The batch files in "build\scripts-2.2" do not have double 
quotes (") around the name of the python executable, 
and they should. This works if python is installed in a 
folder with no embeded spaces, and fails otherwise. 

I.e.  if python is in "C:\python2" then it works
however if python is in "C:\Prog Files\python" then it 
failes because the embeded space in the path causes 
problems.
