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.

  • 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?

  • 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'd first try downloading an installer from the Apple website using a different web browser:

    If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

  • 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.)

  • How to add a digital signature in xml publisher report

    The problem is: There is a existing pick slip report.This is a xml publisher report and the data source is RDF. We have to add digital signature there. Now this signature is stored in a table with type Long Raw and format BMP. XML Publisher do not support Long Raw and BMP format. It supports BLOB and jpg format.

    I reinstalled Itunes a couple of times.  I unistalled all programs that I never use, I updated all of my drivers, Windows swept my computer and found no problems.  I have a yellow causion lite when I look at the USB-port with the phone connected.  All other devices work without a problem.

  • How to inclulde digital signature in PDF outputs using XML Publisher

    I'm working on AR invoice print report which is a custom report. One of the requirements of this report is to include the digital signature in the output which is in PDF format.
    We have below code components for this custom report.
    Oracle Report (RDF) - to extract the invoice data
    RTF template - for report layout
    Bursting file - to split the output into individual PDFs
    Is there any document available to implement the digital signaure in my case?
    I'm looking for the steps to implement this in my custom report using XML Publisher.

    Take a look at the report designer's guide; section "Adding or Designating a Field for a Digital Signature" here:
    http://download.oracle.com/docs/cd/E12844_01/doc/bip.1013/e12187.pdf
    Thanks,
    Bipuser
    If I am not mistaken, this would require using PDF templates and use of Adobe Acrobat Professional.. Maybe others can chime in with other/better options..

  • Digital Signature on pdf Invoice generated by BI Publisher

    Hi,
    Can BI Publisher add a digital signature to a pdf invoice to certify it when viewed by e-billing ?
    Do you know if this has been done elsewhere. BI Publisher needs to call the local authority responsible for digital signatures to sign the pdf invoice file.
    Thanks for your input.

  • Itunes wont install on vista, No digital signature

    I had a problem were Itunes would not update or anything Apple related (quicktime etc) so i deleted Itunes and tried to run it as a fresh copy.
    Yet when i download it and try to run the application i get the box from windows asking me if i want to run it, but in this box next to publisher it says unknown.
    When i click run nothing happens. The box disappears and thats that.
    If i click on the application and go into properties and go into digital signatures it says the digital signture is not valid. Ive tried downloading it with Explorer, Firefox incase that was it. I have even done a clean install of windows and tried to install itunes first incase there was a conflict.
    Can anyone please help because its driving me nuts!

    Mr. Peck-- Would like your advice re: where to post this question. I cannot update ITunes and Quicktime to the newest version using apple update in the windows environment. I have tried disabling antivirus software without help. Error is that it is not receiving a "valid signature." Installation on the mac side of updated quicktime and Itunes works fine. Windows version is XP SP3-- with appropriate updates.
    Is there a solution that you know of? Where would you suggest posting this question?
    Thank you,

  • Firwfox will not download using Windows vista - shows unknown publisher

    The unknown publishers issue seems to hinge on an problem with the digital signature. The error message is as follows:
    Internet explorer security warning
    Windows has found a problem with this file.
    Name: itunessetup.exe
    Publisher: unknown publisher
    This file was blocked because it does not have a valid digital signature that verifies its publisher
    The reason I was downloading Firefox in the first place was that I have this same issue when trying to dowwload i-tunes. One of the support groups suggested that downloading i-tunes through Firefox avoided this issue.
    Grateful for any ideas!

    Are you downloading and saving the files to a folder on the computer?
    Don't click the Run button in IE to run the program directly, but save the file to your hard drive.

  • No Valid Digital Signature

    I'm trying to install the latest Itunes, but my computer won't let me becuase it keep saying that the publisher is unknown and the file was blocked becuase it does not have a valid digital signature that verifies it's publisher. I have no clue what to do. I have a Windows XP system.

    These can be frustrating.
    Try restarting your PC.
    Using a different browser.
    There have been reports that this can be due to router problems.
    A simple way round it is to get a friend to download the installer for your and put it on a USB stick.

  • 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.
