    I'm just starting to "play" with esp32 so don't beat me up for a beginner's question.
    I'm having trouble compiling a simple "hello world.
    What I've done: installed the latest Python and Git for Windows. From https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html I downloaded the latest installer: esp-idf-tools-setup-2.3.exe, during the installation I selected esp-idf v4, manually added the location to cmake to the PATH (the installer didn't do it).
    Trying to compile (idf.py menuconfig) "hello_world" with "esp-idf\examples\get-started\hello_world" gives an error as below:

    Any ideas what is wrong?

    Cannot find or there is a corrupt compiler file for xtensa-esp32.

    And how specifically? Do you follow this instruction?

    The editror is OK, I have made use of this instruction. I think the errors are with the PATH variable.
    I found a temporary workaround for the problem. When I type "idf.py menuconfig" in the "cmd" window I get errors as above, but when in the same window I issue the command
    Code: text Expand Select all Copy to clipboard
    path C:/Program Files/Java/jre1.8.0_241/bin/server;C:/Program Files/Java/jre1.8.0_241/bin;[tutaj reszta ścieżki];C:\esp32\esp-idf\tools;C:\esp32\esp-idf;C:\esp32\eclipse
    .
    then the program compiles without errors. This solution only works until the computer is restarted and only in the directory with the specific project. Changing to another project (changing the directory) causes errors.
    Path after "path" copied vividly from the window "sysdm.cpl/Advanced/Environmental variables.../PATH".
    How to turn the "workaround" into a permanent solution?

    The problem was bad characters in the PATH variable, swapped slashes and backslashes. In the registry it looked like this: „C: /esp32/.espressif/tools / ...”, while it should look like this: „C: /esp32/.espressif/tools / ...” Manual replacement helped.

    I ran first "install.bat" o later "export.bat". The problem was the wrong characters, confused / with (not sure if inserted wrong by the installer or by me).
