This guide will walk you through downgrading any legitimate copy of GTA IV to 1.0.7.0, whether you own the old DVD, Steam version, or the Rockstar Launcher "Complete Edition."
Drop .asi files into the main directory. The downgrader's built-in ASI loader will execute them automatically.
You can bypass the mandatory background launcher, reducing CPU overhead and system friction. Prerequisites Before You Begin
Old DVD copies have SecuROM DRM that crashes on Windows 10/11. You need a no-CD crack specifically for 1.0.7.0 . (Note: Use this only if you own the legal DVD). Place the cracked GTAIV.exe and LaunchGTAIV.exe in the root folder.
Even with a perfect install, issues can arise. Here are solutions to common problems.
The Complete Edition is only better if you:
Modern graphics enhancers (ENB presets) require the rendering engine of patch 1.0.7.0. The Complete Edition breaks ENB shaders entirely.
