I offer this as a way to go if win32 is installed.

import string
def msvc_get_paths(path, vNum='6.0', platform='x86'):
        "Get a devstudio path (include, library or bin)"
        try:
                import win32api
                import win32con
        except ImportError:
                return None

        L = []
        if path=='bin': path = 'Path'
        path = string.upper(path + ' Dirs')
        for base in (win32con.HKEY_CLASSES_ROOT,win32con.HKEY_LOCAL_MACHINE,
                     win32con.HKEY_CURRENT_USER,win32con.HKEY_USERS):
                try:
                        k = 'Software\\Microsoft\\Devstudio\\%s\\Build System\\Components\\Platforms\\Win32
