Windows 7 error “key not valid for use in specified state”

When you see that error upon trying to install or upgrade something on your Windows 7 64-bit machine, chances are that it is caused by a Windows Security update that you need to uninstall. There is probably no point in messing around with the registry or the application that you want to upgrade. Instead, remove the Windows update KB2918614 like this:

Open the control panel, then click  Windows Update

Windows 7 control panelClick Update History and then Installed Updates:

Update HistoryScroll down to Microsoft Windows and look for KB2918614 (I have removed it already before I took the screenshot):

Uninstall KB2918614Finally, hide that update so you don’t get it installed later on again:

Hide KB2918614I’m using a corporate notebook with automatic Windows security updates coming from time to time and encountered that problem while trying to upgrade VirtualBox to version 4.3.12. It is not a VirtualBox issue, though, other installs or upgrades may fail for the same reason. For me, this was a serious problem, because I rely on virtual machines for many demonstrations. Kudos to the forums! They helped me resolve that problem within a day. Thank you once again, guys! 🙂

    Cheers !!

    Thank you SOOOOOO very much. Worked like a charm. I let my computer guys know too! AND they thought they knew everything! But there is still a problem with the HP Print and Scan Doctor 4.4 telling me that my HP Officejet Pro N911a printer has a driver conflict, BUT it prints just fine NOW that I got the software installed with your help. BUT the scanner in the 4.4 program tells me that there is a driver error and to disconnect the printer while on, plug it back in, and restart the computer. That doesn’t change a thing. I STILL can’t scan from my printer to the computer–not with flat bed or the docu feed on top. I don’t know what to do next.

    Ohw man, my hero! i had several other applications that failed to install. Did you reported this to Microsoft as well? Such security update is a serious flaw.

    Hi I’ve tried to download java 3000000 times now and I’m at my wits end! I need to use it for the interactive blackboard for my uni course which has already started!

    I completely uninstalled Java on the add/removed programmes page.

    Since I have tried to download java install from the website both on and offline. I have turned my AV and firewall off! I followed your instructions and couldn’t restart my lap top! Had to start up repair for ages…! Finally got it back up and running and I noticed my Microsoft windows is not (295) it is (309)

    Is that why my windows crashed? Please help! To boot my lap top is in Spanish! I’m English but lived abroad and totally forgot buying a laptop over there would be cheaper but not in my native language! So I’m translating everything either for my self or in order to try and get help!

    unintalled the Microsoft security update still can not install Java Key not valid for use in specified state

  16. #16 by Sylvio Deutsch on September 16, 2014 - 07:21

    It works also for win7 32 bits.

    Thanks for the tip, invaluable!

  17. #17 by Rakesh Kumar on September 16, 2014 - 11:47

    Wonderful solution to an otherwise insoluble problem! My sons bought me a Fitbit Flex as a present and I successfully installed the software on my Mac, but nothing would make it work on my Win7 32-bit machine — until I found your solution. MUCH appreciated!!

  18. #18 by JoeC on September 16, 2014 - 18:06

    This fixed my problem. Thank you!

    I also spent hours trying to reinstall itunes with this repeating error: ” key not valid for use in specified state ”

    Here is what finally worked.

    1. Open control panel

    2. Open Programs and Features.

    3.Click itunes

    4 Click Change

    5 Click Repair.

    Let me know if you also get success.

  20. #20 by Ernie on September 17, 2014 - 14:05

    Awesome!! I’ve been trying to repair my problem for 2 Days. I checked for any registry errors, uninstalled and downloaded and reinstalled the Visual Studio C++ 2008 SP1 as well as Visual Studio C++ 2005 SP1, however because my machine had been altered by the KB2918614 update it wouldn’t reinstall them either. And, when trying to reinstall it kept on reflecting the “Key not valid…..” message. So, you’re advice to uninstall KB2918614 is much appreciated as my machine is once again doing what it’s supposed to do.

