I think that now they recommend using CreateProcess() instead of
ShellExecute/ShellExecuteEx.

Does the following code work for you?

// Setup to launch:
SHELLEXECUTEINFO execInfo;
memset (&execInfo, 0, sizeof(SHELLEXECUTEINFO));
execInfo.cbSize = sizeof(SHELLEXECUTEINFO);
execInfo.lpFile = m_filename;
execInfo.nShow = SW_SHOWNORMAL;
execInfo.lpVerb = _T("open");
execInfo.hwnd = m_hWnd; // parent window for error messages

// Launch app; abort if failure
if ( !ShellExecuteEx (&execInfo) ) // failed
return (int) execInfo.hInstApp; // return error code

In particular, maybe your flag of SEE_MASK_FLAG_DDEWAIT is screwing it up.
