Searching forever on HP's site, I couldn't find a link to the latest 2.0.0.0 version of their HP USB Key Utility for Windows. The updated utility is 64 bit and is needed for the latest HP Service Pack for ProLiant as the size has creeped up larger than a single layer DVD. The product page exists but doesn't have a download button:

Going through their FTP site I was able to find a download link:
