Hi,
I understand the frustration. But maybe you can download the version of VMware Fusion that has the VMware Tools (and unfortunately also mcafee) in the download of the installer?
The link is here: Download VMware Fusion 6
As for your download problem, I don't know if it is always happening for you or just today?
It is also possible that the problem originates with a CDN problem, it might be an akamai node having problems and hence not able to offer your download.
Otherwise your troubleshooting with turning off little snitch sound fine.
FWIW, my rules on little snitch are:
VMware Fusion.app allow outgoing to port 443 on ueip.vmware.com and softwareupdate.vmware.com
hope this helps,
