If any one is clueless as to where to put your exporter, look here:
When the .zip file is open, move all of the contents into your hard drive. For me, I had to move it to mycomputer-hp_pavilion (C:). You can place it anywhere there, but I prefer putting it there right when you open your hard drive.
That's your hard drive. Then open up blender, go to file-export and check if the .dts thing is there.
If you need more clarification for this, tell me.
