i have matlab 2012a and i want to use ni daq so i typed 'daqhwinfo" and error message appeared
Error using daqhwinfo (line 42)
To learn about using data acquisition devices on the win64 platform,
see the documentation on the session-based interface.
when i typed "daq.getVendors()" it gives
%Data acquisition vendor 'National Instruments':
ID: 'ni'
FullName: 'National Instruments'
AdaptorVersion: '3.1 (R2012a)'
DriverVersion: 'unknown'
IsOperational: false
%Warning: Diagnostic Information from vendor: NI: There was a driver
error while
loading the MEX file to communicate with National Instruments
hardware.
It is possible that the NI-DAQmx driver is not installed or is older
than
the required minimum version of '9.1'.
Additional information:
'Invalid MEX-file
'F:\mat12\toolbox\daq\daq\+daq\+ni\private\mexNIDAQmx.mexw64': The
specified module could not be found.'

Looks like first thing to do would be to look at versions for the driver installed and updates and perhaps a reinstallation.

Hello Mado,
did you manage to resolve your issue? It seems I have the exactly the same one. My drivers are up to date but I still get the same error. If you have an idea why the error appears it will be of great help.
I am using Windows 10, 64-bit and installed the latest drivers from NI (v15.x). The device appears to work properly from the device manager.
Many thanks
Andreas
