Been trying on my 64bit Win 7 laptop and desktop. Tech Support says its only compatible up to Vista 32bit and XP 32bit, no 64bit Win 7
and no plans for it to be as the Waris series ( HT/EX/CDM) series is on the long,slow,cruel chopping block anyways
Ended up returning our 2 new Win 7 laptops and scouring for used XP laptops with serial comports.
Good luck!
