I have had similar issue with Windows 10 Host, VM Workstation 12 Pro and CenOS 7 Guest.
# mount -t vmhgfs .host:/ /var/www/html/pcdb
mount: unknown filesystem type 'vmhgfs'
The solution (run on the guest):
# /usr/bin/vmhgfs-fuse /mnt
And magically, shared FS is mounted under /mnt.
You can look for `/usr/bin/vmhgfs-fuse --help´ for information how to mount if you have more than one filesystem shared from the VM host.
