You'll have to go through the Windows registry. Please have a look at the following recipe: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/55993 I also have my own routines based on that for getting and setting the path: ################## import _winreg as winreg import win32gui import win32con REG_KEY_PATH = r'SYSTEM\CurrentControlSet\Control\Session Manager\Environment' def set_path(pathval): """Set the PATH environment variable""" try: reg = winreg.ConnectRegistry(None, win32con.HKEY_LOCAL_MACHINE) key = winreg.OpenKey(reg, REG_KEY_PATH, 0, win32con.KEY_ALL_ACCESS) winreg.SetValueEx(key, 'path', 0, win32con.REG_EXPAND_SZ, pathval) win32gui.SendMessage(win32con.HWND_BROADCAST, win32con.WM_SETTINGCHANGE, 0, 'Environment') finally: winreg.CloseKey(key) winreg.CloseKey(reg) def get_path(): """Get the PATH environment variable""" try: reg = winreg.ConnectRegistry(None, win32con.HKEY_LOCAL_MACHINE) key = winreg.OpenKey(reg, REG_KEY_PATH, 0, win32con.KEY_ALL_ACCESS) return winreg.QueryValueEx(key, 'path')[0] finally: winreg.CloseKey(key) winreg.CloseKey(reg) ################## Regards, Ryan Ginstrom -- http://mail.python.org/mailman/listinfo/python-list
