Hi Francois,

not sure if it is different on windows, on linux I simply do:

  import gettext
  gettext.install(domain, localedir)

to install _() into my application's global namespace,
where localedir in your case was "c:\myappfolder\Translations".
The path that contains the french translation should be "..\fr\LC_MESSAGES" instead of "..\francais\LC_MESSAGES"
I think (at least that is true on linux).

I hope this helps
