GTA 4 .Net ScriptHook download

GTA 4 .Net ScriptHook download



GTA 4 .Net ScriptHook – This ASI plugin allows you to run ingame GTAIV scripts written in any .Net language. Those languages are easy to learn and use, while they are still extremely powerful.
One noteable aspect of this hook is, that the scripting functions are organized in a .Net-typical class structure, which makes finding functions intuitive and easy.
And since you are able to develop scripts with Visual Studio, you’ll get all benefits like code highlighting and IntelliSense.

You need an AsiLoader to use this plugin in GTAIV. See the Requirements section below for more info.


This software is provided ‘as-is’, without any explicit or implied warranty. The author(s) cannot be held accountable for any damage that might be caused by this software or any of it’s components.


Required to run this plugin are:

– A valid installation of GTA IV or EFLC patched to any of the following versions:
GTA IV: version up to version
EFLC: version up to version

Microsoft .Net Framework 4 and the Microsoft Visual C++ 2010 Redistributable Package (x86) installed on your machine
– Any AsiLoader installed for GTA IV

I included download links below. If the application crashes or behaves in an unwanted manner then download and install those updates/tools.

Microsoft .Net Framework 4 – DOWNLOAD
Microsoft Visual C++ 2010 Redistributable Package (x86) – DOWNLOAD (Make sure to install the linked x86 version, even on x64 systems!)


If you get a “MSVCR100.dll not found” error:
Try installing the Microsoft Visual C++ 2010 Redistributable Package! Make sure to install the linked x86 version, even on x64 systems!



Extract the complete archive into your GTAIV installation folder.


Extract the complete archive into your GTAIV installation folder.

Make sure that the ScriptHookDotNet.asi file is in your main GTAIV folder, or any other folder that is supported by your AsiLoader.
The ScriptHook.dll (which is aru’s C++ ScriptHook) should always be located in your main GTAIV folder, otherwise the .Net ScriptHook will be unable to find it! (thanks to Zach for pointing this out)
There may already be a ScriptHook.dll present. This is fine, because many mods use this file. In this case, check which one of the two files is newer and keep that.

Only the ScriptHookDotNet.asi and ScriptHook.dll files are required to run scripts.

All files in the “scripts\for Developers” subfolder are only required if you want to write own scripts. Look at the “Writing new scripts” section for more infos on this.

Script Installation

Scripts for the DotNet Script Hook have to be copied to the “scripts” subfolder of your GTAIV installation directory. You may have to create the folder if it is not there.

DotNet scripts may have one of the following file formats:
*.vb – for plain VisualBasic.Net scripts
*.cs – for plain C# scripts
*.net – for compiled scripts in any .Net language
*.net.dll – for compiled scripts in any .Net language

Writing new scripts

You should extract the “for Coders” folder from this archive to any folder you want. It contains example projects for you to start with. You could just edit the vb or cs script files with Notepad and copy the resulting script to the “scripts” subfolder of your GTAIV directory.

However, coding will be MUCH more comfortable and easy if you use Visual Studio 2010 to edit your scripts. Look below for a free download. Open the SLN Project files with Visual Studio to get ready-to-compile script examples. Use those examples as a base for your own scripts.
If you want to create a completely new VS project, make sure that you add a reference to the included ScriptHookDotNet.dll.
This file is ONLY required for coding. On runtime, your scripts will automatically use the ScriptHookDotNet.asi that is located in your GTAIV directory. Thus you don’t need to bundle your script with one of those files when you want to release it. If you don’t want to release the plain vb or cs script files, you can use the compiled DLL. You just have to make sure that the file ends to “.net.dll” or just “.net”!

If a script does not run, take a look at the logfile ScriptHookDotNet.log . It will write down all errors that occur during compiling or runtime.

Do NOT include ScriptHookDotNet.asi or ScriptHookDotNet.dll or ScriptHook.dll in the release of your script! Link to this thread instead!

Just delete the ScriptHookDotNet.asi from your GTAIV folder.

Scripts contained in the “scripts” subfolder can remain there if you wish to keep them. They wont run or interfere with the game when ScriptHookDotNet.asi is deleted.
