In Delphi/Borland C++ (common for old ASIs), range checks are enabled with $R+. An ERangeError means code tried to access an array/set index outside declared bounds. At offset 00007e9c, the mod likely reads or writes to a game memory array that has a different size than expected — usually due to:
| Cause | Description |
|-------|-------------|
| Game version mismatch | gfxhack expects the game executable to have specific memory patterns; v2.0 or Steam versions may differ. |
| Conflicting mods | Another .asi (e.g., d3d9.dll, SilentPatch, FPS Limiter) alters the same rendering functions. |
| Outdated gfxhack | Old versions don’t support modern GPUs or Windows 10/11 D3D9 wrapper behavior. |
| Corrupted installation | Missing or damaged gfxhack.ini, d3d9.dll, or game files. |
| DEP / ASLR conflicts | Windows Data Execution Prevention may block the ASI’s code injection. |
To fix this error, you must first understand its components.
ERangeError is rare in modern C++ mods (which use std::out_of_range). Its appearance suggests the mod was originally compiled with Borland Delphi or C++ Builder and fails when a calculation (e.g., ScreenWidth * ScreenHeight exceeds High(Integer)).
If you’re a mod developer, wrapping suspect calls with try..except in Delphi or switching to safe integer math could prevent this.
"Exception ERangeError in module GFXHack.asi at 00007E9C" is a technical crash that typically affects players of Grand Theft Auto: San Andreas (GTA SA) Exception Erangeerror In Module Gfxhack.asi At 00007e9c

. Its primary purpose is to fix graphical issues or enable advanced visual features, often bundled with high-quality vehicle mods like Improved Vehicle Features (ImVehFt) Active Dashboard Why the Error Happens Version Incompatibility:
The mod might not be compatible with your specific version of GTA San Andreas (e.g., v1.0 vs. Steam version) or your Windows operating system Missing Dependencies: The plugin often requires an ASI Loader Silent's ASI Loader ) to function correctly Conflicting Mods:
If multiple mods try to modify the same graphical files simultaneously, it can trigger a range check failure Common Fixes Install/Update ASI Loader:
Ensure you have the latest version of an ASI Loader (vorbisFile.dll and vorbisHook.dll) placed in your main game directory Compatibility Settings: Right-click your gta_sa.exe Properties > Compatibility , and set it to run in Compatibility Mode for Windows 7 Windows XP (Service Pack 3) , and always Run as Administrator Check Mod Files:
Some users find that the error is caused by a specific vehicle mod that requires a newer version of the GFXHack plugin or its associated scripts Verify Game Integrity: If you are on Steam, use the Verify Integrity of Game Files tool to ensure the base game files aren't corrupted Are you using a specific vehicle mod when this crash happens?

Corruption is the easiest fix.
| Cause | Explanation |
|-------|-------------|
| Game version mismatch | GfxHack expects a specific game executable (e.g., GTA SA 1.0 US HOODLUM), but you have a different version (Steam, 1.01, or downgraded incorrectly). |
| Incompatible mod combination | Conflicts with other .asi mods (SilentPatch, SkyGFX, ModLoader) that hook the same graphics functions. |
| Corrupted or partial installation | Missing dependencies (like d3d9.dll wrappers) or incorrect folder structure. |
| Outdated GfxHack version | Newer OS (Windows 10/11) or GPU drivers may break older ASI mods expecting DirectX 9.0c behaviors. |
| Memory or pointer issue | The mod tries to access a render target, texture, or vertex buffer that hasn't been initialized. |
