  • Can't install iTunes update on Windows XP 5.1

    Hello
    Hope someone can help. I downloaded the installation manager for the new iTunes update but when I go to intall it I get a message that says:
    Internet Connection Error
    We're unable to connect to the download server. It seems that your internet connection is down or firewalled.
    Please check your Internet and Proxy settings and then click the "Try Again" button below.
    It's clearly a firewall issue - a couple of other programs I want to install also hit the buffers as soon as they try to connect to the internet. I've turned my Windows Firewall off and rebooted and still nothing. Any suggestions anyone? I'm using Windows XP 5.1 by the way.

  • Can't install iTunes updates or even uninstall/reinstall program - help!

    I'm running iTunes 10.1.2.17 on XP but cannot upgrade to latest version. Neither can I uninstall and reinstall from scratch. Despite closing all other programs, I keep getting a message saying, 'the feature you are trying to use is on a network resource that is unavailable.' It then says, 'click OK to try again, or enter an alternate path to a folder containing the installation package 'iTunes.msi'. I've tried uninstalling it using the XP Control Panel and also Piriform's CCleaner but either way I hit the same problem. Here's hoping someone can advise! Thanks!

    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 June 25. 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. 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 iTunes entries and click "Remove".
    Quit out of CleanUp, restart the PC and try installing iTunes again. Does the install go through properly now?
    (If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

  • Hi everyone. I am getting the Invalid signature message when installing Itunes and when I try and download directly from apples page I'm prompted to save the EXE.setup file and then nothing happens, it goes straight to the "thanks for downloading itunes"

    Hi all, as Ive said in the question, anyone help me with this, have tried most of the suggestions Ive found so far.
    Stephen

    No, Nothing happened, nothing was downloaded. When I say nothing happened I mean NOTHING HAPPENED, What can I say to make it more clear. How could I run a file that wasn't downloaded.....Nothing happened, rien, nada, b***** all. Why would I post a message saying "When I press the Save button nothing happens" if something had been downloaded.
    I've found out why. It is because I am using Firefox. Presumably a case of Apple treating us users of the superior Operating system (Windows) with distain.

  • Itunes 10.7 wont startup or run on windows 7 64 bit,, while downloading it from previous version of itunes say invalid signatures.

    whenever i used to download something from itunes it restarts in mid,, and starts again and does the some for a long time and atlast says error 8008. Then i tried to upgrade it new itunes would download for some time then gives error saying invalid signatures,, I then downloaded itunes 10.7 from apple website.. download completes and it wont run.. wont start up.. I have tried Run as administrator used new user accounts, downloaded it again and again deleted temp folder aswell, deleted itunes library from my music folder aswell, done everything i found in discussions but that wont help,

    Apologies about the delay. I've been brooding.
    Although we don't know where the specific relevant keys are on modern versions of iTunes, there's a shotgun approach we can take to dealing with them, which has a reasonable chance of success in this case. The complicating factor in your case is that you've got a 64-bit Windows. So there's an extra hoop to jump through.
    The basic approach is the procedure from the following weblog entry:
    [Solving setup errors by using the SubInACL tool to repair file and registry permissions|http://blogs.msdn.com/astebner/archive/2006/09/04/solving-setup-err ors-by-using-the-subinacl-tool-to-repair-file-and-registry-permissions.aspx]
    The complicating factor is that we have to make an additional edit to the reset.cmd file.
    When you're in Notepad, replacing the two YOURUSERNAME values with the name of your Windows 7 user account, in the first line of the batch file, replace the:
    %programfiles%
    ... with:
    %ProgramFiles(x86)%
    (On a 64-bit Windows system, subinacl is installed in a different location than on 32-bit systems. So unless we make that change, the reset.cmd isn't going to be able to find subinacl and the reset.cmd won't work.)
    While you're in Notepad editing the file, make sure each of the nine lines of the file start of a new line. (Sometimes they get smooshed up together on a single line, and then again the reset.cmd won't work.)
    I'd strongly suggest setting up a System Restore point immediately prior to running the reset.cmd. There's instructions on that in the following document:

  • Why cant i download latest version of itunes, keeps saying invalid signature

    Why can't I donwload the latest version of itunes to my windows Pc? It keeps saying 'invalid signature'.

    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?

    Hello, I was trying to upgrade my iTunes for windows 7 PC, but because of invalid signature error I removed iTunes as well as all apple related applications. While reinstalling it , When I click link to install iTunes it immediately says '' thank you for downloading iTunes'' but I don't find it in my system.
    I have tried all suggested option to solve it but all in vain. Please help me to get rid of this problem

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    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.
    The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
    Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.
