Macro qui ne fonctione plus

Bonjour à vous j'ai du changer de pc car mon ancien pc ne fonctionnait plus trop avant j'avais office 2010 et maintenant office 2016 32 bits.

Et lorsque j'ai ouvert mon fichier excel joint, ma macro ne fonctionne plus.

C'est une macro qui me permet de pixeliser une image, je l'importe et lorsque je clique sur "Généré une fresque à partir...", la macro se lance mais elle colorise tout en blanc, alors qu'avant elle gênerait parfaitement l'image en pixel avec les couleurs qui correspondaient.

Lorsque je rentre dans les codes dans le module "GenerateField" je ne vois rien de bizarre, et je n'ai surtout rien changer entre mes 2 pc.

Private Declare Function GetPixel Lib "gdi32" (ByVal hDC As Long, ByVal x As Long, ByVal y As Long) As Long
Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long
Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long, lpRect As Rect) As Long
Private Declare Function GetCursorPos Lib "user32" (ByRef lpPoint As POINT) As Long
Private Declare Function CreateICA Lib "gdi32" (ByVal sDriver As String, _

Auriez vous une idée s'il vous plaît?
