Windows XP Professional Service Pack 2 Update

I want to install SP2 on my system, but when I run Windows Update it comes up
with "No Updates Available." The computer does have SP1 loaded and I have
loaded all other available updates. What could be causing this problem and
what can I do?

I would hesitate to install it. I have installed it on 2
computers and have had trouble both times. Programs just
won't run, etc. I have a critical software that is now
down, and the software company has no idea how to over
come whatever SP2 did to it. Stay with SP1 and be Happy.
