ITunes 10.5 has an invalid signature, it will not install

I was trying to update my iphone 4 but it says a new itunes to 10.5 should be installed first.  But when I hit the download itunes it says it has an invalid signature and will not be installed (These includes the shared files, Quick Time and Safari). Therefore, I can not update my iphone4. What should I do?

Please check this post out. I think you should be able to resolve your update process!

  • Error "itunes has an invalid signature". Will not install. Why?

    Every time I try to update iTunes on my desktop computer I keep getting the same error message "iTunes has an invalid signature. Will not install. Why am I getting this message? and how can I fix it.
    ITunes came with the new HP I purchased in 12/2013. I have had a problem only with updates. I thought about uninstalling on my desktop but do not want to lose my songs. Was hoping to find a better solution than uninstalling and then re-installing.
    Any how would be appreciated.

    The error suggests some sort of corruption with the file you downloaded. Clear your browser's cache and download a fresh copy of the iTunes setup file.

    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
    If you are running 64-bit Windows and the above steps haven't helped try installing the version of iTunes that can be downloaded from this support document. iTunes 12.1 for Windows (64-bit — for older video cards)

  • Trying to upgrade itunes on windows computer error comes up invalid signature and will not install, trying to upgrade itunes on windows computer error comes up invalid signature and will not install

    invalid signature error when trying to install itunes 12.01? 

    Praise God - I found the solution after hours of work: (1) Uninstall all Apple programs (itunes, Quicktime, Bonjour, .....); (2) Go to "Common Files" and delete all Apple files - this might be difficult for some are locked from you - you may have to change the "Owner" of the file in order to delete it - if that doesn't work "Rename the Apple Follder to something like Apple Old - that's like deleting it.  Then download 10.5 from Apple and away you go - yippee.

  • While downloading the newest version, I receive an error saying itunes has a invalid signature and wil not download. Help!!!!!!

    When downloading the newest version, I get an error message saying iTunes has an invalid signature and will not be downloaded.  Help!!!!!

    Thank you for using the Apple Support Communities
    I am assuming you are having difficulties installing the latest version of iTunes. Are you using a Windows PC or a Macintosh? Which version of Windows or OS X are you using?

  • 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.
    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've been trying to install itunes on windows 7 but apple mobile device will not install

    I've finally managed to narrow the problem down to the following file:
    C:\Users\xxxxx\AppData\Local\Temp\Rar$DIa0.119\AppleMobileDeviceSupport64.msi: The archive is corrupt
    this is the file delivered with itunes and it's definitely causing the problem because when I try to install one I downloaded from
    http://www.javakrypt.com/itunes/
    it installed ok, however when I try to run itunes the amd driver is installed the ipod connects but itunes has a version issue with the AMD driver and asks for a reinstallation of itunes.
    My question to apple is where can I download an incorrupted AppleMobileDeviceSupport64.msi file for the latest release of itunes, and can you pleas everify that the version you are deploying with the current version is not corrupted.(The first file I see when I extract the MSI file has a random character file name with no modified date and a size of 16640. WInrar refuses to extract any files from the msi file.
    I believe many people are having this problem and if they can get this file it may their problem as well.

