I have done as you have said here, I have glfw3.dll into the same 
directory as the executable, and included the dependencies in the 
dub.json file, however when I run my intialization code, it gives 
me the following error:

derelict.util.exception.SharedLibLoadException at src\derelict-util\source\derelict\util\exception.d(35): Failed to load one or more shared libraries:
	glfw3.dll - Access is denied.

The code I have that runs derelictGLFW3.load() etc is as follows:

import derelict.opengl3.gl3;
import derelict.glfw3.glfw3;

int main()
{
	DerelictGL3.load();
	DerelictGLFW3.load();
	
	GLFWwindow* window;
	
	if(!glfwInit())
	{
		return -1;
	}
	
	window = glfwCreateWindow(1280,720, "D OpenGL Engine", null, 
null);
	if(!window)
	{
		glfwTerminate();
		return -1;
	}
	
	/* make window' context current */
	glfwMakeContextCurrent(window);
	DerelictGL3.reload();
	
	while(!glfwWindowShouldClose(window))
	{
		glfwSwapBuffers(window);
		glfwPollEvents();
	}
	
	glfwTerminate();
	return 0;
}
