Officially Win XP Pro is required for AC10 (the same requirement was true for AC9) but there are users using it on Win XP Home and it works without problem.
But I am not sure about Win2000 - it is an older platform.
Hopefully someone who actually uses it under Win 2000 successfully answers this thread.
