You are correct, it is possible that it is something very simple.
The 6229 is a (relatively) new M series card, which is only compatible
with the latest drivers (NI-DAQmx). In the case of the older E series,
they are compatible with both the new NI-DAQmx and the legacy
Traditional NI-DAQ. From your error, it seems that you were programming
in Traditional NI-DAQ, which would cause the error you are seeing. That
second computer probably does not have Traditional DAQ installed, or
cannot detect any Traditional NI-DAQ compatible hardware.
The way to verify is to see if your PCI-6031E was programmed using
Traditional NI-DAQ (which seems to be the case, since your error code
mentions NI-DAQ and not NI-DAQmx). If so, then it will not work with
