[MiKTeX] Is YaP (MiKTeX2.2) bugged ?

[Robert C. <rc...@on...>]

Hello !

I just downloaded the essentials of MiKTeX's last version.
Everything works fine, except Yap who refuses tu treat Type 1 fonts 
(apprently).
I can't know exactly if this Yap's or MakeTeXPK's problem.
All I can obtain is a Windows error message from the latter (compelling 
for an illegal instruction).

What happens ?
