arduino nano R3 problem

Hi
Thanks for the real quick response.

I tried both suggestions…
I think I have different problem.
My computer does not recognize the nano at all, it doesn't make a sound when I plug or unplug the USB, and it doesn't show the Arduino at the device manager at all.
(it's just blink)

The Nano uses the FTDI chip for serial communication.
You will need to install the FTDI drivers. Get the latest drivers here: http://www.ftdichip.com/Drivers/VCP.htm

Because i can't see the device in the device manager I could not choose the Arduino from the device manger and right click on it and install the drivers (is there any other way for doing it?).

Option 2: Use my installer that sets all the drivers automatically http://goo.gl/KF7E9 hehe

I also tried the ERW 1.0.1 software and it doesn't recognize the port either, as before

Any suggestions?
Thanks
