M$ doesnt support xp 64 for the zune. I had a 8gb version previously and had to change alter the vista 64 version to get it to work for xp 64. Now I need to install this software once again on my new 120gb version of the zune.. I tried doing this process over again. I had to remove any old version of the zune software from my hard drive to do this. Zune isnt on my add/remove list. And trying to install the software w/o doing this process wont over ride the old zune software. Is there any way of deleting the files w/o having to reformat my hard drive?
