SQL Server 2008 Service Pack 1 installation problem

Question

I am using Windows 7.
Today I saw "Microsoft SQL Server 2008 Service Pack 1 (KB968369)" as an optional update in the updates list. I've tried to intstall it but it failed with Code CF2E222F. I found nothing about this code on the internet.
I've also tried to install the sp manually. I've downloaded it an tried to install. But it also failed.
SQL Server Setup has encountered the following error: C:\Windows\Installer\9bcac.msi.
Any suggestions?
