After the initial licensing setup, you need to make changes in the following situations:

• You can ensure that the correct types of licenses are available to the users who most need them by defining access rights for using and borrowing licenses, see Modify Tekla Structures license access rights (tekla.opt)
• You need to deactivate your existing licenses :
  
  • When you start using a new version of Tekla Structures , which requires activating renewed licenses.
  • When you make hardware changes that affect the license server.
• If your licenses become untrusted or disabled, you can repair them a limited number of times as explained in Repair a Tekla Structures license.
