# UDK requirements

I've made a small game with UDK (Unreal Development Kit, release of December 2011 UDK Beta) and used frontend to package my game;

When I install the game on the user's computer (the OS of the user is Windows XP SP3 32 bit or Windows 7 SP1 32 bit without .NET Framework), the installer program follows the steps below:

1. install .NET Framework 4 (full installation)
2. run UE3Redist.exe (this program installs DirectX & Microsoft Visual C++ 2010 Redistributable Package for x86 and x64)
3. copy the required files

I tried to not install the .NET Framework 4 but it gives this error:

*
--------------------------
TestGame.exe - .NET Framework Initialization Error
---------------------------
To run this application, you first must install one of the following versions of
the .NET Framework: v4.0.30319 Contact your application publisher for instructions
about obtaining the appropriate version of the .NET Framework.
*

1. Why is the .NET Framework required?
2. If I want to build my custom setup for my game, do I need to install the .NET Framework 4? (I read UDK System Requirements.)

• But I did not notice. .net framework 4 is required or not.(please help me) Jan 5, 2012 at 6:27
• Please ask on the UDK forums, you're more likely to get a relevant answer there. This is more of a tools troubleshooting question that I'm not sure is useful or feasibly answered here. As for #1, it's probably because the editor uses WPF or Forms or other .Net components. Jan 5, 2012 at 10:38
