Auto Downloads always get "Invalid Signature"

There must be someone out there that has an answer to this. It only started happening within the last 6/8 months. I’ve tried the repair to the Apple Updater it doesn’t work for me the idea that it’s something to do with the wifi router can’t be as we have a laptop working ok (using W7)  It can’t just be Explorer as It won’t work with Chrome.  Could it be a Microsoft Problem?  The only way I‘ve managed to download iTunes is direct fom Apple by overriding blocked content and that only works through Explorer.

Try a search for similar issues and possible resolutions.

  • TS3212 when i try to download the latest version of itunes i get invalid signature, what daoes this mean.

    When i try to update my itunes i get invalid signature, what is this and how do i download the latest version?

    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 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.

  • Help with updating to 10.5 from 10.3 and getting "invalid signature" error

    I am trying to update to iTunes 10.5 so I can sync my new iPhone 4s but I keep getting the error message "invalid signature".  I have tried turning off firewall and antivirus as suggested on this forum to no avail.  Also going through Tools, Download only produced the same error.  Any Suggestions?

    I, too, am unable to update to iTunes 10.5 (iPhone 4) OR Safari.  Contunally get "Invalid Signature" messages.  I have "changed" each Apple, iTunes and Safari application through Add/Change Programs to no avail.  I am forwarned removing iTunes from my PC will cause me to lose all my music.  Any suggestions?

  • I keep getting invalid signature when trying to upgrade to 10.5 from 10.4.1.10

    I've tried to install 10.5 numerous times and keep getting "invalid signature" error even after doing the suggested Apple Software Update 'repair' as well as doing the download and running the install manually.
    I now have updates piling up on my iPad2 as I can't sync to install ios5.......................  Not happy!

    Click here and download the software. Unless otherwise noted, a device running iOS 6 requires at least Mac OS X 10.5.8 and iTunes 10.6.3 to be synced from a Mac.

  • STILL GETTING INVALID SIGNATURE WHEN TRYING TO UPDATE ITUNES

    I am still getting invalid signature when trying to update Itunes. I have tried updating manually, but I get the
    same thing, an invalid signature error. I tried updating on another computer in the house and it updated fine!
    That computer was running windows 7. The laptop I'm having problems with is Windows 8. Need Help!!
    THANKS!

    Go directly to Apple link to download
    http://support.apple.com/kb/DL1426
    Select "Save" instead of "Run". Once downloaded, double click the iTunessetup.exe or iTunessetup64.exe to install.

  • Cannot download 10.5 -invalid signature

    Trying to set up my new iphone through itunes but it says I need the new 10.5 version. When I try to download it, it stops halfway through and says 'itunes 10.5 cannot be downloaded due to invalid signature' and then just closes. Help!

    Safari on the iPad can't download anything other than images which you can save.
    iTunes on your iPad consists of 4 apps which are included with the iOS:  iTunes (a portal to the iTunes Music Store), App Store (a portal to the iTunes App store), Music (plays your music), and Videos (plays your videos).
    Reverting back to a prior iOS is not supported.

  • Attempting to install iTunes Version 10.5 and getting Invalid Signature. Can someone please help???

    I am attempting to install iTunes Version 10.5. I am getting the following messages...
    "Files shared by these updates" has an invalid signature. It will not be installed.
    "iTunes" has an invalid signature. It will not be installed.
    "Safari 5" has an invalid signature. It will not be installed.
    I somehow got around this annoying "invalid signature" problem before by installing the iTunes update through the Apple site.
    http://www.apple.com/itunes/download/
    When I tried that, now I get...
    "The installer encountered errors before iTunes could be configured. Errors occurred during installation. Your system has not been modified. Please run the installer again, or click Finish to Exit"
    All this to get the latest iPhone software. And every blessed time I go to Sync my iPhone, I run into iTunes issue on my Dell PC here. I guess PC and Mac just cannot play well together.
    Can someone PLEASE help me out here???
    Thanks in advance for your help.

