The number 1.0.350.1 refers to a specific build of Grand Theft Auto V itself, not necessarily the version of Script Hook V. This build corresponds to a patch released in early 2015—specifically the "Ill-Gotten Gains" update era.
Why are people searching for this today? There are two primary reasons:
Important Note: Alexander Blade does not release a separate "Script Hook V version 1.0.350.1." Instead, he releases a universal updater. However, older archives of Script Hook V from 2015 are compatible with game build 1.0.350.1. This article guides you on acquiring the correct legacy file.
Cause: The files are in the wrong directory, or Windows Defender has quarantined them.
Fix:
Script Hook V is a library that allows you to run custom .asi plugin scripts in Grand Theft Auto V. It is the fundamental tool required for most advanced modding, including popular mods like "Native Trainer," vehicle mods, and gameplay overhauls.
The Issue: You might have outdated .asi mods that are incompatible with the 1.0.350.1 game logic.
The Fix: Temporarily move all other .asi files (except ScriptHookV.dll and NativeTrainer.asi) to a backup folder on your desktop. Add them back one by one to find the culprit.
