I need a patch for gta san andreas because near the end of the installation a window pops up saying "CRC error:the file C:/program files/Rockstar games/gta san andreas/audio/streams/AA does not match the file in the setups .cab file.the median from which you are running the setup may be corrupted; please contact your vendor".

can someone help me?

Have you installed any mods for the game? If you are having problems updating the game using their patch, I would contact their support department.

If you have any mods installed that have replaced any files that the game contained origionally, then it will cause these errors. (Such as Coffee Mod) for example.
