Automatic Uninstallation

This will automatically send the Uninstallation Key to the Bayesia License Server and remove the BayesiaLab license from your current computer.

Upon completing this process, your Single-User/Single-Machine License can be installed and activated on a different computer using your original credentials.
Manual Uninstallation
