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
http://www.mathworks.com/support/solutions/en/data/1-694YPG/index.html?solution=1-694YPG
You should login as administrator and also run Matlab as administator (right click it), and then you can daqregister('nidaq'). It worked for me.
