Why I can't make a standalone EXE??

[milk]

I got five presentations and 2 mp3 files in the folder , and I did it this way:

1. Open 1 presentation of 5, then use File/Pack and Go
2. Pick the active presentation and the other 4 to pack, choose desktop as
the destination, then choose include linked files and embed fonts, then check
the 'Don't include the Viewer' box and save it.
3. Double click the PNGSETUP.EXE, paste the "seven files" and create three
files by Notepad as the instructions show.
4. Run the 'iexpress wizard', and do what this website
(http://www.indezine.com/products/powerpoint/ppxp/ppt2exe2.html) teaches

but finally, I can only open 1 presentation. It says that it couldn't find
the other 4.
Does anyone know which step goes wrong?

Thanks.
