need help installing Arduino drivers.

I am installing my Arduino through USB. The problem is I jumped the gun and when I first plugged the Arduino into my USB I ignored the "Found New Hardware drivers" and let the computer detect it.
Now I need to install the drivers for the Arduino but the "Found New Hardware drivers" window won't pop up.
I don't know how to install the drivers now without the "Found New Hardware drivers" window popping up. Can someone explain what I need to do to install the drivers.
I have already downloaded the drivers.

Thank you.

If you are referring to the FTDI drivers, then the easiest way would be to go download the latest Windows driver as an exe from the FTDI website here: http://www.ftdichip.com/Drivers/CDM/CDM%202.04.16.exe

Then run the installer, Windows should find the device and apply the driver to it.

If you don't want to install the driver that way, you could alternatively go to "Device Manager" in Windows:

XP:

  1. Click Start
  2. Click Settings
  3. Click Control Panel
  4. In the Control Panel double-click the Systems icon.
  5. In the System Properties window click the Hardware tab.
  6. In the Hardware tab click the Device Manager button.

Vista

  1. Click Start
  2. Type "Device Manager"
  3. Click Device Manager at the top of the search menu
  4. Select OK if you are prompted.

Most likely there will be an "unknown" device that is highlighted yellow, or has a mark of some sort on it. Windows usually opens the category for you so that you can see devices that are not installed properly.

You should be able to right click and delete the device. Then you can plug it back in, and you should be good to go. If plugging it back in does not find it, then you can right click the "computer name" at the top of Device Manager, and "Scan for changes".

HTH,
