Imagemagick & ASP

I've just installed the OLE Object from Imagemagick. It works. But now, I want to get some informations about an image trough the identify command.

I've tried:

SET oImg = Server.CreateObject("ImageMagickObject.MagickImage.1")
vReturn = oImg.Identify("c: emplogo.jpg")

There is no error, but vReturn is always empty?
What did I wrong?
