Arduino software is needed to program Arduino boards and must be downloaded from the Arduino website and installed on a computer. This software is known as the Arduino IDE (Integrated Development Environment).

Drivers must be installed in order to be able to program an Arduino from the Arduino IDE. This article shows how to download and install the Arduino IDE software and drivers on a Windows 10 computer.

Downloading Arduino for Windows 10

Go to the Arduino Software download page where you will find two downloads for Windows – Windows installer and Windows ZIP as shown in the image below.

Selecting an Arduino Software Download

You can choose either of the two Windows options, but I prefer to use the ZIP file because it keeps the Windows system cleaner. The Windows Installer version of the software will download an installer which will install the software into the Windows system. The Windows ZIP file allows you to unzip the Arduino IDE to any location of your choice and easily remove it if you want by simply deleting the unzipped folder.

This installation guide uses the Windows ZIP file, so download the ZIP file and proceed to the installation step below. After clicking the download link, you will have the option of making a donation to Arduino or just downloading the file for free.

Installing Arduino Software on Windows 10

After downloading the Arduino Windows ZIP file, simply double-click it and then copy the folder from inside the zip file to the desired location. I prefer to copy it to my desktop.

To avoid any confusion: the file that is downloaded is a file and not a folder, although it is called a 'Compressed (zipped) Folder' in Windows.

Running the Arduino IDE

Open the folder that you extracted from the zipped file and double click arduino.exe in the folder to start the Arduino IDE software. If you can not see file extension (the .exe on the file name), turn them on in the file manager by clicking View → File name extensions.

If you want to create a shortcut to the Arduino IDE on your desktop, start dragging the arduino.exe file to the desktop and hold down the Ctrl + Shift keys before dropping it on the desktop. This will create a shortcut to the Arduino IDE instead of moving the file to the desktop.

Make sure that you have not moved the arduino.exe file by looking at the name of the file on your desktop which should contain the word 'Shortcut' at the end. You can rename this shortcut to just Arduino or Arduino IDE.

Installing Arduino Drivers in Windows 10

Strongrising port devices driver updater

When you plug an Arduino board into a Windows 10 computer, a driver should automatically be installed for it. The driver configures the Arduino as a virtual COM port which can be seen in the Device Manager.

Open the Device Manager window by right-clicking the Windows 10 start button in the lower left of the screen and then selecting Device Manager on the menu that pops up.

In Device Manager, expand Ports (COM & LPT) and you should see a COM port which will be your Arduino as shown in the image below. If you have other COM ports on the PC, then unplug the Arduino to see which COM port disappears from the device manager, then plug the Arduino back in and see which port appears – this will be the Arduino port, e.g. COM4 in the image below.

The drivers that come with the Arduino software can be installed instead of the default Windows 10 driver, which is explained next.

Installing Arduino Drivers

In the Device Manager, right-click the COM port that was identified as the Arduino (the Arduino must be plugged into the computer first). Select Update Driver Software... from the menu that pops up.

Updating Arduino Driver in Windows 10

In the dialog box that opens, select Browse my computer for driver software.

Browse for Arduino Driver Software

In the next dialog box, make sure that Include subfolders is checked and then click the Browse... button.

Browse for Driver

In the dialog box that pops up, navigate to the drivers subfolder of the Arduino folder that you unzipped earlier. Click the drivers folder to select it and then click the OK button.

Select the Arduino drivers Folder

Back in the Update Driver Software dialog box, the correct path to search for the drivers is set. Click the Next button to start the driver installation.

Start the Arduino Driver Installation

In the Windows Security dialog box that pops up, click Install.

Confirm the Arduino Windows 10 Driver Install

After the driver has been installed, a dialog box will appear that shows that the driver has been successfully updated and will display the Arduino COM port number.

Arduino Driver Installation / Update Finished

Finally back in the Device Manager, the COM port is now identified as an Arduino when the Arduino driver from the Arduino IDE folder is installed.

This article will guide you how to correctly install VAG-COM 409.1 KKL USB cable on Windows and VCDS software.


In our experience, we don't recommend depending on VAG-COM 409.1. Because it's functionality is extremely limited. In addition — you'll need to pay extra $97 to upgrade free VCDS-Lite software to full version. And even if you do upgrade — it can only scan vehicles made up to year 2004.

For that reason we recommend to get the complete VAG-COM 2020 cable with original, unlocked and full version of VCDS software from Ross-Tech™ — by clicking here.

STEP 1: Download and Install VAG-COM KKL 409.1 Drivers

(DO NOT connect cable to your computer yet. Only do this when you're instructed below.)

Start by downloading the VAG-COM Driver Pack 1.

Here's how to install on different Windows versions...

Windows Vista, 7, 8, 8.1, 10:

Uncompress the file. Double-click on 'Install.exe' to install the drivers. When complete — plug in cable into any USB port on your computer and wait for automatic installation to complete.

If install is successful, move onto Step 2.

If installation fails, see below: Troubleshooting: If Drivers Failed To Install

Windows XP:

  1. Uncompress the file. Double-click on 'Install.exe' to install the drivers.
  2. Plug cable into any computer's USB port.
  3. 'Found New Hardware Wizard' will start and it will ask you 'Can Windows connect to Windows Update to search for the software?'. Select 'Yes'.
  4. Select 'Install the software automatically'.
  5. After the installation is complete, click 'Finish'.
  6. 'Found New Hardware Wizard' will start once again because there are two drivers for this cable.
  7. Go through the same steps as explained above to install this second driver.

If install is successful, move onto Step 2.

If installation fails, see below: Troubleshooting: If Drivers Failed To Install

If the COM port number is between 1-4, then everything is fine. Move onto Step 3.

If the COM port number is above 4, then we'll have to change it so it's between 1-4. Here's how...

Right-click on 'USB Serial Port' and click on 'Properties' — as per below pic:


  1. Click: Port Settings
  2. Click: Advanced
  3. For 'COM Port Number' — you MUST choose any number between 1-4.

That's it! Now let's test if everything is working. Move onto next step below...

Cable should be plugged into computer.

  1. Start VCDS-Lite software.
  2. Click 'Options' button.
  3. You will see 'Select COM Port' box. Select the 'COM Port' number as explained in Step 2.
  4. Click the ‘Test’ button.
  5. If everything is good, it should display 'Interface Status: Found!'.
  6. You can now connect other end of cable to car. Turn on ignition. And you're ready to start diagnosing!

If test is not successful — check the following:

  1. Other software or devices using USB ports or that same COM Port could be conflicting. You should uninstall the suspected software or device for troubleshooting this problem.
  2. It should be noted that VAG-COM 409.1 KKL cable does not work on vehicles running on CAN-BUS System.
  3. Cable must be plugged into the vehicle with ignition ON.
  4. Test the cable with each COM Port from 1 to 4 in Windows Device Manager.
  5. Make sure that the driver is installed and configured as explained in Step 1.
More Troubleshooting Tips:
