OK, I think I got the gist of this install... 'cause I'm running SP-4 now with no apparent problems...

What you need to do to make this one work (or at least I did) is:

1) Download the network (read *BIG* - 130 or so megs);
(This way you can ...

2) Shut down ALL programs, including firewalls (read "ZoneAlarm"... I even had to UNINSTALL ZA) and virus software;

3) Install SP-4;

4) Re-install firewall or virus software;

5) Turn everything "back on", and re-boot.....

Long process, but it seems to have worked...
