OIV Package Installer

OIV Package Installer is a lightweight alternative to the OpenIV Package Installer. Built on the CodeWalker core, it offers a clean, reliable interface for installing OIV modification packages for Grand Theft Auto V Legacy and Enhanced.

Source Code: https://github.com/crxhvrd/CodeWalkerProjects

Features:
- Full Compatibility: Works with all existing OIV mods and packages.
- Uninstall mods via Manage Mods: Safely remove installed mods using the built-in manager.
- Clean Interface: A familiar UI inspired by OpenIV, providing a clear summary of package metadata.
- Game Support: Fully supports both GTA V Legacy and GTA V Enhanced versions.
- Smart Validation: Automatically validates your game version against the mod's requirements to prevent compatibility issues.
- Safe & Secure: Properly handles file placement logic, ensuring DLC packs and RPF modifications are correctly installed to your mods folder.

Requirements:
To ensure your mods folder works correctly, you must have the appropriate mods loader installed:
- GTA V Legacy: Requires OpenIV.asi
- GTA V Enhanced: Requires OpenRPF.asi

Important Note:
Please ensure the mod you are installing is compatible with your game version. Legacy mods cannot be installed on GTA V Enhanced, and Enhanced mods cannot be installed on GTA V Legacy. Installing incompatible mods will cause your game to crash.

How to Use:
1. Launch CodeWalker.OIVInstaller.exe.
2. Select your .oiv package file.
3. Select your GTA V game folder.
4. Click Install and wait for the process to complete.
5. Use the Manage Mods tab to uninstall mods if needed.

For Mod Creators:
The installer validates the <gameversion> tag in assembly.xml to ensure your mod is installed on the correct game version.

To enforce game version validation, add the <gameversion> tag to your assembly.xml file inside the <package> element.

Example for Enhanced Edition:
<gameversion>enhanced</gameversion>

Example for Legacy Edition:
<gameversion>legacy</gameversion>
