Hello,
It appears like the IVI Compliance Package you is not installed correctly. Try to run a repair installation of it.
However, it should be noted that FGEN 2.0 only works on LabVIEW 6.1 and up, so you won't be able to use it with your version of LabVIEW.
You can download an older version of NI-FGEN from the following link which will work with LabVIEW 6i:
