Installing the Ardunino Mega Driver on Windows 7

Goal: Installing the the Ardunino Mega device driver on Windows 7.

The automatic driver install process for Windows 7 might automatically install a Microsoft Windows version of the Arduino Mega driver. This is not the driver LANforge expects. These instructions will guide you how through uninstalling an old driver and installing the new driver.
 
  1. You want to install the windows version of the LANforge Server beforehand.

    For more information see Installing LANforge Server on Windows

  2. This process requires you to operate the Control Panel as Administrator. Some patch-levels of Windows 7 have secured this. A useful work around for this will be discussed shortly.

    5. There will be an Other devicesUnkown Device entry. Right-click on it. If the options menu only gives you Scan for hardware changes or Properties, you might need to restart your control panel as Administrator, that is discussed next. screenshot

    6. If you have recently removed a driver, you might need to reboot your Windows system for it to complete the driver installation process.
