This article on how to install Esptool on Windows 10 was written because I remembered that I had been for a time wondering how to do it. If you’re a Windows user, you’re probably used to graphical interfaces. You’re also used to easy installs – download an installer file, run or open the file, follow the installation instructions, and it’s done.
Installing Esptool is a two-part process. First you download and install Python. Then, you run a Python command to install Esptool.
pip install esptoolEsptool runs on the scripting and programming language Python. Therefore, we need to install Python first before we install Esptool.
How to Install Python
On Windows 10, you may simply type “python” on the Windows search box beside the Windows Start button and download Python from the Windows App Store. An issue with this procedure is that you may get an older version of Esptool from the App Store.
If you want to get the latest version of Python, downloading the installer from the Esptool download page is the way to go.
Run the downloaded Esptool installation file. As of this writing, the installation file for the latest version is python-3.8.1.
You may want to put a check mark on the Add Python 3.8 to PATH before clicking on the Install Now button. This will make it easier to start the Python and the Esptool program. Without the check mark, before you can run Python or Esptool, you would need to find the directory where you installed Python. You then would have to change your current directory to the Python’s folder.
How to Install Esptool
After successfully installing Python, open a command prompt window.
Type cmd on the Windows search box and click on the Command Prompt app. Then type the command pip install esptool.
pip install esptool
A successful Esptool installation will look like the screenshot below.
Testing the Esptool Installation
A quick test of the Esptool installation can be done by issuing the command esptool.py version.
esptool.py version
Congratulations! You now have Esptool installed and ready for use on your ESP8266 or ESP32 development board.

You should consider upgrading via the ‘c:\python39\python.exe -m pip install –upgrade pip’ command.
Any idea why it is erroring? I’m not very conversant with low level programming or Python.
I had a similar error, i reinstalled the program and it now seems to be working
try pip install –upgrade pip
Very informative and i like the main thing that you describe advantages and disadvantages very well-kept posting such informative topics.
