Not sure what your real question here is, but I'll take a stab at it.
The NI-CAN drivers (module) only work with the NI CAN cards. If you have a different vendors card, you'll have to contact them to see if they have LabVIEW drivers.
If you do have a NI CAN card, then you just need to install the NI-CAN drivers and you're ready to go. Have a look at the examples for help in getting going.
If you're having a specific problem, please give us some more details and we may be able to help out a bit more.
