Check the HTTP SSL service and see if it is set to Disabled. If so set it to Manual. Then check the World Wide Web Publishing service and make sure that it is started. After that see if Contact Store will start. This may not impact Contact Store but it does stop UMS from installing/working so you might want to give it a shot.
