Try this.

In a cmd.exe shell:

type setup64.exe > foo.exe

I did a cmp and the two files were identical (using 32 bit setup.exe).

I also tried in bash:

$ cat setup.exe > foo2.exe

Again the files were identical.  However, ls showed permission for foo.exe
(made under cmd) as rwx while foo2.exe made under bash was rw-.  Both open
fine from Windows Explorer.
