Tableau Offline Activation ((better)) -

Tableau allows you to activate a product key on a machine that is permanently or temporarily disconnected from the internet. This is essential for secure, air-gapped environments or servers without web access. The process involves generating an activation request file on the offline machine, moving it to an online machine, obtaining a response file from Tableau’s servers, and finally applying that response file to the offline machine.

If you need to move a license from an offline machine to another, you cannot simply uninstall the software. You must deactivate the key. tableau offline activation
