Nano drivers not working

This is my first time using an Arduino Nano, and I have tried to get the drivers working in so many different ways.

Here is all of the background:

  1. I am using Windows 8.1
  2. The "serial port" option in the Arduino IDE is grayed out.
  3. Under my device manager, the Arduino show up as Other Devices > FT232R UART with a little yellow triangle with an exclamation point inside. When I right click properties, it says "The drivers for this device are not installed (Code 28). There are no compatible drivers for this device. To find a driver for this device, click Update Driver"
  4. I have tried to install the driver by clicking Update driver software > Browse my computer for driver software > and navigating to:
    a. The Arduino drivers folder
    b. The installation from the FTDI website (the newest version)
    c. Every single folder in my C: drive

The error that I have gotten each time is:
"Windows could not find driver software for your device. If you know the manufacturer of your device, you can visit its website and check the support section for driver software."

Does anyone see anything that I missed?
Thank you SO much!
