If you’re stepping into GTA V modding or building custom interfaces for ScriptHookVDotNet projects, you’ve likely come across LemonUI. It’s a modern and lightweight UI framework used by developers to create clean, interactive in-game menus and interfaces without dealing with overly complex UI systems.But before you start building sleek menus, you need to understand something important: the system requirements for using LemonUI.
Even though LemonUI itself is not a heavy standalone application, it depends on several tools, frameworks, and system capabilities. In this guide, we’ll break everything down in a simple, human-friendly way so you know exactly what you need before getting started.

Understanding LemonUI First
Before jumping into system requirements, it helps to understand what LemonUI actually is.
LemonUI is a UI library primarily used in GTA V modding, especially with:
- ScriptHookVDotNet
- C# mod development
- Custom in-game menus and HUD elements
It is a replacement for older UI frameworks like NativeUI and is designed to be more flexible, modern, and easier to maintain.
Since LemonUI runs inside GTA V through ScriptHookVDotNet, its requirements are not standalone—they depend heavily on your game and development environment.
Minimum System Requirements for LemonUI
Let’s start with the basic system requirements you need to run LemonUI smoothly.
Operating System
LemonUI itself is platform-independent in theory, but in practice, it is used for GTA V modding on Windows.
Minimum Requirement:
- Windows 10 (64-bit)
- Windows 11 (64-bit)
Why it matters:
GTA V modding tools like ScriptHookVDotNet only support Windows. So even though LemonUI is just a library, you must be on a compatible Windows system.
GTA V Installed (Legal Copy Required)
Since LemonUI is used inside GTA V, you must have the game installed.
Requirements:
- GTA V (latest updated version recommended)
- Steam / Epic Games / Rockstar Launcher version
Important Note:
Always use a legitimate copy of GTA V. Modding pirated versions can lead to errors, crashes, or missing dependencies.
ScriptHookV
LemonUI does NOT run alone—it depends on ScriptHookV.
Required:
- Latest version of ScriptHookV installed in GTA V directory
ScriptHookV allows native functions and scripts to run inside GTA V, making it essential for any mod that uses LemonUI.
ScriptHookVDotNet
This is one of the most important dependencies.
Minimum Requirement:
- ScriptHookVDotNet 3.x (recommended latest stable version)
Why it’s required:
LemonUI is built for .NET scripting. ScriptHookVDotNet enables C# scripts to run inside GTA V.
Without it, LemonUI will simply not work.
Microsoft .NET Framework / .NET Runtime
Since LemonUI is a C# library, it requires the correct .NET environment.
Required Versions:
- .NET Framework 4.8 (commonly used in GTA V modding)
- OR compatible .NET runtime supported by ScriptHookVDotNet
Why it matters:
If your .NET version is outdated, you may experience:
- Script crashes
- UI not loading
- Game freezing during script execution
Visual Studio (For Developers)
If you are not just using mods but actually developing with LemonUI, you will need a proper IDE.
Recommended:
- Visual Studio 2019 or later
- Visual Studio 2022 (best option)
Required components:
- .NET desktop development workload
- C# support
This is where you write and compile scripts that use LemonUI.
Minimum PC Hardware Requirements
LemonUI itself is lightweight, but GTA V is not. So your system must meet GTA V requirements at minimum.
Minimum Hardware:
- CPU: Intel Core i5 (2nd generation or newer)
- RAM: 8 GB
- GPU: NVIDIA GTX 660 / AMD HD 7870 (or better)
- Storage: At least 120 GB free space
- DirectX: Version 11
Recommended Hardware:
- CPU: Intel i5 / i7 (6th gen or newer)
- RAM: 16 GB
- GPU: GTX 1060 or higher
- SSD storage for faster loading
File Placement Requirements
LemonUI works through script injection, so correct file placement is critical.
Typical setup requires:
- Scripts folder inside GTA V directory
- LemonUI.dll placed in:
GTA V / scripts / Also required:
- Your compiled mod (.dll file) also goes into the scripts folder
Incorrect placement is one of the most common reasons LemonUI doesn’t work.
Supported Development Language
LemonUI is designed for:
- C# (primary language)
- .NET-based scripting
You must know:
- Basic C# programming
- Object-oriented programming concepts
- Event-driven UI logic
Without C# knowledge, using LemonUI effectively becomes very difficult.
GTA V Game Settings Compatibility
While not a strict system requirement, game settings affect performance.
Recommended settings:
- Windowed Borderless mode (for debugging)
- DirectX 11 enabled
- Updated graphics drivers
- Mods enabled properly via ScriptHookV
Optional but Recommended Tools
These are not required but highly useful for smooth development.
OpenIV
Used for managing game files and mods safely.
CodeWalk / Debug Tools
Helps track script errors.
Git (Version Control)
Useful for managing LemonUI-based projects.

Forums and GitHub repositories for LemonUI examples.
Why System Requirements Matter for LemonUI
Even though LemonUI is “just a UI library,” ignoring requirements can lead to:
- Game crashes
- UI not loading
- Script errors
- Missing dependencies
- Poor performance
Most issues beginners face are not because of LemonUI itself—but because one of its dependencies is missing or outdated.
Common Problems Due to Incorrect Setup
Here are some common errors users face:
LemonUI Not Showing In-Game
Usually caused by:
- Missing ScriptHookVDotNet
- Incorrect file path
Game Crashes on Startup
Possible reasons:
- Outdated ScriptHookV
- Wrong .NET version
Scripts Not Loading
- DLL not placed in scripts folder
- Security permissions blocking execution
Conclusion
LemonUI is a powerful and modern UI framework for GTA V mod development, but it doesn’t work in isolation. To use it effectively, you need a properly configured environment that includes GTA V, ScriptHookV, ScriptHookVDotNet, and the correct .NET Framework version.
While the library itself is lightweight, most issues come from missing or outdated dependencies rather than LemonUI itself. That’s why setting up your system correctly is the most important step before you start building custom menus or interfaces.
