I cannot mount .dmg file for VMWare Fusion installer. I get the error: **Protocol wrong type for socket** .

I have Mac OSX 10.11.5 , which is newer than the officially supported versions of Mac for this installer. Hard to believe that is the problem though since [this page](http://www.vmware.com/products/fusion-pro/compare.html) says Fusion8 is designed for El Capitan.

I tried downloading both VMWare Fusion 8.1.0 and also 8.1.1 and neither will work. Test, I am also a administrator account on my machine. Maybe I am not a true administrator (since this is a work machine)?

I have no idea what that error means? Is there a way to manually extract a .dmg or some alternate download or method to unzip on command line ?
