i did a little search for your error, and some other guy had this problem. i am copypasting the answer that worked for him. these are not my words...
source"I had the same problem with all Windows Live products. There's an easier way than reinstalling windows. Go to Start>Run, type 'cmd' and enter each of these one at a time, hitting 'enter' after each one:
regsvr32 wuapi.dll
regsvr32 wuaueng.dll
regsvr32 atl.dll
regsvr32 wucltui.dll
regsvr32 wups.dll
This will fix a variety of problems people have with Windows Live products and other windows update issues like repeatedly getting a message from the security center that automatic updates are off when the automatic updates window says they are on."
