[tex-live] Install failed on Windows 8 (*.win32 packages involved)

[Denis Bitouzé]

Hi,

with an admin account, I try to install TeX Live 2013 on a Windows 8 PC:

 - both with the official DVD and with an up to date .iso,

 - both with install.bat and install-advanced.bat,

 - run as both normal user or admin),

 - in both default (C:\texlive\2013) and customized (C:\Users\jdoe)
   locations,

 - with virus scanner (Aavast) enabled or disabled (at least I guess it
   was disabled).

All failed when installing the 1st (and sometimes the 2nd or 3rd)
*.win32 package with the following typical message:

--8<---------------cut here---------------start------------->8---

Do you see a workaround?

Thanks by anticipation.
