Licensing VMware Player for Linux fails
Unable to license VMware Player for Linux
Environment
VMware Player 5.x (Linux) VMware Workstation Player 14.x (Linux) VMware Player 6.x (Linux) VMware Player 7.x (Linux) VMware Workstation Pro 15.x (Linux) VMware Workstation Player 12.x (Linux) VMware Player Pro 7.x (Linux)
Cause
In some instances, installing from the command line using sudo does not elevate the installation to the correct permissions. As a result, the license key entry field does not display.
Resolution
To resolve this issue, you must manually invoke the serial number entry.
Run this command to open the Enter License Key dialog:
sudo /usr/lib/vmware/bin/vmware-enter-serial
To ensure this issue does not occur on a new installation, use these best practices:
When installing VMware Player for Linux, log in as root (and not just using sudo privileges). Logging in as root ensures that the license key entry box displays correctly.
For Ubuntu, from a console, run sudo su. For other Linux distributions, from a console, run su. Enter your password when prompted, then proceed with the installation of VMware Workstation.
