unable to install new iTunes as it states it has an invalid signature. what is this.

That one suggests the installer has gotten 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 am unable to sync my phone as my mac requires new version of itunes, but when i try to install it says i have the lastest version. can anyone advise what i can do to install the latest version?

    Hello turley00
    Check to make sure that your computer meets the system requirements for the latest version of iTunes which is running OS X version 10.6.8 or later. You can check to see what operating system you are running by going to the drop down menu  > About This Mac. If you are not running at least 10.6 or higher then you will need to upgrade your operating system. I have provided a link to get that upgrade.

  • Unable to Install new iTunes - Already Removed Old iTunes

    Hello,
    I attempted to install the latest iTunes after downloading it a few nights ago, as it was apparently required if I wanted to download movies. I got "Error code 2738" continuously.
    I removed the old iTunes and made sure that nothing else related to it was running. I also removed the old QuickTime.
    Now, in attempting to install iTunes OR QuickTime, I still get error code 2738. I now have no way to access my iPod or to download new music, as I now have no iTunes or Quicktime. Please help!
    Thanks!

  • Unable to install new itunes or remove old itunes program

    Short story: I had to move itunes program from computer onto external hard drive. Copied the program from external hard drive to reinstall back onto computer. Now I can't open itunes program, remove it, or install a new version. Is this because it is a copy and not the original program file? I no longer have the original file. What can I do?

  • When updating to iOS 5.0.1. get the err -3259, thus unable to install new iOS. The message I receive goes: "THE NETWORK CONNECTION TIMED OUT.  MAKE SURE YOUR NETWORK SETTINGS ARE CORRECT AND YOUR NETWORK CONNECTION IS ACTIVE, OR TRY AGAIN LATER."

    When updating to iOS 5.0.1. get the err -3259, thus unable to install new iOS. The message I receive goes: "THE NETWORK CONNECTION TIMED OUT.  MAKE SURE YOUR NETWORK SETTINGS ARE CORRECT AND YOUR NETWORK CONNECTION IS ACTIVE, OR TRY AGAIN LATER."
    Does anyone know how to solve this tiresome problem, please!?? The update is downloaded upto 723.5MB, and is required upto 723,6MB, then the error message pops out! Tnx.

    I have a quick wifi connection (Mac shows it as about 35 megabits) but I couldn't get the 5.0.1 OTA to work, I had to do it via cable to my computer's iTunes - and as I was already on iOS 5 it was only a small download, basically the same size as the OTA size.
    As the original poster is talking about a 730 meg download then I assume that they are still on iOS 4.3.5 or below and can therefore only download via their computer's iTunes - you need to be on iOS 5+ before you get the OTA option.

  • Due to virus attack i had to format my windows laptop...now when i installed new itunes software i had to sync my ipod touch again but it says that if do the same then the data on my ipod touch will be erased....how should i protect my ipod touch data?

    due to the virus attack i had to format my windows laptop...now when i installed new itunes software i had to sync my ipod touch again but it says that if i do it then the data present on my ipod touch will be erased as it is syncd to some older library... how should i protect my ipod touch data?

    With all you media (apps, music) in the iTunes library connect the iPod to the computer and make a backup. Do that by right clicking on the iPod under Devices in iTunes and select Back Up. Then restore the iPod from that backup.
    Note the the iPod backup that iTunes makes does not included synced media like apps and music.

  • I can't Start, Uninstall or Install new iTunes. I'm getting the same error message: Window Installer Service could not be accessed.  No other programs have similar problem. Any suggestion what can be done?

    I can't Start, Uninstall of Install new iTunes. I'm getting the same error message: "Window Installer Service could not be accessed". No other programs having similar problem. Any suggestions how to fix it?

    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) (not for XP) 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.
