Installing Plone 5.1.5 on Windows 10 :nameError ' ITYPE 'is not defined'

Hello to the community,

I have been trying for some time to install, under Windows 10 Plone 5.1.5.
But at the end of the installation process, I get the following error message:
'NameError: name' ITYPE 'is not defined'.
I tried to install on another Windows 10 PC also for the same final result.
I strictly followed the instructions to prepare the installation of plone 5 under Windows.
I enclose all the script saved during the insllation.

Can you please tell me if I missed something?
Thanks in advance.
A.

It looks like there's a bug in the installer that crops up when you specify an "--instance=" flag.

It also looks like you don't need to be using that flag: the result will be the same if you omit it. So, you may work around the bug by omitting the "--instance=..." option from your command line.

We'll get the bug fixed in the next release.
