Und wie versuchst du es?
ShellExecuteAndWait(Application.Handle, 'open', PChar(fName), NIL, Nil, SW_SHOW, True); bzw.


Delphi-Quellcode:
Function ExecAndWait(Filename, Params: String;
                     WindowState: Word = SW_SHOWNORMAL): boolean;

var
  {$IFDEF UNICODE} ShExecInfoW: SHELLEXECUTEINFOW; {$ENDIF}
  ShExecInfoA: SHELLEXECUTEINFOA;
// MSDN: ShellExecuteEx, ShellExecuteInfo
  Win32IsUnicode : Boolean;

begin
  Result := false;

  Win32IsUnicode := False;

  if (Filename = '') {or not FileExists(FileName)} then
    exit;
  {$IFDEF UNICODE}
  if Win32IsUnicode then
  begin
    ShExecInfoW.Wnd := GetForegroundWindow;
    ShExecInfoW.cbSize := SizeOf(SHELLEXECUTEINFOW);
    ShExecInfoW.fMask := SEE_MASK_NOCLOSEPROCESS;
    ShExecInfoW.lpVerb := 'open';
    ShExecInfoW.lpFile := PWideChar(WideString(Filename));
    ShExecInfoW.lpParameters := PWideChar(WideString(Params));
    ShExecInfoW.lpDirectory := PWideChar(WideString(ExtractFileDir(Filename)));
    ShExecInfoW.nShow := WindowState;
    Result := ShellExecuteExW(@ShExecInfoW);
    try
      if Result then WaitForSingleObject(ShExecInfoW.hProcess, INFINITE);
    finally
      CloseHandle(ShExecInfoW.hProcess);
    end;
  end
  else
  {$ENDIF}
  begin
    ShExecInfoA.Wnd := GetForegroundWindow;
    ShExecInfoA.cbSize := sizeof(SHELLEXECUTEINFOA);
    ShExecInfoA.fMask := SEE_MASK_NOCLOSEPROCESS;
    ShExecInfoA.lpVerb := 'open';
    ShExecInfoA.lpFile := PAnsiChar(AnsiString(Filename));
    ShExecInfoA.lpParameters := PAnsiChar(AnsiString(Params));
    ShExecInfoA.lpDirectory := PAnsiChar(AnsiString(ExtractFileDir(Filename)));
    ShExecInfoA.nShow := WindowState;
    Result := ShellExecuteExA(@ShExecInfoA);
    try
      if Result then WaitForSingleObject(ShExecInfoA.hProcess, INFINITE);
    finally
      CloseHandle(ShExecInfoA.hProcess);
    end;
  end;
end;
