Hello, i see you ran into some problems with executing programs from
within programs.  I have noticed that over the past few years the
"system()" command had changed, as it used to always wait for the
exe program that was called before executing the next Eu statement.
After a few Eu "updates", that had changed, but you might try
using the system() command with the second param set to 2 such as the
code fragment below.
Also, i think you found a bug in Euphoria's system_exec() command
because as you had said, and i tryed it too here, the system()
command works just fine, whereas the system_exec() command fails
with the very same parameters.  Have to write to RDS about that.
Perhaps there is an easy workaround.  As for now, i use system()
and providing a 2 for the second param provides for needed synchronicity
(You might wish to read up on that too though).
  As a last resort, creating a dynamic .bat file works also.
If you wish to get the short path as a solution, ive included the
C code below too.

atom ret,ink
include get.e
sequence ExwCommand

ExwCommand=34&"exw.exe"&34&" "&
           34&"c:\\america online 5.0\\download\\test.exw"&34

ret=system_exec(ExwCommand,2) --doesnt work!

?ret

system(ExwCommand,2) --works fine!!

ink=wait_key()

The "GetShortPathName()" function obtains the short path form of a
specified input path.
(in kernel32.dll)

DWORD GetShortPathName(

    LPCTSTR  lpszLongPath, // points to a null-terminated path string
    LPTSTR   lpszShortPath, // points to a buffer to receive the null-
terminated short form of the path
    DWORD  cchBuffer         // specifies the size of the buffer pointed
to by lpszShortPath
   );


lpszLongPath:
Points to a null-terminated path string. The function obtains the short
form of this path.

lpszShortPath:
Points to a buffer to receive the null-terminated short form of the path
specified by lpszLongPath.
  You can set lpszShortPath to the same value as lpszLongPath.

cchBuffer:
Specifies the size, in characters, of the buffer pointed to by
lpszShortPath.

Return Value:
If the function succeeds, the return value is the length, in characters,
  of the string stored in *lpszShortPath, not including the terminating
null character.
If the function fails due to *lpszShortPath being too small to contain
  the short path string, the return value is the size, in characters, of the
  short path string. You need to call the function with a short path
  buffer that is at least as large as the short path string.
If the function fails for any other reason, the return value is zero.
  To get extended error information, call GetLastError.

good luck with it,
