Do you have a device drived by the Traditional NI-DAQ in your computer? Some devices can be controlled either by DAQmx, or by Traditionnal DAQ. The PCI-7061E is one of those devices (see NI-DAQ 7.0 Readme, in the chapter NI-DAQmx and Traditional NI-DAQ Devices).
See here to get information about how to swicth from a driver to an other.
Cordially,
