Can´t get Arduino to communicate with my computer.

I can't get the Arduino nano to talk to my pc. I´m using blhelisuite 13.2.0.0 and should be able to select com port but there is no option when I click on port. On ver 13.1.0.0 it´s a clear option where I can select comport as you can see in this video (5 min and 37 sec in)
SN20A ESC How to Flash BLHeli ESC Linker/Arduino Nano - YouTube .
On version 13.2.0.0 that option is gone as you can see in the picture.

Please help me if you can I compleatly new to Arduino.

Is your Arduino Nano a clone from Ebay ? then it has the counterfeit FTDI chip. Google for: FTDI 2.0

Mm, most Nano's nowadays have a CH340....

septillion, you are right. I searched on Ebay and it was hard to find a cheap Nano with counterfeit FTDI chip.
redrobjem, look at the backside. If you see a CH340G chip, then use the driver in link by septillion. If you seem something else, then it is a counterfeit FTDI chip.
