There is no 'Python tree' on windows. Rather, there is a separate tree 
for each version, located where the user directs.
Windows used to have a %APPDATA% directory variable. Not sure about Win 
7, let alone 8. Martin and others should know better.
Or ask the user where to put it. I know where I would choose, and it 
would not be on my C drive. Un-installers would not delete (unless a 
reference count were kept and were decremented to 0).

Making a new top-level directory without asking is obnoxious.
