Solved: Need to install past security updates?

I just completed a Win 7 update today and noticed in the update history that there are two security updates that failed to install about 10 months ago (when I bought this computer). All other updates have installed fine. Do I need to try to install either of these updates, or would subsequent updates have me covered? The two updates that failed to install are:

Cumulative Security Update for Internet Explorer 9 for Windows 7 for x64-based Systems (KB2870699)
Installation date: ‎9/‎28/‎2013 2:10 PM
Installation status: Failed
Error details: Code 80242016
Update type: Important

Update for Windows 7 for x64-based Systems (KB2834140)
Installation date: ‎9/‎28/‎2013 1:28 PM
Installation status: Failed
Error details: Code 80242016
Update type: Recommended

Appreciate any advice!
