I understand that MATLAB 32 bit is not officially supported on 64 bit platforms, but my MCC device runs properly on INSTCAL on Windows 7 64 bit machine.

When executing daqhwinfo, I do not see MCC.

Running 32-bit MATLAB on 64-bit Windows is a supported configuration as-of R2010b. In R2010a and earlier, this configuration is not supported, but is expected to generally work.

In order for Data Acquisition Toolbox to configure the MCC interface, it must be run once in admin mode, and run the command daqregister.

Data Acquisition Toolbox 2.15 (R2009b) is not officially supported on Windows 64 bit.

Installing MATLAB 32 bit can be a workaround and the result may vary with different devices.

For Windows 7 and Windows Vista, please ensure you run MATLAB in administrator mode. The Data Acquistion Toolbox need admin privileges to communicate with the device.
