Where are you downloading from? Full URL web address please, then we can try the download.
On a side note...
I don't see a "Microsoft Encarta Encyclopedia Standard 2" listed in Google, (except your own CNET forum post), so I wonder if you have that name wrong. Do you mean "Microsoft Encarta Encyclopedia Standard 2002"?
I do see a Microsoft Encarta Encyclopedia Standard 2002 at Download.com here;
I haven't attempted to download yet until you say whether this is the one you are trying to download, but if this is the one, did you notice that this is for "Windows 98/2000/XP". Windows 7 is not mentioned and that means it may not work on the newer OS.
Every time I try to download, it says your download will begin in a moment and then it never starts. Did everything the video says to do with no results. Using Firefox.
