CreateDevice failed in DX9 under Vista [SOLVED]

Hello, I am currently working on a DX9 game engine. I started the development under XP but I changed to Vista recently. Under Vista, call to ::createDevice always fails returning D3DERR_INVALIDCALL (the same piece of code works fine under XP, I tried it on at least 3 or 4 computers). Here is the D3D initialization code :



HRESULT InitD3D (int resWidth, int resHeight, D3DFORMAT resFormat, HWND hWnd, DWORD fullScreen)
{
HRESULT hr;
D3DDISPLAYMODE d3ddm;


//---------------------------------------------
//         Create D3D object
//---------------------------------------------
d3d = Direct3DCreate9(D3D_SDK_VERSION);

// Make sure NULL pointer was not returned
if (!d3d)
  return FALSE;

//---------------------------------------------
//       Get device capabilities
//---------------------------------------------
ZeroMemory (&d3dCaps, sizeof(d3dCaps));
    
D_CHK ( d3d->GetDeviceCaps (D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, &d3dCaps) );

//---------------------------------------------
//     Setup device present parameters
//---------------------------------------------
ZeroMemory(&d3dPresent,sizeof(d3dPresent));

// WINDOWED MODE
if (fullScreen == 0)
{
        
  RECT rWindow;

  // Get display mode
  D_CHK ( d3d->GetAdapterDisplayMode (D3DADAPTER_DEFAULT, &d3ddm) );

  // Get window bounds
  GetClientRect (hWnd, &rWindow);

  // Setup backbuffer format
  d3dPresent.Windowed = true;
  d3dPresent.BackBufferFormat	= d3ddm.Format;
  d3dPresent.BackBufferWidth	= rWindow.right - rWindow.left;
  d3dPresent.BackBufferHeight	= rWindow.bottom - rWindow.top;	
}
// FULLSCREEN MODE
else
{      
  // Setup backbuffer format
  d3dPresent.Windowed = false;
  d3dPresent.BackBufferFormat = resFormat;
  d3dPresent.BackBufferWidth  = resWidth;
  d3dPresent.BackBufferHeight = resHeight;	
}

// Front / Back buffer
d3dPresent.SwapEffect		= D3DSWAPEFFECT_DISCARD; 
d3dPresent.hDeviceWindow	= hWnd;
d3dPresent.BackBufferCount	= 1;
d3dPresent.PresentationInterval	= D3DPRESENT_INTERVAL_DEFAULT;

d3dPresent.MultiSampleType	= D3DMULTISAMPLE_NONE; // No multisample
d3dPresent.MultiSampleQuality	= 0;

// Stencil buffer
d3dPresent.EnableAutoDepthStencil = TRUE;
d3dPresent.AutoDepthStencilFormat = D3DFMT_D16;

D_CHK (d3d->CheckDeviceFormat(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL,
	d3ddm.Format, D3DUSAGE_DEPTHSTENCIL, D3DRTYPE_SURFACE,
        d3dPresent.AutoDepthStencilFormat));

D_CHK (d3d->CheckDepthStencilMatch(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL,
       d3ddm.Format, d3dPresent.BackBufferFormat, 
       d3dPresent.AutoDepthStencilFormat));

// Others
d3dPresent.Flags			= 0;
d3dPresent.FullScreen_RefreshRateInHz	= 0;

//---------------------------------------------
//			 Create D3D device 
//---------------------------------------------
if (d3dCaps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT)
{    
  // Create device with hardware vertex processing
  D_CHK ( d3d->CreateDevice(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL, hWnd,
                D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dPresent, &d3dDevice) );
}
else
{
  // Create device with software vertex processing
  D_CHK ( d3d->CreateDevice(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL, hWnd,
            D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dPresent, &d3dDevice));
}
				
//---------------------------------------------
//	 Enable dialog boxes (Windows mode only)
//---------------------------------------------
if (fullScreen==0) {
  D_CHK ( d3dDevice->SetDialogBoxMode(TRUE) );
}

return TRUE;
}

D_CHK is a simple macro to check HRESULT value and exit when it fails. My development environment : - Visual Studio C++ .NET 2003. - Microsoft DirectX SDK (June 2008) - Vista Family Premium SP1 - Video Card : ATI Mobility Radeon HD 3470 I include , and I link with d3d9.lib d3dx9.lib dxerr.lib I know that Vista includes both DX9 and DX10. Do I need to indicate to Vista I want to execute the application under DX9 ? (somewhere in the tool settings or the project configuration) If not, does anybody have an idea to explain why createDevice fails ? Thank you in advance for your answer.
