I had the update for .NET 4 refuse to install giving an error. I had to disable my anti-virus program (Microsoft Security Essentials), go into services.msc (as administrator) and then stop/restart the Windows Update service, and then install the update. Restart then the anti-virus.
Hope this helps.
