I am using Windows 7 Ultimate and I have installed Nero 10 on my computer. When I tried to set the configuration of default burning software in UltraISO 9.3.6.2750 by clicking "Detect" button, this message appeared: "Nero or Roxio burning engine not found." Is this a bug??? Or doesn't UltraISO 9.3.6.2750 support Nero 10 yet??? Though it isn't not important issue, but I hope you fix it ASAP. Thanks.
