You need to create your own sub-key, with any name, under the PythonPath 
key and add your path there.  The reason is that Python only looks for 
that root key when it can't sniff the location of the library itself 
based on the location of the executable - and in most cases it can. 
Python does however enumerate and use the sub-keys in all cases.
