[py-dev] allow installation on windows with not-admin account

[Harald Armin Massa]

Hello,

setup.py fails on windows with limited users because

k = _winreg.OpenKey(reg, key, 0, _winreg.KEY_WRITE)

is not allowed (raises windows error)

I suggest to patch with try, except within py\misc\_dist.py lines 94ff
as follows:


def addbindir2path():
    if sys.platform != 'win32' or not winextensions:
        return

    # Add py/bin to PATH environment variable
    bindir = os.path.join(sysconfig.get_python_lib(), "py", "bin", "win32")
    reg = _winreg.ConnectRegistry(None, _winreg.HKEY_LOCAL_MACHINE)
    key = r"SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
    path = get_registry_value(reg, key, "Path")
    path += ";" + bindir
    print "Setting PATH to:", path
    try:
        set_registry_value(reg, key, "Path", path)
    except WindowsError:
        print "could not write new path to registry. permissions?"
        return
    #print "Current PATH is:", get_registry_value(reg, key, "Path")

    # Propagate changes throughout the system
    win32gui.SendMessageTimeout(win32con.HWND_BROADCAST,
        win32con.WM_SETTINGCHANGE, 0, "Environment",
        win32con.SMTO_ABORTIFHUNG, 5000)

    # Propagate changes to current command prompt
    os.system("set PATH=%s" % path)
