I have a vague recollection of having this issue upgrading my ID41 and, from memory, the upgrade software didn’t like the way I had the Ethernet port configured in Parallels.

I think I solved this by giving Windows its own IP address via DHCP from the Parallels configuration options rather than sharing the IP address the Mac is using (you’ll need to shut down the virtual machine before Parallels will let you make this change).

I’m not sure how relevant this is here as I think the upgrade software might be different, but mentioning it in case it helps...
