Digital Signature/unknown publisher on ITunes download

I cannot download Itunes to install on my new lap top because every time I do I get the message that the publisher is unknown/there is no digital signature on the download. Can someone help me install Itunes please?

Welcome to AD!
Several folks have posted that the problem turned out to be QuickTime, which iTunes requires and installs in a bindle with some other programs.
Try installing the QT standalone program first - do you still get that publisher message?

  • Digital Signature/Unknown Publisher

    So I was trying to download iTunes 10.5. The first time I did it a "digital signature" message popped up and then retarted the download, but it popped up again. I went on to this discussion board to find some help. Some discussions said to delete (remove) everything apple and restart the iTunes. I did this and now I am getting a message that says "unknown publisher" everytime I click the "run" button. I have tried to download this iTunes about 8-10 times in the past two days.
    some discussions say to try Firefox, but I don't want to do that. My last resort is to call the tech support and ask them for help because last time this happened it took us about a couple of hours.
    Thanks in advance!

    How are you downloading iTunes?
    Generally speaking it is best to download it from here:
    http://www.apple.com/itunes/download/
    Rather than using update. You need to save the file on your PC and run it from there.
    If that doesn't work can your try another browser?
    Also it might be worth restarting your router.

  • Getting an "unknown publisher" error when downloading itunes

    I am trying to download the latest version of Itunes.  I keep getting an "Unknown Publisher" message from Internet Explorer.  I went through the troubleshooting and removed all apple apps.  Now I am stuck. Any ideas?

    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?

  • Install blocked does not have a valid digital signature verifying publisher.

    Windows XP blocked the install. Error message was:
    Unknown Publisher. Does not have a valid digital signature that verifies its puiblisher.

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

  • I get an error message "unknown publisher" when I download quicktime 7.7 for windows 64bit

    I am trying to download quicktime and I get an error message :unknown publisher".  I am using windows 7 64-bit operating system. Can anyone help me?

    Which I get. But clicking on that link you provided does not give you the option of choosing between 32 and 64 bit installers.
    Yeah, that was certainly a 32-bit installer file being referred to in the other message, too. (The 64-bit installer file is called iTunes64Setup.exe.)
    Just in case it's an issue with your normal browser not working properly with the system-detection equipment on the page (there's a javascript control that checks for operating system specifics, and is supposed to deliver the correct Mac or Windows installers), let's try a different web browser for the download. If you use Firefox instead of IE (or vice versa), do you get offered an iTunes64Setup.exe instead of an iTunesSetup.exe?

  • I can't run Itunes! After installing Itunes, I receive a message saying that Windows could not verify Apple's digital signature and it closes.

    Pls HELP me! I can"t install it Itunes on any of my computers. After downloading it ( Run now or Saving it) it will no run because I keep receiving a message saying that Windows can not open this file because it could not verify Apple's Digital Signature. I have changed my internet security settings to allow downloads from unverified websites but it will not allow me to run Itunes. I had an older version of Itunes so I tried to install the update and it wouldn't work because so the same message about not being able to verify the digital signature.  I uninstalled Itunes and Quicktime and all other Apple programs on my system. Then I tried to download it again... no luck the same message came up again. I then went to my other computer that NEVER HAD ANY APPLE software on it and tried to download Itunes. It gave me the same message. Please help me, I'm going crazy tring to figure this out.

    I had this same issue occur today during update, searched and finally tracked to problem with windows registry. Used online version of windows registry tool "Fix It" (can also download portable version for offline check. I selected Apple updater utility from list to fix and it did it's thing. Returned to my downloaded 10 iTunes adn isntalled perfectly fine.

    Good luck. Worked for me back up and running.

