The installation guide is a bit confusing.
Normally when installing USB devices one installs the driver / software first. However, the guide advises to plug in the modem first and then the installation auto starts. This is clearly nonsense because the hardware doesn't have any drivers embedded.
Start again by first uninstalling the device and drivers.
Install the drivers first and then plug in the device. The installation will begin and the correct drivers should be installed.
After installation has finished click the Reliance Netconnect shortcut on the desktop and enter username and password.
NOTE : I suspect the above drivers are not for Windows 7 32bit and are for Vista 32bit. Therefore the drivers will first need to be installed in compatibility mode
