Horizon Forbidden West Complete Edition 1.5.80.0 Patch Notes

3.1 Content Expansion

The primary driver of the version jump to 1.5.80 was the integration of the "Burning Shores" DLC. This expansion transported protagonist Aloy to a volcanic, post-apocalyptic Los Angeles. Technically, this required the executable to support: New asset streaming for high-density urban geometry

Part 7: Why You Should Update Today (Even If You’re Stable on 1.0.37)

Some players adopt a “if it ain’t broke, don’t fix it” mentality. Here’s why that’s misguided for Horizon Forbidden West:

1. The Burning Shores DLC requires 1.5.xx or higher. You can’t even launch the expansion on 1.0.37.
2. Cross-save compatibility. Cloud saves from newer patches may not load on old executables.
3. Exploit patches. Version 1.0.37 has a known buffer overflow in the photo mode that can be used by malicious save files (rare, but real).
4. Windows 24H2 compatibility. Future Windows updates (due Oct 2024) will break 1.0.37’s DirectStorage implementation. 1.5.80 includes forward-compatible stubs.

4. Technical Analysis of the Executable

The file naming convention "update 1.0.37 - 1.5.80.exe" implies a cumulative patch often found in offline installers or third-party distribution channels (such as fan archives or backup repositories).

• Cumulative vs. Incremental: In digital storefronts like Steam, updates are applied incrementally (delta patching). However, an executable labeled with a version range suggests a standalone installer that brings a fresh installation from the launch state directly to the current state.
• Security Implications: While official updates are delivered via encrypted launcher protocols, standalone .exe patch files serve a vital purpose for preservation and offline gaming. However, users must verify the cryptographic signature of such files to ensure they have not been tampered with or injected with malware, as executable files are primary vectors for security threats.

4. Mod Compatibility Hooks

Silently, the later exe files added more robust .DAT file loading. Modders on NexusMods have noted that the 1.5.80 exe no longer crashes when loading custom armors or reshade presets.

Part 1: The State of Play – What Was Version 1.0.37?

Upon release, Horizon Forbidden West version 1.0.37 was the “day-one” build for PC. It was far from broken—unlike some high-profile releases that year—but it had growing pains.

Step-by-Step Installation Guide

If you possess a legitimate copy of the game (Steam or Epic Games Store), these updates happen automatically. However, offline installers and specific DRM-free versions (like GOG) may require manual execution of the Horizon Forbidden West update 1.0.37 - 1.5.80.exe file.

Prerequisites:

• Ensure your base game is exactly version 1.0.37 (Check: Right-click HorizonForbiddenWest.exe > Properties > Details).
• Have at least 35GB of free space (The patcher needs temp space for file reconstruction).
• Disable your antivirus temporarily (some patchers modify .exe signatures, triggering false positives).

Installation Steps:

1. Backup your saves: Navigate to Documents\Horizon Forbidden West\Saved Game Games. Copy this folder to your desktop.
2. Run as Administrator: Right-click the .exe file and select "Run as Administrator".
3. Select Game Root: Browse to where HorizonForbiddenWest.exe lives (e.g., C:\Program Files (x86)\Steam\steamapps\common\Horizon Forbidden West).
4. Verify Checksum: The patcher will take 3-5 minutes to verify the existing 1.0.37 files. If any base files are modified (modded), the patcher will fail.
5. Apply Patch: Click "Start". This process takes approximately 15 minutes on an NVMe SSD, or 45 minutes on a hard drive.
6. Success: You will see "Update completed successfully. New version: 1.5.80."
