GTA IV Patch 1.0.4.0 Download: The Ultimate Guide to the Best Version for Mods

Steam previously offered a “patch-1.0.4.0” beta branch, but it was removed in 2020. No longer available.

1. Install Base Game: Install GTA IV via Steam. Let it update to the latest version (currently 1.0.8.0 or 1.0.7.0).
2. Backup your install: Copy the Grand Theft Auto IV folder to your desktop. (Always backup).
3. Download the Downgrader: Search for GTA IV Downgrader by Zolika1351 (v 2.0 or higher). This is hosted on GitHub or dedicated GTA modding forums.
4. Run the Tool: Select version 1.0.4.0 from the dropdown. The tool will automatically download the necessary 1.0.4.0 executable and scripts from Rockstar’s old CDNs (Content Delivery Networks) – which is legal because you own the license.
5. Install Dependencies: The tool will install DirectX 9, Visual C++ Redistributables, and XLiveLess (to kill GFWL).

The Legal Way:

You must own a legitimate copy of GTA IV. Here is how most users do it:
