First of all you will need to download the installation files from VMware official site https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/
Open the terminal and go to the directory that the bundle has been downloaded to:
# cd ~/Downloads
Then you will need to make sure the permissions are correct by running the following command:
# chmod +x VMware-Player-12.0.0-*.bundle
Then you will need to run the installer using the command:
# sudo ./VMware-Player-12.0.0*.bundle
For the free version you just need to add an email and then run through the installation.
