URC dropped support for that thing at Vista. It's an absolute train wreck. URC told me they keep a windows 32 bit xp machine laying around so they can connect to it. Isn't it great you can still buy it like new and it is listed as a modern product on their website.

I currently dual boot into windows 7 32 bit. It was installed only only to talk to that singular device. 7-32 bit mode and xp mode (32 bit) can both communicate with it.
