Don't understand.
Also see p176 of the latest H8000FW User Manual, where we say: "These drivers allow 64 bit operation on either Windows XP or Vista, but this is not
commonly used and is not supported by Eventide."
64 bit OS are more common than when the above prose was composed, but we have little experience with them. We would be glad if H8000FW users who do have experience with XP or Vista 64 would share it with us, so that we can move towards fully supporting them.
