If you receive the following licensing error, simply create your Windows 2012 or 8 VM as a custom VM. It appears the Express/Easy Install feature of VMware fusion does not work with the most recent version of Windows yet. Simply booting from the ISO will work fine.
Windows cannot find the Microsoft Software License Terms. Make sure the installation sources are valid and restart the installation.
