If deleting the file causes the game to launch but the graphics look strange (e.g., the HUD is stretched, or resolutions are missing), you might actually need that file—but a different version of it.
A faulty ASI loader can misinterpret memory addresses, triggering "RangeError." Exception Erangeerror In Module Gfxhack.asi At 00007e9c
Before we fix it, it helps to know what file is causing the trouble. If deleting the file causes the game to
The file gfxhack.asi is not a standard part of the vanilla GTA San Andreas installation. It is a script file typically associated with graphic modification patches or multiplayer mod loaders. Specifically, it is often linked to older versions of the SA-MP (San Andreas Multiplayer) client or certain widescreen fixes intended to improve the game's resolution handling. It is a script file typically associated with
Essentially, this file tries to "hook" into the game's memory to inject new code. The error is telling you that the file is trying to access a memory address that doesn't exist or is out of bounds.
Before fixing the issue, identify which of these scenarios matches your setup:
| Cause | Likelihood | Description |
| :--- | :--- | :--- |
| Invalid Resolution | High | The mod is set to a resolution (e.g., 1920x1080) that conflicts with the game’s internal resolution lock or Windows scaling settings. |
| Corrupted ASI File | Medium | The gfxhack.asi file itself is partially downloaded, outdated, or patched incorrectly. |
| DirectX/GPU Conflict | Medium | You are using a modern graphics card (NVIDIA RTX 30/40 series or AMD RX 6000/7000 series) with an incompatible version of gfxhack. |
| Mod Conflict | High | Another .asi mod (e.g., d3d9.dll, modloader.asi, or SilentPatch) is trying to hook the same DirectX functions as gfxhack. |
| Windows Compatibility | Low | Windows 10/11’s fullscreen optimizations or high-DPI scaling is interfering with the mod’s memory range calculations. |
