How can I get the plug-ins for DPS 2015 to load with Indesign CC 2015?

I am receiving this error code and would like insight into why and how to fix it:

DPS Desktop Tools for Adobe InDesign CC 2015

Before you install this, can you check whether or not you have the 'Overlays' panel in the Windows menu.

Also, if you open a document and go File > Export, do you see 'DPS Article' in the available format
