Error 0x80240016 downloading definition updates


  • I came in this morning to the nice orange icon in my tray telling me I needed to download definition updates. When I click on "Check for Updates Now" I get "Error found: Code 0x802400016."

    What do I need to do to download the updates?

  • Hello Jenifer,


    Thanks for your post.  Error 0x80240016 is



     Operation tried to install while another installation was in progress or the system was pending a mandatory restart.



    I believe you simply have a reboot pending for this machine.  After doing so you should be able to download definition updates if you are either talking to a WSUS/Distribution server or opted into MicrosoftUpdate.

  • Thanks for your postings,


    Just to be clear, I was only advocating the reboot for the exact error number: 0x80240016.  Other error numbers would like require other troubleshooting steps.


    Teresa & sonnes: can you post the exact error number you were receiving, is it the same?  Also, has the definition update process ever worked on this machine?

  • yes the error no is the same that is why I posted and yes it has worked on this machine.


    My computer has two drivers C and D.  The C drive is the smaller of the two.  Could it be this that causes the problem and if so how can I cure it to make the updates go on the D drive?  It is a Sony lap top PCG-GRT240G

  • I reinstalled Windows Defender today and when trying to get updates, got the 0x8020016 message.  Have cold booted twice to no avail.  Any other suggestions?

  • Hi!

    By the way, did you ever figure out what the problem is with the 80070714 code?  That's what I keep getting when I try to update Windows Defender, and I can't find an answer anywhere on the Microsoft website.

  • did you ever try to manualy update your client using windows update ?

  • "did you ever try to manualy update your client using windows update ?"

    Does simply running Windows Update count as manually updating my client?  I run the update periodically and the only update that always fails is the one for Windows Defender.

  • Hi folks

    As Craig mentioned earlier in the posting, this forum focuses on Forefront Client Security - for help on Windows Defender, I'd recommend posting in the forum Craig linked to

  • Disabling PC Tools Spyware Doctor OnGuard solved my problem allowed me to install the update.

  • I was having the same problem, but mine was a simple solution, I had just done a windows update and it was blocking me. Once I rebooted my Windows Defender Updated just fine.

  •  hey,
    i had exactly the same problem.  I went to this site: http://www.microsoft.com/security/portal/ADL.aspx.  I downloaded the latest version of defender and it worked!

  • This is for those of you using Forefront Client Security: 

    Make sure you have enabled Microsoft Update, not just Windows Update!!
    We have Forefront without MOM support installed on our client image. We had the yellow exclamation system tray icon on all our laptops. Its pretty disappointing, but apparently Forefront requires having Microsoft Update in order to get its definition updates!!!!
    After you get Microsoft Update, open Forefront and click 'Check for Updates' one more time.  It should work properly and give you a nice green check in the system tray ;)

    To enable Microsoft Update:

    For XP: On the client, go to http://update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-US and accept whever agreements needed to get Microsoft Update.

    For Vista: Open Windows Update. Notice in the middle of the window it says "You receive updates:" If this says "For Windows Only," click the yellow boxed link which says something like "get updates for more products." Accept the agreement and you'll apply Microsoft Update.

    If it says "For Windows and other products from Microsoft Update," you have already applied Microsoft Update.

  • Please visit this page on microsoft website. It is realy helpful to fix this error.

  • Boy oh boy, I gotta tell ya', the more I read on pretty much any site or forum about trying to resolve ANY problems with Forefront the more it is very apparent that Forefront is unnecessarily complicated and NOBODY involved with it has any idea how to run or troubleshoot it.

    Very disappointing.

  • I had the same forefront error code 0x80240016 update issue. I realize I had Spybot search $ destroy running. Once I uninstall this I was able to update new definitions for Forefront. I believe you need to uninstall all other anti-spyware program to run Forefront fully. Hope this help someone else's problem
