32 bit update KB2589322 automatic updated on 64 bit system

Please assist. I have a 64 bit windows 7 home premuim and it is set to auto update. I noted the last updates dont what to install and checked the log.

The last successful (64 bit) update KB890830 “Malicious software removal tool x 64” was on 16/8/2012. The next update was “security update KB2589322 for 32 bit system. It was successful !! and so was a couple other following 32 bit updates. But then the next 64 bit updates failed. See attached.
And now my system cannot install updates. How can a 32 bit patch be automatically updating a 64 bit system? And how do I fix it? Please help.

Looks like that update is for Office and the 32 bit version. If you did not install the 64 bit version, the update is correct.

If you want to check, right click the white flag and open Windows Update. On bottom left, select Installed Updates and check the Office section.
