function ExecAndWait(const FileName, Params: ShortString; const WinState: Word): boolean; export;
var
  StartInfo: TStartupInfo;
  ProcInfo: TProcessInformation;
  CmdLine: ShortString;
begin
  CmdLine :=Filename+ Params;
  FillChar(StartInfo, SizeOf(StartInfo), #0);
  with StartInfo do
  begin
    cb := SizeOf(StartInfo);
    dwFlags := STARTF_USESHOWWINDOW;
    wShowWindow := WinState;
  end;
  Result := CreateProcess(nil, PChar( String( CmdLine ) ), nil, nil, false,
                          CREATE_NEW_CONSOLE or NORMAL_PRIORITY_CLASS, nil,
                          PChar(ExtractFilePath(Filename)),StartInfo,ProcInfo);
  if Result then
  begin
    WaitForSingleObject(ProcInfo.hProcess, INFINITE);
    { Free the Handles }
    CloseHandle(ProcInfo.hProcess);
    CloseHandle(ProcInfo.hThread);
