Not for me it didn't - doesn't recongnise the device - sucks I have to reboot to xp
I have not tried it on Vista64, but it makes sense tha it would not work. I have Vista Enterprise and it works on that system, it is not 64 bit though.
V3.0 and V3.01 wouldn't work on my laptop with Vista, but I remembered the compatability tab under properties for the castlelink.exe. I choose Win XP (service pack 2) and did the exe. with the compatiability and it works fine now.
