In the world of GTA IV modding, "12059" refers to the version number of a specific game executable or DLL file—most commonly GTAIV.exe or GFSDK_ShadowLib.win32.dll—that is associated with Patch 8 (1.0.8.0) or Patch 7 (1.0.7.0). However, the number is frequently cited in Social Club error messages that read: "Rockstar Games Social Club failed to load due to an incomplete installation (code 12059)."

For Xbox Series X|S players, this was a game-changer, utilizing the "FPS Boost" feature to finally run the game at a stable 30-60 FPS—something the Xbox 360 struggled with heavily in Algonquin.
