esptool.py not recognized as internal or external command, operable program or batch file

I recently tried to load MicroPython on ESP8266 board, but failed. To do that I had to install esptool. I successfully installed it but when I wanted to use it, it would not work.

For instance,

esptool.py --help
'not recognized as internal or external command, operable program or batch file'

I found many questions on this topic, but none of the answers helped me. I tried adding everything to the Windows path and it still did not work.

I was in the same position as the OP. On Windows 10 I must use this syntax at a CMD prompt launched as an admin:

py -m esptool --help

I'm running Python 3.10.2 and esptool was installed using

py -m pip install --user pip

Try installing esptool using pip command on Windows. Then use only "esptool" instead of "esptool.py"

By using "esptool -h" I could check the help option.
