Additionally, 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 as explained in Modify Tekla Structures license access rights (tekla.opt). This can prevent situations where there are no licenses available for users that need them because someone else has reserved or borrowed a license that they do not really need.
When you renew licenses and when you need to make hardware changes on the license server, you must deactivate your licenses as explained in Deactivating Tekla Structures licenses.
If your licenses have become untrusted or disabled, they cannot be used and you need to repair them. For information about how to do this, see Repair a Tekla Structures license.
