Device works with setup.exe but doesnot with sdk

[devinevector]

The device works fine with the setup program but when i use program nothing detected.
The sdk 2.3.1 program doesn't show error on compiling, it's on X64 so i merely put .net4.0, Leap and LeapCSharp into the folder.
What could cause this happen?

It sounds like you're using the V2 SDK with an Orion example. The Orion example relies on the LeapC API, which didn't exist in V2.

No, the example i just write myself. The listener file looks below:
using System;
using System.Windows.Forms;
using Leap;

namespace WindowsFormsApplication1
{
class LeapListener: Listener
{
public override void OnInit(Controller cntrlr)
{
}

    public override void OnConnect(Controller cntrlr)
    {
        currentTime = currentFrame.Timestamp;
    }

    public override void OnDisconnect(Controller cntrlr)
    {
    }

    public override void OnExit(Controller cntrlr)
    {
    }

    private long currentTime;
    private long previousTime;
    private long timeChange;
    private int ct;
    private Frame currentFrame;

    public override void OnFrame(Controller cntrlr)
    {
        // Get the current frame.
        currentFrame = cntrlr.Frame();

        currentTime = currentFrame.Timestamp;
        timeChange = currentTime - previousTime;

        if (timeChange > 10000)
        {
            if (!currentFrame.Hands.IsEmpty)
            {
                for (ct = 0; ct < currentFrame.Gestures().Count; )
                {
                    switch (currentFrame.Gestures()[ct].Type)
                    {
                        case Gesture.GestureType.TYPE_SWIPE:
                            break;
                        case Gesture.GestureType.TYPEKEYTAP:
                            // Get the first finger in the list of fingers
                            Finger finger = currentFrame.Fingers[0];
                            // Get the closest screen intercepting a ray projecting from the finger
                            //Leap.Screen screen = cntrlr.LocatedScreens.ClosestScreenHit(finger);
                            // Get the velocity of the finger tip
                            var tipVelocity = (int)finger.TipVelocity.Magnitude;

                            // Use tipVelocity to reduce jitters when attempting to hold
                            // the cursor steady
                            if (tipVelocity > 5)
                            {
                                // keypress
                                SendKeys.Send("{W}");
                            }
                            break;
                        default:
                            break;
                    }
                }

                previousTime = currentTime;
            }
        }
    }
}

}

This is the main program:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Leap;
using WindowsHookLib;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

    KeyboardHook hk=new KeyboardHook();
    Controller cntrl = new Controller();
    Listener listener = new Listener();

    private void Form1_Load(object sender, EventArgs e)
    {
        // Put your own handler here
        hk.InstallHook();
        cntrl.AddListener(listener);
        cntrl.EnableGesture(Gesture.GestureType.TYPEKEYTAP);
        cntrl.EnableGesture(Gesture.GestureType.TYPESWIPE);
    }

    private void Form1_Unload(object sender, EventArgs e)
    {
        cntrl.Dispose();
        hk.RemoveHook(); }
}

}
