How do I get Office XP SP3 to install successfully?

[DaJudge]

I have tried 3 times to download and install Office XP SP3, including the
slower method requiring the CD. In each case the download proceeds, but the
installation fails. There is no other error message.

See http://support.microsoft.com/default.aspx?kbid=839191 "'Installation
unsuccessful' error message when you try to install Office XP SP3 from
the Office Update Web site".
