The only one solution is to download the source code of the engine and compile it then run your project on it… you can download 4.4 or get all releases from this link
https://github.com/EpicGames/UnrealEngine/releases
This is tutorial for how to compile the engine using Visual Studio 2013
Hope that will help
Edit: Don’t forget to download Required_1of2.zip and Required_2of2.zip and unzip them in cloned source folder. In order you have to unzip 1of2 first then 2of2 then the source of the engine.
