Cannot register Execution Agent as Windows Service

Hello!

We have:
1. Windows Server 2008 R2 x64
2. Advanced ETL Processor Ent (trial)

During installation process we check "Register Execution Agent as Windows service" and Management Console as Service, but only one service were registered - Management Console. We tried to register agent form Console. No results. All our attempts to register Agent resulted in nothing. We cannot register Execution Agent as Windows Service. Because of it we cannot run scheduled jobs. No error in Windows Event Viewer.

Can you help us to resolve this problem?
Thanks

This is by design.

Agent is only available once license key is installed.

OK, I see.
Thanks.
