Installing Data Acquisition Toolbox blockset in 64 bit Matlab simulink 2012b

Dear All,

I have Matlab 2012b with the data acquisition toolbox. However I wish to use the data acquisition toolbox blockset within matlab simulink so that I can use a national instruments daq card.

On opening simulink, the daq blockset doesn't appear and the command "daqlib" doesn't work since it appears to be incompatible with the 64 bit release.

How do I get the blockset running in simulink?

Thanks very much

Pete
