Reboot loop on Windows Vista


After installation of or upgrading to Norman Security Suite 10.1, PCs running Windows Vista without any service pack migh experience a reboot loop.  The following error message is given:

"Could not complete the installation or update due to an unexpected error".


The new version of the Personal Firewall in Norman Security Suite 10.1 requires that at least Service Pack 1, but preferably Service Pack 2 is installed. Due to a bug in the Windows Vista version of Windows Update, service packs are often not successfully installed automatically. To solve the problem you need to manually download and install the Service Pack.

Service Pack 1 is available here:

After installation of Service Pack 1 we highly recommend installation of Service Pack 2, which is available here:
