The installer to upgrade from VMWare Workstation 14.0 to 14.1.12 hits a snag when the installer checks whether the port 443 is available on the local host for the service to listen to. It appears that the installer does not properly shutdown the process vmware-hostd earlier in the install, and so it prompts the user for a different port number.
The simple fix when encountering this error is first to check what is listening to that port:
Execute the command
sudo netstat -pan | grep 443
The first result will tell you what process is using that port:
tcp | 0 | 0 0.0.0.0:443 | 0.0.0.0:* | LISTEN | 3757/vmware-hostd |
Obviously in this case we simply need to stop the vmware-hostd process. If something else is listening to that port, you can identify an open port and provide that value. Otherwise simply kill the offending process and then continue forward:
sudo kill -9 3757
