HT1926 Win 7 64, latest updates. iTunes won't update - error "iTunes has an invalid signature. It will not be installed'. Tried rebooting, nothing seems to work. Due for new phone - am seriously looking at Android.

Any suggestions? IE 9.0.8112.14621IC. Symantec End Point Protection 11.0.5002.3333. Latest MS patches, rebooted, nothing has changed on my computer in months besided the MS patches. This is crazy - spent more time on this already than it's worth.....

I'm searching for an answer to almost the same exact problem, using almost the same exact hardware and software. Has an answer been found?
The files that I'm trying to burn come from eMusic, and they are formatted mp3. Recently, (after the iTunes update to 9.2.3?,) they would not drag and drop from iTunes into Toast. From several different discussions I've tried working around this by dragging to the desktop first then dragging and dropping to Toast, going to Toast from a programmer's homemade help window, " iToons," and today, after talking with Apple support, going directly to Toast from my eMusic folder. Alas, all recordings do not perform like they use to. Sometimes they play and sometimes not. There is one I managed, that is listenable, but sometimes I have to put it in my car stereo over and over again as it gets ejected with an error code, sometimes, finally it takes it... Some of the recordings on other disks I've burned are not clean - they have white-noise sounds creeping in... I use to have none of these problems. One time as I was listening to a CD that managed to play, and it just stopped playing... Is there an answer out there to get back to how it use to be? Thanks for you help.

    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 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.

  • 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.

    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)

    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?

    Are you downloading iTunes form an Apple website or somewhere else? If the answer is somewhere else, try downloading it from Apple. Click on iTunes in the black menu bar above and go from there.

  • Everytime that I attempt to download iTunes version 11.1 right before the download finishes, it says that iTunes has an 'invalid signature'. What can I do?

    I normally do not update my iTunes, but after the iOS 7 release, iTunes 11.1 was required in order to download this. I attempted to update, but right as the download began to finish, apparently iTunes has some sort of "invalid signature". This was not a problem, but then I upgraded to the iPhone 5s, and in order to transfer my music, apps and contacts to my new phone, this became a problem. I tried to update both on my desktop and my laptop and both came up with the same response. Is there any way to troubleshoot this or maybe transfer these things another way? I would rather not manually enter my 500 contacts into my phone.
