Starting with FRC 2017, the cRIO is no longer supported. Your best bet would be to use FRC 2014. I believe that is the year we set the LabVIEW for FRC license to not expire. I would also suggest you use a dedicated machine for FRC 2014 and cRIOs - not try to install it alongside FRC 2017.
You can find the 2014 software at the bottom of this post:
