Thanks for your answers (it was me by mail too alias superfifi).

I have two cases

• By using the dll provided by the Magicknet website
  With the magicknet dll, it works well on my pc which has vs2k5 but it does not work on the customer pc
  I took the error
  System.IO.FileLoadException: Could not load file or assembly 'MagickNet, Version=1.0.0.3, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Cette application n'a pas pu démarrer car la configuration de l'application est incorrecte. Réinstaller l'application pourrait résoudre ce problème. (Exception from HRESULT: 0x800736B1)
