Hi Andreas,
thanks for answering.
Miktex 2.9 is OK and working with WinEdt. I did what you told and all is ok, i'm able to find the right directory to mikteX/bin. But I guess Winfig should auto-detect it and it doesn't, and I can't find where I can manually set it in Winfig.
I think that maybe an reinstallation of winfig should work ?
Best regards,
Florent
