Actually I finally got it to install (not sure how), but I'm having other issues. I installed sample data, and on the homepage when I hit search with default filters I get this error page:
Call to undefined method JApplicationSite::isClient()
Also in the back-end when I hit "Manage Properties" within the component I get this error:
0 Call to undefined method JApplicationAdministrator::isClient()
I've installed this on a fresh Joomla install and it works fine. However I would like it to work on this existing site, but I'm guessing some other component is possibly breaking it. Feel free to make any changes you need to, this is just a staging server, and I have a backup of the site. I'm creating the ticket now.

I am afraid that you should upgrade your Joomla vesion to newer version, because your current Joomla version 3.6.5 is too old, and it doesn't support some new core functions (is being used in OS Property)
