Reboot loop on Windows Vista

Instructions

Problem description

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

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

Solution

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 an issue in the Windows Vista version of Windows Update, service packs are often not successfully installed automatically. To solve the problem, you must manually download and install the Service Pack.

Service Pack 1 is available here: http://www.microsoft.com/en-us/download/details.aspx?id=910

After installing Service Pack 1 we highly recommend installing Service Pack 2, which is available here: http://www.microsoft.com/en-us/download/details.aspx?id=15278
