Johnathon,
Thanks for your help.
I had installed the NI-DAQmx a while ago, so it was the installation order at fault. Although I had been through installation repairs several times for both, it took uninstalling everything then re-installing both to get it to work.
Perhaps the installer could be improved for this situation?
Anyway, now it is installed, and I can have a play around with it. And it is clearer that I have to buy the Professional or Enterprise measurement studio to make use of it.
Regards,
Dave
