VMware Workstation "Enter License Key" Button Doesn't Work

On VMware Workstation 9.0.2 running on Linux Mint 15 Olivia, “Help > Enter License Key > Enter License key” doesn’t do anything.
To enter your license key, run this command:

sudo /usr/lib/vmware/bin/vmware-enter-serial

A window will then pop up prompting for your license key, which you may now enter.
