[AUCTeX] viewing pdf files

[juan mari alberdi]

Hello,

I've pdflatex processed a file activating MiKTeX with C-c C-t C-p. When 
I ask AUCTeX to show the .pdf file, it opens a DOS shell but does 
nothing, just waits for input.
I see that the command in the list 'TeX Output View Style' is 'start 
%o'. How could I change things to make AUCTeX execute my Acrobat 
application?

Thank you for your attention,
Juan Alberdi
