The page is divided into two sections:
If you have started the TPDU without administrator rights, then you have the opportunity to add them here.
- Click on Run with Elevated Privileges, to proceed with admin rights (arrow). This button is only visible if the TPDU is running without admin rights.
Only then, will the fifth tab – Licenses – appear provided that license keys are installed locally, or the address of the license server is specified in a ThinPrint component.
