Use CreateProcess instead?

function WinExecAndWait32(FileName: string; Visibility: integer): integer;
 { returns -1 if the Exec failed, otherwise returns the process' exit
   code when the process terminates }
var
  zAppName: array[0..512] of char;
  zCurDir: array[0..255] of char;
  WorkDir: string;
  StartupInfo: TStartupInfo;
  ProcessInfo: TProcessInformation;
begin
  StrPCopy(zAppName, FileName);
  GetDir(0, WorkDir);
  StrPCopy(zCurDir, WorkDir);
  FillChar(StartupInfo, Sizeof(StartupInfo), #0);
  StartupInfo.cb := Sizeof(StartupInfo);
  StartupInfo.dwFlags := STARTF_USESHOWWINDOW;
  StartupInfo.wShowWindow := Visibility;
  if not CreateProcess(nil,
    zAppName, { pointer to command line string }
    nil, { pointer to process security attributes }
    nil, { pointer to thread security attributes }
    False, { handle inheritance flag }
    CREATE_NEW_CONSOLE or { creation flags }
    NORMAL_PRIORITY_CLASS,
    nil, { pointer to new environment block }
    nil, { pointer to current directory name }
    StartupInfo, { pointer to STARTUPINFO }
    ProcessInfo) then { pointer to PROCESS_INF }
    Result := -1
  else
  begin
    WaitforSingleObject(ProcessInfo.hProcess, INFINITE);
    GetExitCodeProcess(ProcessInfo.hProcess, Result);
    CloseHandle(ProcessInfo.hProcess);
    CloseHandle(ProcessInfo.hThread);
  end;
end;

or if you really want to, use ShellExecuteEx because it also returns the Process handle. With the handle, you can use WaitforSingleObject to wait for completion.
