Hi all,

I have installed the new Draftsight 2015 free but when I run the program, I have a message:

"Le point d'entrée de procédure DwmInvalidateIconicBitmaps est introuvable dans la bibliothèque de liens dynamiques dwmapi.dll"

(English: "The [DwmInvalidateIconicBitmaps] procedure entry point  isn't found in the [dwmapi.dll]  dynamic link library ")

and the Start panel is everytime here, even I remove it and re-start Draftsight!

What is the problem with my Vista, please? does exist a solution?

Thanks for your reply in advance.
