That's basically correct.  Setup sets the file permissions to POSIX
permissions.  Since your screenshot doesn't give enough information, I
don't see why this fails for you.  The entries look basically ok, except
for the fact that the user SID isn't known for some reason.  Output of
the Windows cacls command would have been more informative.

Usually you don't have to.  Your user account is known to your
own machine, so I don't understand why it doesn't show the correct
user name.

Maybe, what setup should do is either to leave permissions alone when
downloading the package files, or the permissions for the package files
and the package directories should always be set to 664, so that the
group (usually Administrators) has always write permissions.
