MATLAB: Am I getting undefined function errors

Instrument Control Toolboxmissing toolboxundefined function

Below is a snippet of my Matlab console window. Matlab can find the file in question, but it will not run it. I've gone through the answer here, but that does not help. What am I doing wrong here?
>> which -all instrhwinfo
C:\Program Files\MATLAB\R2012a\toolbox\shared\instrument\@instrument\instrhwinfo.m  % instrument method
>> instrhwinfo('serial')
Undefined function 'instrhwinfo' for input arguments of type 'char'.
>> instrhwinfo
Undefined function or variable 'instrhwinfo'.
>> help instrhwinfo
 --- help for instrument/instrhwinfo ---

   [...]
    Example:
        out1 = instrhwinfo
        out2 = instrhwinfo('serial');
        out3 = instrhwinfo('gpib', 'ni');
        out4 = instrhwinfo('visa', 'ni');
        out5 = instrhwinfo('visa', 'ni', 'gpib');
        obj = visa('ni', 'ASRL1::INSTR');
        out6 = instrhwinfo(obj);
        out7 = instrhwinfo(obj, 'AdaptorName');

When James typed ver into the Command Window, the result showed only the version of MATLAB and did not include the Instrument Control Toolbox and so he will have to obtain it again.
