yes, format your harddrive and get rid of all the pre-installed crap :)

Seriously: in my experience simply disabling antivirus/firewalls doesn't
work properly - there's always something that stays enabled. And some of
those bastards won't even uninstall properly.
A little story: a while back when I was still using XP on a (now very
outdated) laptop I had a hd crash. So after getting a new drive I
installed a fresh copy of XP, and as a second step I installed a
firewall tool (very popular, and for reasons beyond me it still is).
After that I wanted to install visual studio. Well, I *wanted*, but the
firewall wouldn't let me: it immediately replaced files that the VS
installer replaced in the system32 folder again with the 'original'
versions. Ok, so I disabled the firewall. No luck. I uninstalled the
firewall - still no luck. A web search showed that the uninstaller would
not remove everything (since it attached itself so deep in the OS that
it couldn't remove itself anymore).
All that I was left with was to format the hd and install XP again.
Needless to say that this was the last time I *ever* installed a
firewall or virus scanner ever again.

The error message you get is clear: the installer tries to copy a
required (and even digitally signed by MS!) file to the system and
something doesn't allow that. You have to find out what this is - I
can't help you here, sorry.
