“License Has Changed” Warning or Licensing is Lost When Using Tableau Desktop on Virtual Machine

When using a virtual machine with Tableau Desktop or Tableau Prep Builder, you may get a warning message that your license information has changed, or prompted to activate, whenever the application is launched. 
 

Cause

Because Tableau product licensing is linked to the hardware of the host, even with virtual machines, some virtual machines will change physical hardware during an instance restart/reboot. This will, therefore, break any existing licensing. In these situations, the behavior is expected.
