From memory, I installed the app and it went through the install process, then a second install process kicked off, it looked more like an executable unpacking some files. Then I connected the xcal and and the standard windows driver install window came up, and I selected search for driver automatically (or what ever it said close enough) - it found the drivers and installed them ok. I would be looking to see if you can see any the driver files or directories and manually point the xcal to it when you plug it in. if not try and uninstall any instances you have of livelink, and then re-run through the install from the herrod website.
