Hello,
If the DAQ support has not yet been installed for the version of CVI on your computer, then you will need to reinstall the NI-DAQ driver in order to get it. NI-DAQ 7.0 should be sufficient to program your DAQ card with CVI.
If you were having problems with programs that are available on the web, then you will also want to make sure that the example code was written with both a version of NI-DAQ and CVI that is compatible with what you have.
