Special note for FitGirl 1.2.0.43 Repack downgrade
#GTA 4 PATCH 1.0.4.0 ROCKSFLY OFFLINE#
This method is for offline play only, if you need multiplayer you will have to replace XLivelessAddon with GFWL + Zolika's multiplayer addons/mods or GTAC. Remember that 1.0.4.0 does not support DLCs and if you need them you must also read the 1.0.7.0 section below and downgrade to 1.0.7.0 instead.
Once again - it is recommended to attempt the downgrade on a separate copy of GTA IV folder (the one that has GTAIV.exe), you may put this folder anywhere and rename it as you wish.
