Windows 7 does not "see" the Arduino Uno R3 board in its device manager

I'm not sure if this is the right place to ask such a question, but I have ideas. I connected the Arduino Uno R3 board to my laptop via USB and I am trying to install the Arduino drivers, but for that I need to see it on mine Device Manager

. And here's the problem because I can't see anything that could be my Arduino board. I don't even have a category Other Devices

or node Unknown Device

. Also, the Arduino ON LED is off. I have Windows 7 Home Edition.

I found a solution to my problem:

  • Click the button Start

    and type in the search box hdwwiz

    . Click hdwwiz.exe

    and the wizard will open.
  • Select Install hardware I select from a list

    .
  • Select from the list below Ports (COM & LPT)

    .
  • On the next screen, you can select Arduino

    in the left box.
  • In the right field, you can choose your type Arduino

    .
  • You can click Next

    to try to install the drivers automatically, or you can click Have Disk

    and point to the drivers FTDI USB

    located for example. C:\Arduino\drivers\FTDI USB Drivers

    depending on where you installed the package Arduino 1.X.X

    ( http://arduino.cc/en/Main/Software#toc2 )
  • After the installation is complete in Device Manager

    you should see a Ports (COM & LPT)

    node and a subnode in it called eg. Arduino Uno (COM3)

    ...
  • Right click on it and follow the instructions in the section 4 Install the drivers

    described at http://arduino.cc/en/Guide/Windows .


PS Before you follow the above solution , uninstall the Arduino software, unplug it from the board, and make sure FIRST connect the board to your computer and NEXT install the Arduino software. This can also be useful in some cases.

I got a similar problem, you can fix it from Device Manager. The solution was to select "Let me pick from a list of device drivers on my computer" as soon as you right click and try updating the driver. I got this solution from here: http://eestuffs.com/2017/01/19/fix-arduino-driver-install-problem/

I had a similar problem, the IDE was not showing port selection or detecting my board. So, I just installed dpinst-amd64.exe from the driver folders in the arduino config folder. {your path}: \ arduino-1.8.3-windows \ arduino-1.8.3 \ drivers and install dpinst-amd64.exe

It works fine for me on windows
