load any object on the server from samp.img. Reinstall the client and try running SA:MP as an administrator.

  • The game does not start on Windows10 / Windows11 (no crash)

On a Windows 10 system, the old DirectPlay must be enabled. To do this, go to "Control Panel » Programs » Uninstall Programs » Turn Windows features on or off" and check "Legacy Components and DirectPlay".

  • SA-MP Clientside Anticheat cannot run under a Virtual Machine.
