MS SQL Server 2008 Service Pack 2 (KB2285068) Error Code 84C40007

I've been trying to install this update via Windows Update, however, every time it begins the installation, it gives me this Error Code 84C40007. When I check the update history, it shows this update has "Failed" to install.

I haven't done anything beyond this, however, I have downloaded the same update from the MS site and am thinking of just installing it manually. However, I'd like to find out why it keeps failing to install through Windows Update and what this error code means?

I've never had problems installing Windows updates before so am not sure why this suddenly came up. I would appreciate any help.

Just to add, I did install one other update (KB2447568) at the same time through Windows Update and everything went smoothly. That update installed with no problems at all.

My specs:

Operating System: Win 7 Professional

System Type: 32 bits

Anti-virus: Microsoft Security Essentials (the most current virus and spyware definitions)
