Windows could not install the drivers for my Uno

Hello!

I've tried to install the drivers for my Arduino Uno because when uploading a program to the board I get this error:

avrdude: stk500_getsync(): not in sync: resp=0x00

When I plug in my Arduino Uno ( says NHduino UNO on the board ) to my PC, using Windows 7 x64, it shows up in the Device Manager under Other Devices as USB2.0-Serial. After trying to install the drivers by navigating to the right folder correctly, I get the message "Windows could not find software for your device".

Going crazy for the past 4 days, can someone help me with that?

It looks like it has a CH340 USB to serial converter so you will need the drivers from here.

As soon as I connected the NHduino, it appeared as COM4, but the driver was not installed. So I run the exe provided here and it installed automatically. Then I could upload the sketches even faster than with the Nano, that uses FTDI for USB communitacion.

I’m using W7 32bit.
