Keep trying to install update for itunes and keep getting 'invalid signature'

keep trying to install the new updates for itunes and keep getting 'invalid signature' and it won't download

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?

  • I have been trying to install the new iTunes, and i get an error that a program could not be run.

    I have an old version of iTunes and require the new version to connect my IPod. A program can not be run and the installation stops. I have no idea what program or what is required to run it. Please Help.

    That would be my first guess.  You might be trying to install the 32 bit version of the program.
    Update the thread with more info on your apple software etc if its a 64 bit install you're trying to perform.

  • HT1926 I am trying to install the latest itunes, and I get the error, unable access C:\ProgramData\34BE82C4-E596-4e99-A191-52C6199EBF69\GEARIFix.exe. I can access this dir via explorer but there is no such .exe.

    I am using Windows 7 and had to deinstall iTunes as it failed on a previous instal. i was told to update my iphone to iOS 6 so that I could get the iOS 6 supporting version of itunes.
    I have followed the FAQ to resolve install issues and have no apple software installed on my machine
    During install I get a dilog box open, with a retry and cancel buttons with the notice that the iTunes install cannot access the following file:
    C:\ProgramData\34BE82C4-E596-4e99-A191-52C6199EBF69\GEARIFix.exe
    In Windows Explorer I can open that directory, but that .exe is not present. iTunes installer thinks its locked
    the files present are
    Folder - x64
    DIFxAPI.dll
    DifXInst64
    GEARAspi.dll
    GEARAspi64.dll

    C:\ProgramData\34BE82C4-E596-4e99-A191-52C6199EBF69\GEARIFix.exe.     Verify that you have access to that directory. Retry or Cancel?
    Opening Windows explorer with hidden folders and files showing, I can access this directory. it contains 1 folder

    I have tried all the steps to completely remove Apple software from my system as set-out in the FAQs.
    I cannot delete the Temp directory as there is one file
    FXSAPIDebugLogFile
    Where I get the file-in-use-error

  • I am unable to install the newest update for itunes and quicktime because of a bonjour error about path not being located

    I have windows 7 and I have been trying to install the newest update for itunes and quicktime but I keep receiving the same Bonjour error. I even tried to do it manually and no luck. I also tried to unistall bonjour but it would not even allow me to unistall it either. No matter what I do I get the same error listed below:
    The path C:\users\owner\appdata\local\apple\apple software update\bonjour64.msi cannot be found. verify that you have access to this location and try again or try to find the installation package "bonjour64.msi" in a folder from which you can install the product bonjour.
    I would greatly appreciate any help because this appears whether i am trying to install the updates or remove bonjour to reinstall. I am stuck.
    Thank You in advance!!!

    Unfortunately, this sort of trouble has gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on 25 June 2010. First we have to find a copy of the utility.
    Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. (The results from mydigitallife and Major Geeks are worth checking.)
    After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
    If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
    Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove".
    Quit out of CleanUp. Restart the PC, and try another iTunes install. Does it go through properly this time?

    Hey schouten53,
    Thanks for the question. I understand you are experiencing issues with the latest iTunes update. Let’s troubleshoot the iTunes installation by completely removing and reinstalling iTunes and all related components (it is important to remove all components in the order listed).

  • Hi i'm trying to install updates but Name and then the password I have for the account won't let me in. Is my name my email address?

    hi i'm trying to install updates but Name and then the password I have for the account won't let me in. Is my name my email address?

    Updates do not normally require any kind of password access.  It is more likely your machine's security is asking for you to allow things to be updated.

  • I download latest software update for itunes and iphone. they successfully download, but then a message comes up saying unable to install as file has been corrupted. what is the cause?

    I download latest updates for itunes and my iphone, when it comes to installing, it successfully downloads, but then i get a message for iphone software error=1403 file corrupted, and for itunes it downloads, then when i try to install it a message says unable to install software, file maybe corrupted!! 

    The iTunes update must be downloaded and installed before you try and use it to update the iPhone OS
    Download iTunes 10.2.2 from here: http://support.apple.com/kb/DL1103
    When it completes it will auto mount the disc image and show you the package installer, don't try and do anything with the file until it gets to this stage.
    Once that's installed reboot the Mac, run iTunes, connect your iPhone and let it sync, then hit the update button and let it complete that step by itself (which will require a restart of the iPhone)

    i just downloaded the new update for itunes and the itunes store wont open up it is taking a long time it still hasnt loaded since 5pm, i also cant sighn in either it just keeps on saying accessing itunes....

    Close your iTunes,
    Go to command Prompt -
    (Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
    (Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
    In the "Command Prompt" screen, type in
    netsh winsock reset
    Hit "ENTER" key
    Restart your computer.
    If you do get a prompt after restart windows to remap LSP, just click NO.
    Now launch your iTunes and see if it is working now.
    If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:
