Security Update (QuickTime 7.1.6) has an invalid signature. Not installed.

I installed QuickTime 7.1.6 on XP Pro SP2. I chose the option to make it available to All Users. I am now logging in on the same account that I used to perform the installation. That account is an Administrator account.
When Apple Update runs on my new QuickTime installation, it says a Security Update is available, plus iTunes. I uncheck iTunes and proceed with the security update. It gives me this error message:
Security Update (QuickTime 7.1.6) has an invalid signature. It will not be installed.
I tried Tools > Download Only and it fails with this message:
Security Update (QuickTime 7.1.6) has an invalid signature. The download has been removed.
I tried manually downloading the security update directly from the Apple site. I get the full download no problem. When I run the msi package, I get this message:
The system administrator has set policies to prevent this isntallation.
Reading posts on this forum, I looked at registry keys and permissions. The HKLM\SOFTWARE\Classes\QuickTime.QuickTime key owner was Administrators. The owner of the QuickTime keys under HKLM\SOFTWARE\Apple Computer, Inc.\QuickTime is Kevin (me, also an Administrator). I modified QuickTime.QuickTime so Kevin is the owner, made sure it trickled down to all subkeys, and the problem persists. No change in behavior.
What do I do now?

What was this "other" update that installed sucessfully? I noticed that you are still using OS10.4.7.
Did you repair permissions prior & after the installation? If not, suggest that you do so & try to install QT again. Make sure you repair permissions after the installation.

    Please help...need to get newest update so I can activate my new IPhone4. Thanks

    That suggests that the installer is getting damaged during the download.
    I'd first try downloading an installer from the Apple website using a different web browser:
    http://www.apple.com/itunes/download/
    If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

  • Apple Software Update for Windows (2.1) has an invalid signature

    When I run ASU and it wants to install ASU 2.1 I get the error that it has an invalid signature. It was suggested to use Tools and first download it and then install it, but I manage 350 computers and am trying to automate some of this.
    Does any one have a suggestion?
    I wonder if Apple will issue a patch, or if there is some amiss with my current ASU.
    Jane

    Thanks for the replies, but what I am hoping for is a solution.
    Even though I asked, you never said if you have an ASU 2.0.0.21 ... so this solution runs the risk of being irrelevant to your situation. (It applies to the issue of ASU 2.0.0.21 on an XP PC returning an "invalid signature" message when trying to download an ASU 2.1.0.101.)
    If that's what you've got here, then usually a software installer bundle from Apple which contains a higher version of ASU than the 2.0.0.21 will install on the PC in question.
    (Avoid using the BonJour for Windows 1.0.4 standalone installer just at the moment, as a precaution. Last time I checked, about 20 minutes ago, that still contained an ASU 2.0.0.21, and that won't get you any further forward than you currently are ... assuming that you've currently got an ASU 2.0.0.21 in place.)
    So download and install another Apple installer bundle. Here's a link through to the QuickTime Standalone installer, although the Safari for Windows or iTunes installer would also work:
    Latest Quicktime Installers … get the one that doesn’t mention iTunes
    That should, as part of the install, update your ASU to version 2.1.0.101. To check on that, launch ASU ("Start > All Programs > Apple Software Update"), go "Help > About Apple Software Update" and check the version number. If you're now at ASU 2.1.0.101, you're past the problem with ASU 2.0.0.21 returning an 'Invalid signature" message when trying to install an ASU 2.1.0.101 (assuming that's the particular problem you were actually experiencing).
    You can then uninstall QuickTime for Windows (or Safari for Windows, or iTunes and QuickTime and Apple Mobile Device Support, depending on what installer you used to update your ASU version) through your Add/Remove programs control panel.

  • Trying to load a secure website, firefox says "Secure Connection Failed: Peer's certificate has an invalid signature."

    I need to get on this website, which only allows Firefox and Safari for Mac OSX, but since I upgraded to the latest Firefox update, this is the message I get:
    Secure Connection Failed
    An error occurred during a connection to teleserve.dlt.ri.gov.
    Peer's certificate has an invalid signature.
    (Error code: sec_error_bad_signature)
    Help!

    The site doesn't seem to be sending the correct intermediate certificate.
    You can install this VeriSign intermediate certificate that works for me.

  • How to verify Security Update (QuickTime 7.1.6) is installed

    Hi,
    I manually installed Security Update (QuickTime 7.1.6) for Windows but I am not sure how to verify whether the update successfully installed or not. Is there any way we can check that the update is installed? Maybe file version? Hopefully someone can help.
    Thanks,

    If you install QT 7.1.6, it says 7.1.6 in the help screen. If you install the newly released security update, nothing changes to show the security update has been applied. It still says 7.1.6 in the help screen. Even running the patch manually, it gives no indication it has successfully installed.
    I am required to install this patch on about 200 clasroom machines but have no way to verify which ones get the patch and which don't. Apparently I can't even go around to each of them and manually verify.

