Problem registering devices for data acquisition (mcc and winsound)

Using USB-1408FS from Measurement Computing.
Besides Matlab (see version info below), also have the following installed:
- DASYlab software version 11.0
- instaCal version 6.10
When I try to register the adapter mcc for daq with the daqregister('mcc') command, it seems to succeed:
>> daqregister('mcc')
ans =
'mwmcc.dll' successfully registered.
But when I then try to define an analog object I receive an error:
>> ai = analoginput('mcc',0);
??? Error using ==> analoginput.analoginput at 142
Failure to find requested data acquisition device: mcc.
Checking further, I get:
daqhardwareinfo = daqhwinfo
daqinstalledadaptors = daqhardwareinfo.InstalledAdaptors
daqhardwareinfo =
ToolboxName: 'Data Acquisition Toolbox'
ToolboxVersion: '2.18 (R2011a Prerelease)'
MATLABVersion: '7.12 (R2011a Prerelease)'
InstalledAdaptors: {} %%empty%%
From this, I understand that the mcc adapter is not installed/registered.
I have tried the same thing using 'winsound' instead of 'mcc' and get the same results.
What am I doing wrong?
TIA.

Are you logged into Windows as an administrator? In order to register an adaptor you must be logged in with administrator privileges. Once you register the adaptor it can be used by all users.

Yes, registering the adaptor just a one time configuration - once it works you won't need to repeat it again.
I'm sorry that my first suggestion didn't help. I'm not sure what's wrong. You could try installing the new version of MATLAB (R2011b) that was just released to see if that resolves the issue, or contact <http://www.mathworks.com/support/contact_us/index.html technical support>

Yosh, you will also have to run MATLAB in administrator mode. Refer to this solution : http://www.mathworks.com/support/solutions/en/data/1-5SAEJ8/index.html
