my windows 2000 wont install anything? windows update wont work... virus?

[crashtest]

i have a fresh copy of windows 2000 professional installed on my computer.

Everything i go to microsoft update and try getting all the updates it never works?

i tried also installing my ipod shuffle cd with no success either, i get a message 1607: unable to install installshield scripting runtime... i cant figure it out either....

nothing is working right at all on this thing?

why wont the updates work and why cant i install my ipod software?

Try reinstalling 2000 again and if you don't have service pack 4, I suggest you download it and apply it. You only need SP4, you can skip 1,2 and 3 since 4 contain previous fixes.
