Can't use Windows Update - Error number: 0x8DDD0004 - Corrupted fi

I can't use Windows Update b/c of Error number: 0x8DDD0004. I read a post
that suggested checking my Downloaded Program Files folder for damaged files,
and I did find one whose status is "Damaged. When I look at its properties:

Type: ActiveX Control

But I don't know what to do about it! How can I fix this so that I can
update my OS? I'm running XP SP2.

Downloaded and installed file Unk suggested.

Also used "Firefox" to download 3 updates and installed.
After reboot was able to use IE to update rest of files.

When I click on JeffJJ's link below, it prompts me to save or open - if I
open I'm presented with 4 files (iuctl.cat, iuctl.dll, iuctl.inf,
iuengine.dll). But I don't understand - what am I supposed to use with them?
Unk's URL took me to relevant articles in Google Groups, but I didn't see
info on how to use the above files...
