Does not launch on 10.11.4

Running OS X 10.11.4 and iTuned 12.3.3 this app fails to launch. After starting connections to 3 or 4 different domains including DoubleClick, it gives an English-like message about iTunes not being active. My iTunes works just fine. Tried both with iTunes open and not already open.
