Ask the numpy people. I am surprised since a reason to be using 64 
rather than 32 bit python is to have objects larger than 2 gigabytes and 
memory larger than 4 gigabytes. Numerical/scientific programming is 
relatively likely to need such.

If you look on your C: drive, you should have both 'Program Files' and 
'Program Files (x86)' directories. The latter is for 32 bit programs.
