ATHENA 2018 must be authorized within 30 days after the installation. You should carry out the authorization as soon as possible, because in some circumstances it may take a few days until you receive it.

The authorization dialog box is displayed when you first start the program. Here, you have the possibility of requesting authorization and of importing a license file. As long as no license file has been imported, the dialog box is shown once each day as a reminder.

You will find a detailed description of authorization in the Chapter Authorization.
