(Sorry my English is not good)

I've made a small game with UDK(Unreal Development Kit)Latest Release(December 2011 UDK Beta) and used frontend for package my game; When I install the game on the user's computer(user os is winxp sp3 32bit or windows 7 sp1 32bit without .net framework) Installer program can follow the steps below:

  1. install .net framework 4 full
  2. run UE3Redist.exe (this program install DirectX & Microsoft Visual C++ 2010 Redistributable Package (x86-x64))
  3. copy require files

(I tried not installing the .net framework 4; I gives 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 .net framework is require?
  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)

more or less dupe of gamedev.stackexchange.com/questions/21496/… –  Jari Komppa Jan 4 '12 at 13:42
But I did not notice. .net framework 4 is required or not.(please help me) –  shahab Jan 5 '12 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. –  michael.bartnett Jan 5 '12 at 10:38

I made a game with UDK, and after packed with FrontEnd and installed on other computer, it required things that you have mentioned. I installed all of the things needed and afterwords uninstalled .net 4, and my game worked just fine. I presume that .net is required for some system tasks within your game, like saving/loading game data such as checkpoint, scores and similar, which I didn't have in my game. This, of course my not be the case, I will inspect more, but since my game worked, I believe that .net is something that only UDK installer requires. Will try to pack with some other installers and see what happens.

Also, I made two games with UNITY, and it didn't require any external packages.
