- The installation path of ESP-IDF and ESP-IDF Tools must not be longer than 90 characters. Too long installation paths might result in a failed build.
|

- The installation path of Python or ESP-IDF must not contain white spaces or parentheses.
|

- The installation path of Python or ESP-IDF should not contain special characters (non-ASCII) unless the operating system is configured with "Unicode UTF-8" support.
|

System Administrator can enable the support via Control Panel - Change date, time, or number formats - Administrative tab - Change system locale - check the option "Beta: Use Unicode UTF-8 for worldwide language support" - Ok and reboot the computer.