  • Cannot download firefox... due to error of unknown publisher using windows 7

    firefox%20Setup%203.6.13.exe
    unknown publisher
    could not download
    previously was downloaded...and I was reinstalling it... but can't... I changed my security setting to Medium to see if this would help

    Yeah, the 64-bit tip isn't going to help.
    Let's instead try reregistering your Windows Installer Service.
    First, launch a command prompt as an administrator. In your Start search, type cmd then right-click on the cmd that comes up and select "Run as administrator".
    At the command prompt:
    Type %windir%\system32\msiexec.exe /unregister and hit enter.
    Type %windir%\system32\msiexec.exe /regserver and hit enter.
    Close the command prompt, restart the PC and try another iTunes install.

  • Broken Digital Signature

    So in the process of updating my phone... some how or another it crashed because it would not even come on anymore so apple sent me another one... this time the mic didn't work... so apple sent me another one.. can't sync any apps or my contacts. An error message appears saying that one or more applications were not synced click the + for more info. I click the + and out to the side of each app it says app was not synced because app is not signed. When avg did a scan it reported that the digital signature was broken for iTunes. I have tried reinstalling iTunes ( the correct way) and still no luck. Does anyone else have a solution for this?

    I get this message in the AVG Anti, should I be worry???
    It's merely an oversight by Toshiba. Tell AVG to ignore the situation. 
    Or you can download the current version of the chipset software. The file has been updated.

  • Cannot install itunes - message "unknown publisher & no digital signature

    I have been using itunes for ages but on Tuesday when i tried to update my IPOD it froze so i then checked that i had the most up date itunes by downlading the latest version which i have done loads of times without any problem. THis time however every time it downloaded it came up with the error message "unknown publisher" and "no digital signature". It gave the option of running the program still but then it would just close and not do anything!!
    I have been to the apple shop and my ipod has been sorted although everything has been wiped as they had to restore it. I have again today tried to download itunes but am still getting the same message so cannot put music back onto my ipod to use!!
    I use windows vista and have an ipod touch. We hav also tried another computer but are still having the same problem. Any ideas??
    Thanks

    Should I just get the itunes setup folder from a person that has got it already?
    Yes, that usually works. (So long as we can get an undamaged installer onto the PC with one of these, it will usually install fine.)
    Another thing that is worth a try is seeing if you can connect to a different wireless network, and downloading the installer while you're connected to the internet that way. (The wireless router being grumpy is a common cause of this sort of thing, so by connecting to a different network you're taking the grumpy router out of the equation.)

    All help would be appreciated

    I don't believe that model has a recovery partition. If you didn't burn the recovery discs, then you should order them.

  • Download itunes 10.3 - unknown publisher??

    when i try to download itunes 10.3 I am getting a internet security warning pop-up screen that states Name: itunes64Setup.exe  Publisher: Unknown Publisher... then it goes on to say that 'this file has been blocked because it does not have a valid digital signature that verifies its publisher.'  How on earth could it be that Apple would not be up to date? any ideas as i reckon i have tried this 10 times now. I also tried to save the file and then open. that doesnt work either. I am set up as administrator so that isnt a problem i dont think....??

    Hi.
    I was having the same problem. Have you rectified the issue since your post.
    if not, are you connecting to the internet through a wireless router. if so you need to connect through a LAN and this will allow it to be installed.

  • Cant download itunes update dur to Unknown Publisher - please help!!!

    Please help me I don't know what to do next. When I try to update itunes it downloads but then comes up with a message telling me download failed due to unknown publisher. I tries following advice from another post but this didn't work.
    Thanks in advance
    PS also cannot download new iphone software but i will post that in the iphone section ...

    Thanks that worked - do you know why that is?
    excellent news, Jay.
    We (the one's of us who are troubleshoting the error) think it's something to do (in some cases) with the network settings on certain kinds of network setups (possibly if you're connecting to a LAN which has an internet gateway, rather than, say, connecting wirelessly to a router plugged into a DSL or Cable modem. Bloody Yeti discusses that in this post:
    http://discussions.apple.com/message.jspa?messageID=10547579#10547579
    Off in a different thread (I've just discovered) Bloody Yeti was also simultaneously discussing trouble with recovery mode, so plausibly the two issues (getting the ipod software and getting the iTunes installer) are connected:
