windows 7 upgrade error 0x80070570

[Ryan]

Whilst trying to install the windows 7 upgrade from windows vista I get the
following error message about half way through! 0x80070570!

I have tried several times and each with the same result!

The compatibility passes each time and all updates appear to be there!

Please help

This is not an "update" issue. You are performing an OS upgrade, not a
patch/update on a Windows system.

Make sure your Windows Vista system is up to date, clean of
malware/viruses/trojans, defragmented, CHKDSK'd and all Windows 7
incompatible applications have been removed.

I suggest uninstalling any/all third party firewall applications, removing
your antivirus application temporarily (while upgrading and
OFFLINE/physically disconnected), uninstalling any applications you don't
use at all/often and can re-install after the upgrade easily, backup your
personal data (favorites/bookmarks, emails, contacts, pictures, music,
dcuments, etc) and perform a CHKDSK followed by a defragmentation after a
good antimalware scan or two.

Then try your upgrade.
