Can't build a standalone

[Thomas Bähler]

Dear List
I wanted to save a stack as standalone application but I get
only a dialog window saying "There was an error while saving the 
standalone application".
Nothing else! Doesn't matter whether I want to make PC or Mac 
standalone, or on which Harddisk
I try to save it.
Does anybody have a tip where I should start to resolve this problem?
