This is what I typed as a solution a little earlier (before you posted at 11:28):
I think the update in question is KB2344911, which is an Office update.
You can download & install it manually. Download from Win Catalog click here (search for it there - copy & paste it so you don't get it wrong)). Download & unzip it (using any unzip program like 7-Zip click here for instance). Double-click on the unzipped file to install. Reboot your PC when it completes. G
Go to Services and Applications RC Manage Rxpand the Services and Applications Click on Services Find Windows Installer RC Select Properties.Select diaable. Reboot computer and do it all again but return Disable to Manual
Hope that will help someone
