Try the following and let me know. Make sure take SoftwareDistribution folder backup in different drive.

regsvr32 MSXML3.dll /s
net stop wuauserv
cd /d %windir%\SoftwareDistribution
rd /s /q DataStore
net start wuauserv
regsvr32 softpub.dll
regsvr32 mssip32.dll
Go to services and stop the Windows Update service
Go to the Windows directory (default is c:\Windows) and rename the "SoftwareDistribution" folder to "SoftwareDistribution.old"
Go to services and start the Windows Update service

If still it is not fixed try reboot the host after the above task is completed.
