The initial setup wizard advances to the TAS Activation Key screen:
Without a license key, TAS supports only single-user mode, with which you can evaluate TAS. You need a license key to add users to TAS. Each time you start TAS and execute a server daemon, TAS verifies the identification number of its host server, checks the licensed user limit, and, if applicable, checks the expiration date of the license. Contact your Sun Microsystems sales representative to purchase additional licenses. After you successfully configure TAS, you do not need to enter the license key if you re-run the initial setup wizard.
