Keep in mind that these may be data acquisition VI's. When LabVIEW is put on a machine, it doesn't contain the data acquisition VI's that access the NI-DAQ driver. When NI-DAQ is installed, it detects what version of LabVIEW you have, and installs the appropriate data acquisition VI's into your LabVIEW directory.
If you have just upgraded LabVIEW, be sure to uninstall your previous version of NI-DAQ and install the current version of NI-DAQ, which will update not only your 6.0i version, but your 7 Express version of LabVIEW as well.
