If end up using version 3.5 or 4.0, try to use the Client Profile version.
If you are using anything earlier than 4.0, make sure you distribute the app.config file that appears alongside your built application.
Thank you, now I test it in Windows XP Mode.
I think I'll release the WinXP version when I'll finish working on byte reordering.
