This is a WinXP installer but works for Vista and 7 if installed correctly. See the guide below:
1. Copy the installer bundle to the root of your C:\ drive.
2. Open the folder and make the Setup app, XP Compatible and Run as Adminstrator for ALL users.
3. Run the Setup app. When asked for the location, choose the 'Common Files' folder inside the Programs folder. If you don't, the programs folder will stop the install and it will fail.
4. Once complete, reboot.
5. Choose the new Utility that has installed and select 'Configure using WZC'.
Now use Windows Config to connect to your network.