    OK I've fixed the problem and my thanks go to redmars.com.au (link below plus copy of solution)
    http://www.redmars.com.au/blog/itsupport/327
    To summarise what I did I
    0. the pnputil -e uninstallation didn't work for me so 
    1. modified the permissions on the C:\Windows\System32\DriverStore\FileRepository\netaapl64.inf_amd64_neutral_hexidecidforyourcomputer folder so that I could access it
    2. I deleted the files in this folder
    3. Retried the install from command line with log file enabled but it still rolled back, but in the log file I noted it wasn't finding the netaapI64 files and when I checked the above folder these files were missing.
    4. I tried copying the files from the msi file using winrar but this failed passing a file corrupted error message and files copied had a zero byte size (i.e. empty)
    5. I copied the files from a friends folder who didn't have this problem files are (netaapI64.cat, netaapI64.inf, netaapI64.PNF, netaapI64.sys and wdfcoinstaller01009.dll)
    6. retried the install from the command line and it worked. Started itunes connected itouch, it installed the drivers and the itouch appeared in itunes.
    I can now access my ipod from itunes.
    The only problem now you face now is how to get the uncorrupted files detailed above. Does anyone have a solution to this? Winrar states files are corrupted. but they obviously aren't otherwis ethe installation wouldn't work.
    text for solution here follows :
    I recently came across a problem on a Windows 7 64bit laptop where Apple's iTunes was failing to recognise a connected iPhone. It was giving a error that the wrong version of iTunes was installed and I should install the 64bit version of iTunes. As I had no idea how what had been performed up until this point I performed a full uninstall of iTunes. I then downloaded the latest version of iTunes 10.5.1 and ran through the installer. At one point during the install I noticed the install gave the message 'Rolling back action' and thought to myself this cannot be good.
    At the end iTunes indicated it had a problem installing and I should try again. The weird thing is if you didn't pay attention to the message you could quite easily click on ok and iTunes will work except it'll fail to recognise any iPod, iPhone or iPad device. To help identify what actually failed to install I checked the windows services management console and found the Apple Mobile Device Service was missing. This makes sense because it's that service which communicates with the iPhone. The question is why was the Apple Mobile Device Service (AMDS) failing to install?
    To find out I needed to capture a log file of the install process. A bit of research helped me identify that the iTunes64Setup.exe contained 5 separate windows installer files:
    AppleApplicationSupport.msi
    AppleMobileDeviceSupport64.msi
    AppleSoftwareUpdate.msi
    Bonjour64.msi
    iTunes64.msi
    I needed to extract AppleMobileDeviceSupport64.msi from iTunes64Setup.exe so I could generate a install log. The solution is to install WinRAR which you can download here http://rarlab.com/download.htm. After extracting AppleMobileDeviceSupport64.msi to c:\temp (you can use any folder you like here) I opened a command prompt and issued these commands:
    cd c:\temp
    msiexec -i AppleMobileDeviceSupport64.msi -log AMDS.log
    This will attempt to install the AMDS and generate an installation log c:\temp\AMDS.log. Looking through the log I found the install failed because the format of C:\Windows\System32\DriverStore\FileRepository\netaapl64.inf_amd64_neutral_dc2c bd989eec1514\netaapl64.inf was invalid. I opened the file in question and found it to be completely blank. I coulnd't just delete the files in question because they are protected by the Windows operating system, and anyway the correct method to remove a driver package from the driver store is to use the pnputil.exe tool. However if the driver package didn't complete installation in the first place then it may not work, but it was always worth a try.
    To use pnputil I needed to run a command prompt as an administrator. I Clicked Start, All Programs, and Accessories, then right-click Command Prompt, and then click Run as Administrator. From the command prompt type I typed in pnputil.exe -e. This produced a list of installed driver packages. Looking through the list I was looking for something like this:
    Published name :            oem30.inf  Driver package provider :   Apple  Class :                     Network adapters  Driver date and version :   07/12/2011 1.8.4.2  Signer name :               Microsoft Windows Hardware Compatibility Publisher
    This is the Apple network adapter driver. The important information here is the Published name oem30.inf. To uninstall the driver use the command pnputil -d oem30.inf (replace oem30.inf with the correct published name for your PC). After this try and the install again: msiexec -i AppleMobileDeviceSupport64.msi -log AMDS.log. If this fails or as in my case the driver package doesn't show in the list of installed drivers you'll need to take more drastic (and potentially dangerous to your PC's health!) measures.
    By default the files in the driver repository are read only and can only be modified by the Windows Operating System, and this is for a good reason. I needed to change the permissions on the driver package so I could delete the corrupt files. Caution proceed at your own risk, make a mistake here and your computer may stop working and a system restore or rebuild may be required.
    The first thing I needed to do was to take ownership of the folder so I could change the permissions. From windows explorer I clicked on Folder and search options under the organize button. Next I clicked the view tab and clicked on Show hidden files, folders, and drives. By unticking hide extensions for known file types and unticking Hide protected operating system files I was able to view the files I needed to remove. From the windows explorer window I browsed to browse to C:\Windows\System32\DriverStore\FileRepository\, which was now visible and right clicked the netaapl64.inf_amd64_neutral_dc2cbd989eec1514 folder and selected properties. I clicked the security tab and then the Advanced button. Under Advanced I clicked the Owner tab and then clicked the Edit button. From the change owner to: box I selected my username, and then ticked Replace owner on subcontainers and objects and clicked OK to set the changes.
    Next I gave myself Full Control to the folder and files. Back on the Security tab I clicked the Edit button, and with Everyone highlighted in the Groups or user names I ticked full control in the Allow column. I clicked OK and accepted the warning message Windows presents about security and access problems. At this point I could delete the contents of the netaapl64.inf_amd64_neutral_dc2cbd989eec1514 folder.
    I tried re-installing the Apple Mobile Device Service (AMDS) using msiexec -i AppleMobileDeviceSupport64.msi -log AMDS.log command and I no longer got the Rolling back action error. All that I had left to do now was install iTunes again and the iPhone was now recognized when I connected it to the PC.

    I am trying to update my iTunes on my PC and I keep getting this message after I click the button to install the update ... "Apple Software Update for Windows" has an invalid signature and will not install
    Okay. Rather than using Apple Software Update, let's try updating your iTunes using an installer downloaded from the following location:
    Latest iTunes Installer
    Does the install using the iTunesSetup.exe from there go through any better? If not, what error message do you get from that?

  • 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??

    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?

  • 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.)

  • I run Windows 7 and the newest version (10.6) of iTunes will not install. The installer won't even begin, and when I run the Apple Software update, it tells me that iCloud and iTunes have invalid signature.

    When I run the Apple Software update, it tells me that iCloud and iTunes have invalid signature and will not be downloaded. When I DL iTunes64setup.exe, the program will not start (there's a bar that flashes but nothing actually begins). I've done everything short of reinstalling Windows to fix this (system resore, unistalling all Apple products, taking down firewall, running Windows FixIt - which either won't find the problem or gives me an error saying that the troubleshooter cannot be downloaded at this time, going into the security features to allow programs without valid signatures, trying to install earlier versions of iTunes). It all started when I downloaded the Decemberists new album on my iPhone, and it wasn't downloading it properly so I connected it to my Dell, but some songs still wouldn't DL - also, the newest OS for my iPhone still won't install via WiFi - and so I uninstalled iTunes first, but nothing is helping. And I don't have any security issues (Norton has checked). Any ideas? I'm at my wit's end after 3 days of this. Thank you.

    Ok, so after like 4 days of going through all these different issues, I figured out that several programs weren't downloading, and it was an issue with my wireless connectivity messing up the digital signatures, so if you plug in your comp to the modem and delete your temp files, it should start to work!

  • 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.
