XP SP2 upgrade - hidden files ??

[the big show]

Hi,
I am running XP Home sp1 and wish to upgrade to sp2.
When attempting to run the upgrade I get an error of the sorts "cannot
find the file tcptest.exe". The upgrade will then fail. I have run a search and can see tcptest.exe within
the search but I cannot browse to it or copy it etc. I cannot even point the install to it. It seems to be hidden.

I have seen some similar posts on SpywareInfo - Hope you can help.
