I downloaded and installed DAQmx version 8.7.2 with FRC LV at the suggestion of NI tech support. FRC LV still works fine and I was able to use the 6009 test panel to capture analog traces of the encoder outputs.
You can find DAQmx here:

it's a no cost add-on.
The test panels are easy to configure and use - I got it up and running in an hour or so. I guess it depends on what you are trying to do with the 6009.
