- Launch Analytica. If you haven’t already, run the Analytica installer. Leave the Activation Key blank, or select the Free Player option.
- From the top right Help menu, select Update License… dialog:

- Your Host ID and User ID can be found at the bottom of the Licensing dialog.
Centrally managed licenses:
If your are activating a centrally managed license (usually a floating license), you need to enter the host ID for the computer running the RLM server. To find this, from the RLM server administration panel (usually at http://localhost:5054), press the System Info button. Host IDs are listed. Usually many are listed, pick one. If a Disk Serial Number is listed, use it, and when entering above, please note that the “disksn=” prefix IS part of the host ID, so you need to include that prefix when entering. If no Disk Serial Number shows, an Ethernet host id should be used.
