Hello,
I'm having trouble with the "é" when trying to switch my Windows 7 PCs from static IPs to DHCP. My batch file runs fine manually, but I'm having an encoding issue with WAPT. So I tried replacing utf-8 with cp850:

# -*- coding: cp850 -*-
from setuphelpers import *

uninstallkey = []

def install():
print("Updating IP interfaces")
run (r'reg import DHCP-CLIENT.reg')
run (u'netsh interface ip set dns "Local network connection" dhcp')
run (u'netsh interface ip set address "Local network connection" dhcp')

but I'm back to my encoding problem with the message:
Updating IP interfaces
'ascii' codec can't encode characters in position 42-44: ordinal not in range(128) : faulty string is 'u'netsh interface ip set dns "Connection "on local network" dhcp

Thank you for your help

You should avoid accented characters in run commands as much as possible. Input and output encoding are never truly controlled (this isn't a WAPT problem per se, it's a cmd.exe issue).

It's better to use wmi commands, which are usable in Python, something like this: `

import wmi
nic_configs = wmi.WMI().Win32_NetworkAdapterConfiguration(IPEnabled=True)
for nic in nic_configs:
nic.EnableDHCP()`

And don't forget to check in the package that there's a lease available for your machine before switching over!

Hi,

thanks for the help.
WMI is way beyond my skill level, so I made a little script that runs at login and does the job perfectly.

Cheers!
