Hi Varun,
Can provide the exact product name?
Are you looking for Workload Automation AE (AutoSys) or CA Workload Automation DE?
Also, where did you get the free trial version?
Did you download it from the CA Support site?
I will suggest that you contact our Customer Care or Account rep for more information on licensing including any temporary licenses.
Thank you,
Nitin Pande
