How to Mod GTA IV
Step by Step instructions to Mod GTA IV with iCEnhance Mod, install Texture Packs, Fonts Mod, and tweak different graphics variables.
Install a fresh copy of the Grand Theft Auto 4 into your hardisk. iCEnhance Mod only works with the older version of the game – till patch 220.127.116.11. If you are running the latest patch then you need to uninstall the game and do a fresh installation and update it till patch version 18.104.22.168.
Make a backup of the existing game for when something goes wrong. You can download the patch 22.214.171.124 from here. You should choose the ‘Do not update automatically’ if you are running a steam version of the game from Updates tab.
Now you need to install the Rockstar Social Group Tool (RSGT) by downloading it from here. Before you install RSGT, rename GTA IV folder to some different name. RSGT will create a new GTA4 folder. Copy all the files inside RSGT created folder to the original GTA IV folder that you renamed. Once you have copied everything back to the renamed folder from RSGT created folder, delete RSGT created GTA IV folder and rename the GTA IV folder back to original name.
Now look for the LaunchGTAIV.exe file in the GTA IV folder and create a shortcut on the desktop. Rightclick on the shortcut and select properties, now find the target field and add “norestrictions” without the quotation marks at the end of the text. This will remove the graphic restrictions in the game allowing you to custom change the graphic settings in the game.
Now comes the good stuff, download the iCEnhancer mod from here. Extract the files from this folder and copy them into the Normal version for 1040 patch folder. Overwrite the existing files if asked. Copy the xlive.dll and xlive_d.dll files into your GTA IV folder. Download the fonts mod from here and copy its content into the data folder inside GTAIV\common and overwrite the existing files. It will allow the fonts in the menu to appear correctly.
