Handling and Troubleshoot Tabeau License.

Before you reach out to the vendor you can try all the possible troubleshooting steps for addressing the licenses. To know the exact error code OR to identify the error you can use the Utility called
tabinstallck.exe  Fortunately this utility exists in bin folder on primary server.

NOTE :You can also use tabadmin to perform these licensing tasks, but in order to do this Tableau Server must already be deployed and configured, so tabinstallck.exe provides a way to script the licensing step for a new Tableau Server installation that is not completely configured.

Using scripting languages or manual operations via the Command Prompt, you can activate online, refresh, and deactivate your license keys. To use tabinstallck.exe, you need to run the commands or script as an administrator on the primary Tableau Server node.

Activate	start/wait tabinstallck.exe -activate <product_key>
Refresh	/wait tabinstallck.exe -refresh <product_key>
Deactivate	start/wait tabinstallck.exe -return <product_key>

@echo off
start/wait tabinstallck.exe -activate <product_key>
if %errorlevel% EQU 0 (ECHO SUCCESS) ELSE (ECHO FAILED)

Error Handling:

After you run the script error logs are stored under file tabinstallck.log . This can be under programdata folder which is hidden most of the time else you can search with the file name.

If activation was successful, the exit code is 0 (zero). The table below lists exit codes from the activation process and what they mean.

Exit Code	Message	Value
536871012	TABLEAU_ERROR_LICENSING_GENERAL	An unknown error occurred during the licensing operation.
536871013	TABLEAU_ERROR_LICENSING_INTERNAL	The product is unable to start due to an internal licensing error.
