Basic install problem following step by step instructions for NEOS sample

Sorry for asking a probably stupid newbie question, but I run into the same problem installing the NEOS setup from the Installing webpage using MAMP or XAMP on a win10 machine. The composer directive throws this relevant messages:

  • Installing neos/composer-plugin (2.1.3): Extracting archive
    Class Neos\Flow\Composer\InstallerScripts is not autoloadable, can not call post-package-install script
  • Installing composer/package-versions-deprecated (1.11.99.4): Extracting archive
    Class Neos\Flow\Composer\InstallerScripts is not autoloadable, can not call post-package-install script

and

  • Das System kann den angegebenen Pfad nicht finden.

    Type: Neos\Flow\Core\Booting\Exception\SubProcessException
    Code: 1355480641
    File: C:\progs\xampp\htdocs\mySite\Packages\Framework\Neos.Flow\Classes\Core\Boot
    ing\Scripts.php
    Line: 712

Any suggestions are appreciated . Thank you
