Active X Update Failure - One solution

Hi! I've been wrestling with this for several weeks (and many hours of
browsing) trying all the recommended solutions to on avail until
today.

My eventual solution was in the recommendation to re-register the
following files:
Softpub.dll
Wintrust.dll
Initpki.dll
Urlmon.dll

It wasn't until today that I noticed the the first one was not
succeeding!

So I did a search for the softpub.dll and found although it existed it
was in C:/Windows/System32/dllcache and it wasn't in
C:/Windows/System32

So I copied it from dllcache up one directory level, and reregistered:
regsvr32 softpub.dll which then succeeded.

Windows update now works again for me, as does Office update, which
started failing many weeks ago (and the problem was previously posted
here).

Thanks to all those who have replied and I hope this helps some of
many others of you who have posted this problem.

Any ideas as to why my softpub wasn't where it should be would be
welcomed!

Cheers
