Engadget tried installing the Zune software onto a good PC, and apparently it was riddled with bugs, excessive registration forms, and it even crashed a bunch of times and failed to recognize the Zune device at some points. Sounds like utter crap.
In the mean time, we let Microsoft know what was up and they were pretty quick to help figure out what was behind this whole nightmare install. We don't yet know, but hopefully it's something small and limited to our Media Center PC -- because if it isn't, tomorrow's big launch is going to be a comedy of errors straight up tragedy.

One of the crash pix.

At least they are having fun in this pic!
edit: sorry, this could have been added to the other thread, even though it is a different story.
