I'm racking my brains trying to apply service pack 2 to a recently installed SQL Server 2005 installation on a Windows Server 2K3 64-bit
The error message from the installation is unhelpful:
MSP Error: 1260 Windows cannot open this program because it has been prevented by a software restriction. For more information, open the event log
The event log says:
Source: MsiInstaller Message body: The description for the event ID (11260) in source (MsiIntstaller) cannot be found.
I've already reviewed microsoft kb=979302, whilst the suggested errors don't entirely apply so the hotfix won't work - I did try the registry change but the value of the ErrorMessageFile was correct.
