Speaking from experience, I recommend that you NOT nail the corners to the living room floor, carpeted or not. When the Cootessa wandered in, barefoot to see what the pounding was, and tore her foot open on a litte finishing nail, I thought my time had come.
I suggest stretching the ropes in the garage/basement and laying it over those, with an oscillating fan running. Be sure to allow for some air exchange wherever you put it. Mildew can show up fast!
