HT201413 Invalid signature when updating itunes and icloud, cancels update?

Apple software update cancels because of invalid signatures, what setting do I need to change?

That one suggests the installer has gotten 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?

  • Porblem: 3Gs not recognised AT ALL after updating itunes and trying to update phone

    Have updated itunes and tried to update Iphone 3gs.  Now I have connect to itunes display on iphone, and when I connect, I get "new hardware not recognized", "iphone in recovery mode", and device does not come up in itunes.  In device manager "?!" are shown in "other devices" next to "iphone in recover mode".
    Any ideas?  I've been trying all day to fix this.
    Currrently when I plug in the Iphone, the computer completely ignores it and no reaction, so seems to have got a bit worse!
    I'm using PC, Win XP SP2.
    I've tried all my USB ports, and various fixes I've found online, but happy to keep trying them if you have any ideas???!?!!?!
    At the moment my iphone is dead/blank/part restored, so can't do any solutions that require the functions of the phone.

    Thanks wjosten.  I've now been through all this, and there was a lot of old 3d party phone stuff to remove.
    However, I have not progressed really.  Any other thoughts on this please?

  • My iphone 3gs wont update. itunes and ipod touch update no problem, my GF has exact same phone and hers updated also...any advice?

    My iphone 3gs wont update. itunes and ipod touch update no problem, my GF has exact same phone and hers updated also...any advice?

    If I was in your shoes, I would choose to restore the iPhone with iTunes and then choose to NOT restore a previous backup.  I'd then go on to set up the phone as though it were totally new, and choose the stuff to load onto it.
    The reason I'd go through that trouble.. even though it meant losing a lot of settings and having to set stuff up again .. is because I wasn't sure I could trust the backup that it's restoring from.
    If you have trouble again after doing the fresh reload -- especially if it's soon after you do it -- you may have a hardware issue with the phone, such as faulty flash memory or a processor chip that's failing. If that's the case, you'll want to consider your repair/replacement options at that point.

  • ITunes and iCloud not Updating

    As of Yesterday afternoon my iCloud will not update my information. I called the apple help line were they took me though many steps that I had already done and finally said that the server must be down and to try to sign in to iCloud later. This is funn because he had mentioned earlier that the servers were fine. I also noticed that I can not update any of my apps on iTunes from my Macbook or iOS devices.
    I am not sure were to go from here. The call didn't help and I know that my network is working fine. I haven't done anything differently then usual on my mac.
    I always update everything and keep everything clean. I am running the latest updates for OSX and iOS.
    Can someone help?

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

    good luck!

    Hi Rick,
    by "repair" I mean I went to the control panel, option - programs and features, and in the list of all my installed programs I selected "Apple Software Update". On top of the screen you find the options Uinstall, Change and Repair. I clicked the repair button and that did the trick. After the repair I could uninstall the program. I also uninstalled iTunes, Apple Application Support, Apple Mobile Device Support en Bonjour, thus all Apple programs. Then I installed iTunes 10.5 again and everything went fine.
    Success,
    Peter

    Go directly to Apple link to download

    Select "Save" instead of "Run". Once downloaded, double click the iTunessetup.exe or iTunessetup64.exe to install.

  • Trying to update iTunes and i get an error message saying something about "invalid signature". Help?

    Trying to update iTunes and i get an error message saying something about "invalid signature". Help?

    " The feature you are trying to use is on a network resource that is unavailable. I tried to uninstall iTunes, and it would not uninstall. It gave me the following message " The path C:\documents and settings\network service\local settings\application data\apple\apple software update\iTunes.msi cannot be found.
    Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    To install the utility, doubleclick the msicuu2.exe file you downloaded.
    Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

  • When did Apple turn into piece of ****?  It prompted me to update itunes and install icloud. I did. It crashed saying it was not properly installed and reinstall it. Since then I have been trying. I worry if my thousands of dollars worth of music is lost

    When did Apple turn into piece of ****?  It prompted me to update itunes and install icloud. I did. It crashed saying it was not properly installed and reinstall it. Since then I have been trying. I worry if my thousands of dollars worth of music is lost

    I had a very similar problem, error 4251.  (look in your log you will see that error)  Since I finally fixed my problem, I thought I would see if I can help someone else.
    What I found is that I lost burn ability in both iTunes AND Windows.  Like you did.  I did some digging and found that this wasn't hardware related at all.  In fact, this boils down to a registry key getting messed up.  (sigh) Yeah.  It causes the system to get a bad 'handle'.
    OK, here's what to try.  Go to this Microsoft KB article.  Scroll down and find the *manual* instructions for Vista.  Delete the registry key that it specifies.  Reboot. Now verify that you can burn in Windows.  (If you have a RW disc, do a disc erase, or just try and burn from Windows Media Player.)  If that is working now,  you're on the right track.
    Now the issue is that iTunes will still be broken.  Go and install the latest Gear driver.  (I know you may have done it, but do it again.)  Now follow the intructions in this Apple KB article to verify the "GEARAspiWDM" info is back there in the registry.  Now reboot.  Try and burn in iTunes. 
    I hope this helps.

    I just tested it (on 10.6.8) and it worked perfectly well, so it may be something on your computer. You could try creating a new user account on your Mac and using that to try downloading. You can then install on that account and it will be available on your normal one.
