Last few weeks my computer has influenced by virus and I have formatted my computer and reinstall the Windows again. When I want to install Microsoft Office 2007, I do not know what is going on this software CD, it kept showing the error cause I cannot fully install Office 2007. I guess may be my DVD-ROM cannot read the CD and that’s why I went to buy a new ones. Yes, finally I successfully installed Office 2007 in my computer by using new CD. Thanks god!
