Note: If the computer or virtual environment is no longer available to deactivate Tableau Desktop or Tableau Prep Builder (for example the computer was lost or stolen), you can activate by signing into Tableau Cloud or Tableau Server using login-based license management, or use the product key on a new computer. You can activate Tableau Desktop on up to two different computers if they are used by the same person and one computer per user for Tableau Prep Builder.
If you are using Tableau Desktop or Tableau Prep Builder in an environment with login-based license management, you do not need to deactivate any product keys if you want to move your installation to another computer. If you no longer need Tableau Desktop or Tableau Prep Builder on a computer or you want to move it to another computer, deactivate the product key before you uninstall Tableau or you may not have the license available to activate on another computer.
