Can you check if the "py" command is available?
You can run py -0, and it should list which versions you have installed.
However, if you get 'py' is not recognized as an internal or external command, operable program or batch file., you should make sure you have python installed from python.org, preferrably 3.10.8. With the py launcher option enabled in the installer.

Hi so sorry for my late reply, I've trying different way. So where should I type "py -0" in Windows command prompt? yes I got the message mentioned, strange cause i have another Python software running properly, but I see that python is included in his folder. So what shoild I do in this case?

You should install python 3.10, This one is recommended.

I installed Python 3.10, but the command "py -0" still throws an error. When I type the command "python --version," it shows Python 3.10.13. Consequently, installation files do not run, even if I change "py" to "python" in them. It still gives an error that an unknown key -V.

You don't need to make any changes, the warning just indicates that py isn't found, and it falls back on your default python install through the python command. You do not need to make changes to the launch scripts.

Thanks for the answer. I was able to run the program.
