title: what can i do to solve Webots error message
body: <p>I'm new to webots program and I'm building a new robot controller, but when I hit the start simulation button, it gives me this error :
  WARNING: "python3.8.exe" was not found.
  Webots requires Python version 3.7 or 2.7 (64 bit) from python.org in your current PATH.
  To fix the problem, you should:
  1. Check the Python command set in the Webots preferences.
  2. Check the COMMAND set in the [python] section of the runtime.ini file of your controller program if any.
  3. Fix your PATH environment variable to use the required Python 64 bit version (if available).
  4. Install the required Python 64 bit version and ensure your PATH environment variable points to it.</p>
