Question: Getting warning that code is not installed properly...
Answer: Make sure that agent module is published and it's in same position as other modules visible on your website's front-end.
Some templates do not have positions in which there can be any widgets placed.
In this case, iif you're using wordpress, you can add this wodpress "shortcode" which renders the content of the agent module:
<?php do_shortcode('[extraWatchAgent]'); ?>
This is demonstrated also on second wordpress demo video featured at:
