Problem with MATLAB and NI-DAQ 6212 BNC

In Matlab

daqhwinfo yields

ans =

            ToolboxName: 'Data Acquisition Toolbox' 
         ToolboxVersion: '3.1 (R2012a)' 
          MATLABVersion: '7.14 (R2012a)'
       InstalledAdaptors: {'winsound'}

OS: Windows 7 (64 -bit); 
Matlab version R2012a (32bit)

daqregister('nidaq') yields

Unable to load adaptor: C:\Program Files (x86)\MATLAB\R2012a\toolbox\daq\daq\private\mwnidaq.dll. 
Driver files or DLL for the specified adaptor could not be found or are not installed.

I have installed NI-DAQmx version 9.4, but I installed it after MATLAB was previously installed. Do I need to reinstall MATLAB?

thanks in advance .

Hi Daniel,

Whats the output of

daq.getVendors

This is a session-based interface command, but could give you more hints on what's wrong.

Hi Daniel

I had the same problem. The solution is described in

You should login as administrator and also run Matlab as administator (right click it), and then you can daqregister('nidaq'). It worked for me.

Worked like a charm, thank you!
