How do I activate my trial version of BackupExed?

You install the license for the DB agent on the media server. You then install the remote agent on the remote server via push install or manual install.

Once done, open up Backup Exec on the media server, browse to the remote server and you will see Exchange or SQL, depending on the application running there.

The Remote Agent facilitates comms between the remote server and the media server and the license allows the media server to see the particular and supported app.

Thanks!

For all remote servers, regardless of what you want to backup from them, there is only one software to install and that is the remote agent referenced in the screenshot of your previous post.  This remote agent contains all the capabilities to backup anything, but these capabilities are only unlocked when you installed the appropriate agent licence on the media server.  For example, you need to backup a SQL Server database on a remote server.  You push out the remote agent to this remote server, install the Agent for Applications and Databases agent licence on the media server and then select the SQL Server Agent option.  You can then backup the SQL Server database.  If later you install Exchange on this remote server and want to backup Exchange, you just install another Agent for Applications and Databases agent licence on the media server and then select the Exchange option.  You can then backup Exchange.  There is no need to push out the remote agent software to the remote server again.
