No, as far as I remember it is a windowsfont, but is not in the font-directory. It is a small directory somewhere in Softlogic, but is isn?t named as fonts'directory.I had with 4.1 the same problem, couldn?t even start Pagestream. But after a tip from the pagestream-helplist and removing a windowsfont in that directory the problem was over.
