I cannot mount .dmg file for VMWare Fusion: Protocol wrong type for socket ERROR 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 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 ?
If you can't even mount the .DMG file it is unlikely to have anything to do with VMWare or the software they put in the DMG file. Usually errors when mounting a DMG file occur due to a damaged download. Though it is possible the file they placed on their servers is corrupted at the source.

Try downloading with a different browser or even use WGET in the terminal and see what your results are.