    Hi. I also had this problem when trying to connect a new iPhone 4S & it needed iTunes 10.5. Went to the Apple website as update section of iTunes was not getting any luck - went to downloads section of Apple website & downloaded the whole iTunes 10.5 program as though I did not have it in the first place (& also downloaded the programs for Quicktime 7.7.1 & Safari 4.0.3) ie not just the upgrades. I created a restore point in my Windows XP in case it all went pear shaped & then went ahead & installed all 3 programs. Opened iTunes at the end & all my music, apps, movies were all still there & now the new iPhone 4S works perfectly with the iTunes. Hope this helps.

    I've had this problem for awhile in Windows XP SP3. Last night, the simplest thing occurred to me...here's what I did (and I'm telling because it worked).
    1. Clicked on Start
    2. Clicked on Control Panel
    3. Chose Add/Remove Programs
    4. Found Apple Software Updater and clicked Remove, then responded Yes
    5. Went to apple.com and clicked on Support, and then Downloads
    6. Downloaded the latest version of Safari ONLY
    7. Installed Safari (knowing it would install the latest version of Apple Software Update)
    8. AFTER the installation was complete, I clicked again on Start, then All Programs
    9. then, clicked on Apple Software Update

  • DESKTOP SOFTWARE DOWNLOAD ALWAYS GETTING INTERRUPTE​D

    Hello,
    I just acquired a Blackberry Torch 9860 and have been trying to download the desktop software to no avail.
    The download is always getting interupted with the following message "710_b042_multilanguage.exe download was interrupted. This program is not commonly downloaded and could harm your computer" When I click Resume a SmartSreen Filter Internet Explorer window opens with the message that "this program might harm your computer." When I press Run Anyway another window called 16 Bit MS-DOS Subsystem opens with a message that "The NTVDM CPU has encountered an illegal instruction.....chose to terminate the application.
    Please, help.

    Hi and Welcome to the Community!
    It sounds like you have a computer problem, not a BB problem. Maybe you have some virus protection on your computer blocking this? Maybe something else? It's a basic function...downloading files to your computer. Something on your computer is blocking this from happening, but digging into that needs a computer expert, not a BB expert.
    Good luck!

  • Cannot change the print margins when printing out my spreadsheet.  Tried clicking on format and then Document but when I enter a number I always get " invalid number".

         I cannot change the margins when printing out my spreadsheet.  I clicked on the format then on document and got a entry box.  But everytime I try entering a number to change the left margin ( tried .5 ) I get an " invalid number " response.  I can print out the spreadsheet but always get a message telling me the margins may be too small and data may be clipped.  Data doesn't get clipped but left part of the spreadsheet is right at the left side of the paper.  Want to change the margin so I don't get that message.

    Naming the spreadsheet app would do wonders for getting an answer.

  • ITunes upgrade won't download due to 'invalid signature'

    I have a 2nd Generation iPod Touch which will not download any iTunes software upgrades when prompted to do so.  The first error message advised me to go to Tools, then Download Only (which I did).  The next error message said that iTunes has an invalid signature.
    There is a very useful health related app I want to use but my software needs to be upgraded first.  Can anyone help me please?
    Thanks very much, NathalieS

    I would delete the download and redownload the updat file.  It is located here for a PC

    For a Mac you the Fibder search and search for *.ipsw

  • Download always get a stub, I want the actual exe to save for other computers

    I want the full copy of firefox not the stub. The stub seems to be for downlad and install. I want to save the full exe and then install on a number of computers. I have tried many ways to find the full exe but I always get transferred to the stub. Up to now I was able to get the full exe. Where have you hidden it? I have to be careful with download quotas and speeds.
    I am using 25.0.1 Windows XP and have used firefox forever!

    By the way, if you are on visiting the Firefox page and have the current version, the secret to finding that link is on the right side where it says "Download a fresh copy".
    If you are visiting from another browser, below the large green button, there is a link labeled "Systems & Languages" that leads to the page with the full installers for all of the languages.
    Not obvious, I agree.
