My response at bottom:
By *.exe file I mean those ebooks that open by themselves.
I actually now realize that these may not be classifiable as PDF documents
but may be any document that has been somehow presented in a self-displaying
*.exe file.

Try opening it with 7ZIP.
http://en.wikipedia.org/wiki/7zip
7ZIP is used for file compression and decompression. If your .exe
file is a self extracting decompressor of some sort, there
is a remote possibility 7ZIP can decompress it and give you
the payload. But once you have the payload, there is no way
to know what form it is in. Being an ebook, it could be
encrypted and not a vanilla PDF. (For experiments of this
sort, I also keep handy a hex editor, and check the beginning
of the file, to see if it has a format I recognize. For example,
a PDF might begin with %PDF- )
