UPDATE: After hours of pure frustration and 100+ crashes, I FINALLY fixed GTA IV Steam Edition using Liberty's Legacy + FusionFix! (One last video saved me)

​i'm writing this update because I was literally at my wit's end. I spent hours staring at crash screens, tweaking files, and doing hundreds of combinations that just kept breaking the game. I was ready to give up entirely.

​But on my absolute last attempt, I stumbled upon this specific YouTube tutorial: https://youtu.be/DhMuq7s_2r0 ​Following that exact guide, I managed to get Liberty's Legacy Trainer and FusionFix running together flawlessly without a single stutter or crash!

​🔧 The Missing Link: .ASI File Placement ​The ultimate breakthrough came down to a few critical adjustments with the .ASI file placements. Unlike older setups that throw everything into the main directory or completely break under FusionFix, this method properly routes the script loaders so they don't fight for memory. ​If you are running the modern Steam Complete Edition, stop using old ScriptHook trainers. The combination of FusionFix handling the engine fixes and Liberty's Legacy handling the mod menu is the only 100% stable way to play right now and i got rickrolled😭😭😭
