That's too bad; you may be out of luck.  It's possible that someone has 
compiled the .pyd library in such a way that it does not need the 
instruction set extensions.  I'm sorry but I don't know how to find out 
except by trying internet searches - or by downgrading to earlier 
versions of Numpy hoping to find one that works and also can be used by 
the other libraries/programs that need to use it.
