 Question, would I use the following to enable interrupt 18?  

Hwi_enableIER(0x0012)

You've almost got it.  0x12 = 18 dec = 10010 binary.  But, that argument corresponds to a bit mask, so this will enable interrupts 1 and 4.

I think you should use something like this to enable interrupt 18 (NMI):

        int intNum = 18;        

        int enableMask = 1 << (intNum - 1);
        key = Hwi_enableIER(enableMask);
