Can't help as I don't use PC Anywhere (use
VNC instead - you could try that as it's free, but since you already own PC Anywhere it's not much help. is it?), but just want to point out that you can't patch something that's not there.

So I can't see how installing the patch(unless it changes some win2K files rather than PC anywhere files) first will help.
Surely Symantec have instructions for the patch?
Cheers
