hello, I can not check the option "Direct Slipstream" when trying to add the Office 2007 Professional, I can not add updates or service packs and less extra files, but with Microsoft Office 2003 if I can do it, why? Ahh, and I tell you, very good version 1.4 of nero 9 lite, for the next version adds Microsoft Visual C + + 2005 SP1 Redistributable to the installation so it is easier and looks better, bye and thanks! Sorry For My Bad English!