  21. #21 by Pablo on September 18, 2014 - 01:57

    Continue to have the “key not valid” after uninstalling the prescribed update. Any suggestions?

  22. #22 by atlcomputerrepair on September 18, 2014 - 11:51

    This was driving me crazy! Thanks!

  23. #23 by Carl Fuglein on September 18, 2014 - 20:00

    God bless you sir. This has fixed a lot of problems for me installing a new computer.

    Thank you so much for your help with my Windows 7 error “key not valid for use in specified state”. I spent hours trying to reinstall Skype which had inadvertently “disappeared” from my computer. Your suggestion, so simple and elegant, rectified the problem. I really appreciate your assistance.

    I got that error trying to download Google’s Sketchup Make. Thank you so very much for the solution! Worked brilliantly!

  30. #30 by xXMrSkyXx on September 21, 2014 - 12:28

    Thank you, for the advice. I’ve been trying to fix this error for a while now. I tried anti-malware, and virus scans off the wall. Then tried messing around with the keys and registries themselves… Neither worked. Then suddenly I tried this, and it worked! Grade-A fix, I will say.

  31. #31 by sou on September 23, 2014 - 12:17

    there’s thousands of updates… how do I find it?>

  32. #32 by on September 24, 2014 - 02:15

    This worked great. Really appreciate the fix. Saved me a ton of time looking for the resolution.

  33. #33 by Sriraj on September 25, 2014 - 10:43

    Try this if it works..

    NOTE : You might need to enable the view hidden folder and files option

    Windows 8 computers

    Go to C:\ProgramData\Microsoft\ “Crypto”

    Windows 7

    Goto C:\AppData\Microsoft\

    Here you should see a folder named as “Crypto”

    Either delete it right away or cut and paste on desktop and then delete.

    Try installing again….

    This should work

  34. #34 by Andreas on September 25, 2014 - 18:04

    I rebuilt a laptop and used the Windows easy transfer program to a new laptop. When I tried to install software such as Java, where I first noticed the error, and obviously after this Microsoft update installed, I could not install anything until I removed this KB update. Thanks for your help

  35. #35 by Celso on September 26, 2014 - 00:34

    Thank you, man. This advice has helped me to reinstall the skype and others softwares after several unsuccessful attempts. I was looking for the solution since Aug in brazilian foruns, but nothing because I was searching the message in portuguese only: It is displayed translated to portuguese here. Now I intend to help some users to solve that here. Best Regards. Celso

  36. #36 by Nelly on September 28, 2014 - 03:33

    very,very helpful, but I didn’t “hide” the offending update the first time and had to uninstall it again in order to install some other software. So, can you explain how to hide this naughty update, for ever? Many thanks…

  37. #37 by Crystal on September 28, 2014 - 04:48

    Thank you!!! !!!!!!This was a big help (after I spent a hours working on what I thought was an iTunes issue)!

  51. #51 by pclark716 on October 31, 2014 - 13:39

    Worked with Vista too! Had been having trouble updating iTunes and Skype – getting that “key not valid for use in specified state” error. Completely uninstalled both and still got the error when I tried to reinstall them. Ran a MS fix that supposedly repaired any registry problems and still couldn’t install iTunes or Skype. Found the Security Update KB2918614 – dated 8/16/2014. Uninstalled it and then tried again to install iTunes and Skype. Success! Thank you!

  52. #52 by MitchT on November 6, 2014 - 04:32

    OMG this is the only thing that worked! I’ve been trying to get rid of the “key not valid for use in specified state” PhysX error for over two months, for two games:
    -Medal of Honor
    -Mafia II

    Dude, or more accurately, Uwe Hesse – Lord Master of Gods, how did you even find this!!!

    I’m not worthy,

    Thank you so much. That error message prevented me from downloading quite a bit of stuff. I would make repeated attempts searching for a solution and then giving up. Finally came across your webpage which was simple, easy to follow and most importantly resolved a pain in my backside. Again Thanks!
