Matt is correct. The watchdog and system state publisher should be installed with the LV Real-Time module.
In general, software for your target comes from three sources. In any case, it always has to be present on the host machine first.
1. The LVRT module - quite a few packages come with the module itself, like the ones mentioned above.
2. Drivers - Many drivers include real-time components. For example, if you wanted to use DAQmx on a Real-Time PXI system, you would first install DAQmx for your host system, and the real-time driver would come along. For cRIO, the main driver you'll need is NI RIO, but there are a couple of others such as the IndCom (EtherCAT) driver.
3. Individual packages - fairly uncommon, but there are a few cases where you can download something that just contains a package for your LVRT target, this would be an example
