Googling for the error "Requested Python version () is not installed" returns posts that suggest Python has not been installed correctly so I would suggest removing then reinstalling Python38. I'm pretty certain this is not a script issue but that something is wrong with your Python installation, perhaps you installed it as one user and are now trying to run it as a different user? Maybe try (re)installing Python38 so that it's available for all users (there's a checkbox for this option during the installation)? Also make sure you're installing the correct 32/64 bit version.