  • I cannot update  iTunes because when I run the Apple Software Updater, it says "'iTunes   QuickTime' has an invalid signature. It will not be installed." If I try downloading only it says "'iTunes cannot update.  Invalid signature.

    This forum is for questions from those managing sites on iTunes U, Apple's service for colleges and universities to post educational material in the iTunes Store. You'll be most likely to get help with this issue if you ask in the general iTunes for Windows forums.

  • When downloading updates for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed.

    When downloading updated for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed. If I don't get that message I get a message saying that the download was unsuccesful and that in order to download I need to go to tools and then select dowload only. Please help I really want to update my iphone!

    Thanks for helping out, but I already tried these steps.
    I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
    Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
    So, it turns out that a broken battery can cause this behaviour.
    But thanks again

  • I get an error "iTunes + QuickTime" has an invalid signature while updating from 10.1 to 10.2.2

    I get an error "iTunes   QuickTime" has an invalid signature. The download has been removed.  When trying to update from version 10.1 to 10.2.2.  I have a Toshiba laptop running Windows 7 OS.  I have tried repairing all the Apple software on the laptop.  What do I need to do to get this updated?

    I have not had this problem before but the latest update to iTunes + Quicktime, offered today, puts me in the same situation.
    The web is covered with reports of this issue over the years, always "iTunes + Quicktime has an invalid signature", but nothing I can see which is a good fix for the problem.
    Tried chkdisk, install manually doesn't work, the installer just keeps trying.
    Tried installing QT 7.6.4 independently from the Apple download page, that didn't help either.
    If this is so prevalent, why isn't there more on the main Apple site about it?

  • Received notice to update my I Tunes.  Would not update.  Error message read " I Tunes has an invalid signature"  never had an issue with updates till this notice.  What do i do to resolve this error?

    Received notice to update ITunes.  When downloading,  got error message "ITunes has an invalid signature" and would not update.  Never had an update issue until this download.  How do i rectify this error?

    Hi, bro2pro.
    I would recommend a complete uninstall as outlined in the article below.  Make sure to process the uninstall in the order specified. 
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
    http://support.apple.com/kb/ht1925
    Once uninstalled, download iTunes directly from here iTunes 11.0.4 or iTunes.com.  Make sure to save the file to your desktop instead of selecting the run option.  Locate the file on your desktop, right click and select run as administrator.  This should allow the install. 
    Cheers,
    Jason H. 

  • 8.2.1 error message "iTunes + Quicktime" has an invalid signature.

    I am getting this error message when I am trying to download & install the 8.2.1 update. The entire message states "iTunes + Quicktime" has an invalid signature, it will not be installed. I saw another post started by Cfrolich, but it doesn't look like they got the problem fixed. Has anyone had this same error message? Can anyone help??

  • ITunes & Quicktime has an invalid signature. The program has been removed

    When I try to update itunes through the apple software update, i get error message 'itunes and quicktime has an invalid signature. the program has been removed.'
    When I go to download from the apple website.. it downloads 10% and then stops.
    I have tried downloading through google chrome, firefox and IE, I have tried to delete my temp file, And I have also gone into internet options and ticked 'allow software to run or install even if signature is invalid'.
    Nothing is working!!! Does anyone know how to fix this?

    Okay. Try downloading and saving the installer onto a different PC. Copy the iTunesSetup.exe (or iTunes64Setup.exe) onto a USB key or thumb drive or other external drive (or even burn it to a CD) and then carry it to your PC. Copy the installer onto your internal hard drive, and then start the install by doubleclicking the iTunesSetup.exe (or iTunes64Setup.exe).
    (If we can get a working copy of the installer onto a PC, installs will usually go through without the invalid-signature/not-valid-win32/unknown-publisher/etc errors.)

  • When I try to download the latest version of iTunes on my iPod Classic I get the message that "iTunes has an invalid signature" and that "Content was blocked because it was not signed by a valid security certificate.  Anyone know how to fix this?

    When I try to download the latest version of iTunes from apple.com, I get the message "Content was blocked because it was not signed by a valid security certificate."When I open iTunes and try to download the latest version there, I get the message "iTunes has an invalid signature.  The download has been removed."  I have also gotten an Internet Script Error stating that an error has occured in Line 0, Char O and that "Access is denied to images.apple.com/global/scripts/lib/iepngfix.htc."  This problem has never occurred with earlier versions of ITunes.  Anyone know how to fix this problem? 

    Are you downloading iTunes form an Apple website or somewhere else? If the answer is somewhere else, try downloading it from Apple. Click on iTunes in the black menu bar above and go from there.

  • When I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and wont be installed. I use Windows 7.

    Everytime I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and can't be installed?  I have tried to install it two times and get the same message each time. Any solutions to my problem?? Those who have installed ITUNES 11 is it hard to work with? maybe im lucky it wont update?? I don't know.

    That suggests that the installer is getting damaged during the download.
