Hi,
That tab is only available when you have the professional version of VMware Fusion.
It is not available on the free VMware Player.
Of course I don't know what version you have, but the above would be the logical explanation.
You can verify what version is installed by going to the about box (menu "VMware Fusion" -> "About VMware Fusion") Down there it says "Professional version 12.x" if you installed a professional license.
