Cannot start installation on Windows 10

Unpack the latest version Plone-5.2.10-UnifiedInstaller-1.0.zip on a custom "Plone" folder.
Run CMD with admin rights, and then run:
windows_install.bat standalone --password=admin

Immediately receive the following message:

D:\Plone>windows_install.bat standalone --password=admin
D:\Plone>python helper_scripts\windows_install.py standalone --password=admin
Creating target directory \Users\m.rossi\Plone
Traceback (most recent call last):
  File "D:\Plone\helper_scripts\windows_install.py", line 108, in <module>
    os.mkdir(opt.target, 0o700)
FileNotFoundError: [WinError 3] Impossibile trovare il percorso specificato: '\\Users\\m.rossi\\Plone'

I miss something ?
