Downloading and installing latest version

When I try to install the latest version of itunes I get this message. "iTunes & Quicktime has an invalid signature. It will not be installed" Does anyone know what this means and how I can fix it?
Thanks

Try installing QuickTime standalone. Make sure you pick the version withOUT itunes.

DOes that install OK? If so, iTunes might install OK after it.

    Choose About this Mac from the Apple menu.
    If you have a PowerPC Mac, buy a new, secondhand, or refurbished Intel Mac.
    If you have an Intel Mac, phone the online Apple Store and order a Mac OS X 10.6 DVD.

  • Can't download and install latest version of Flash...

    I have tried several times to download and install the latest version of Flash player. It says it's downloaded, shows me that it's installing, then, when I click "Finish", it takes me to a website that says "Step 3 of 3", but is otherwise blank. I continue to see an error message on websites that require Flash; the error message tells me that Flash is out of date. Not sure how that's possible, since I just (supposedly) downloaded and installed the latest version from the website. I have walked through all of the troubleshooting steps on the Adobe site, with no luck. It's quite frustrating. What else can I do?

    Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

  • Download and install newest version but still get error - "requires latest version of flash player"

    I keep getting a message that something won't work because the latest version of flash player needs to be installed.  I go through the download and install for flash player but still get the message.  After the install I never get any setup steps.  I have tried uninstalling what ever version of flash player is on my computer before the download and install but it doesn't help.
    I also tried to delete Adobe photoshop Elements 9 and Adobe Premiere Elements 9 but I could not get it to work. I get a message that "This action is only valid for products that are currently installed."

    Removed your phone numbers as I'm assuming you don't want these posted on a public forum.
    Can you try going through the steps outlined in the two faq's below.  Also, where you able to go to the Flash Player Version page and see both the animation and flash player version number displayed?

  • Unable to boot computer iMac intel after downloading and installing latest iPad software

    I downloaded and installed the latest iPad software and my iMac will now not boot up. The iMac was getting a little slow just prior. Is one year old and this is the first problem. I have put the system DVD in and rolled back a couple weeks. Still no start up.

    Sorry. I downloaded the latest iPad update through iTunes using my iMac. Then synced the iPad to update the iPad. Updated iPad is fine. iMac will now not boot up. I put the iMac osx install dvd disk in and used it to rollback two weeks. No help. I am now running the disk verify program from the osx install DVD
    There is no rollback feature on the OSX disc (which version of OSX is this, Leopard, Snow Leopard?) so I am unable to understand this unless you are referring to a restore from Time Machine, is this what you did?

  • Just purchased a ipad2, could not us it on my MacBook 10.4.1 - Purchased and installed OSX Snow Leopard 10.6.3 - downloaded and installed latest itunes, set up a itunes accounts and tested by purchasing an album and app, ipad does not show in devises?

    I just purchased a ipad2, it would not work on my MacBook 10.4.1 I purchased and installed OSX snow leopard 10.6.3 downloaded and installed the latest itunes, set up an itunes account, purchased some music and apps.  When i plug in my ipod it shows up and works, but when i plug in my new ipad the ipad screen comes up with a display of a cable and itunes but does not show in devises, i have tried all the resets and different USB ports with no success.  Any ideas short of selling it on ebay or buying a new computer?

    If you've already tried the usual rebooting of the computer and ports and stuff, there is only a few things left I can think of. It's possible that when you updated iTunes it didn't fully replace all the files, so I suggest just manually removing iTunes and then reinstalling it.
    Try removing iTunes manually first http://support.apple.com/kb/HT1224 then download a fresh copy, make sure it is 10.3.1
    It is essential that you go through Finder to remove those files it mentions. Otherwise they won't be reinstalled when you run the installer again.

  • Tried to download and install latest iPhone update

    I clicked "Download and Install" when prompted to install the most recent iPhone update and I got this message:
    There are purchased items on the iPhone that have not been transferred to your iTunes library. You should transfer these items to your iTunes library before updating this iPhone. Are you sure you want to continue?
    What do I need to do (specifically) as I don't know what this it talking about.
    Thanks

    This mean there is an app or some other Store content on your phone that you do not yet have in your iTunes library.
    In your iTunes menu bar go to file> devices > transfer purchases to move them to your library before you update the iPhone.

  • After Downloading and Installing any version of Camera Raw after 8.3 the installation completes but 8.3 remains, how can I resolve this?

    I am using Windows 7 Home Premium, with Adobe Design and Web Premium CS6.. I previously had this same problem installing Camera Raw 8.3  and as a work around back then, Adobe Support manually edited the Registry of my Windows 7 laptop to enable Photoshop CS6 and Bridge CS6 to recognise the Adobe Camera Raw 8.3 software so I could edit my files from my then new Nikon D610 camera...  Now when I receive and install any updates for Camera Raw the installation says it was successful but the old 8.3 version of Adobe Camera Raw remains when launched via Bridge or Photoshop..  which means I am unable to edit any files with the New Nikon D750 , or even the D810, can someone please help me solve this issue once and for good.. Thanks, please?!

    Download the latest version: Parallels Desktop 8.0.18483. Uninstall the one you have then install the new version. The uninstaller will either be in your Applications folder or on the disk image for the version you now have installed.

  • After downloading and installing latest ver of flashplayer it will not register  What to do?

    This problem started with an update for flash player several months ago.  I am using windows XP home and Internet explorer 8.  Flash player always downloads however the installation fails to register active X component.  No flash player.  I haven’t seen any info on this problem. Dont know what to do
    Buford  

    This happened to me today as well post installing the latest version of itunes.   I did a search on google for the error and came across a recommendation to :
    Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the msvcr80.dll error.
    If, and only if, you're receiving the msvcr80.dll is missing error when you open Apple iTunes, do the following: (skip this step if your msvcr80.dll error is occurring with a different program)
    Uninstall from Windows the following five programs in this order: iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, and finally Apple Application Support. If you have iCloud, remove it as well.
    Uninstalling these programs in Windows is done from an applet in Control Panel called Programs & Features (in Windows 8, 7, or Vista) or Add or Remove Programs (in Windows XP).
    Note: Songs and playlists in iTunes will not be removed when you uninstall the iTunes program or any of the other, already-mentioned Apple programs. If you'd still like to back them up, they're usually located in the My Music folder in Windows.
    Download the latest version of iTunes from Appleand note the location you're saving it to so you can find it once it's done.
    Run the iTunes installation as an administrator. If you're not sure how to do that, see How Do I Open an Elevated Command Prompt? for help. That procedure shows you how to open the Command Prompt program as an administrator, but the steps are essentially the same for anything, including the iTunes installation package you just downloaded.
    A general overview of removing and reinstalling iTunes can also be found here on Apple's site but the above procedure seems to work better in this particular situation.

  • Firefox.exe has "disappeared" so I can't open it. If I download and install new version will I lose all my bookmarks etc?

    I've had a lot of crashes, some just firefox, some the whole computer. In process of migrating to new machine so wasn't overly concerned. But after a restart today, I found I could not get firefox to open at all. After finding the system searching for firefox.com, I checked program files\mozilla firefox and firefox.exe is not there. A search showed it not to be anywhere. Not ready to stop using this machine just yet. Any way to get firefox.exe reloaded without losing all my related stuff??

    As long as you do not delete your Firefox personal settings or application data, they should remain after a reinstall.
    Don't run the Firefox uninstaller, simply run the installer that you download. This will just install over your previous installation.
    <b>Note:</b> To be 100% safe, I would recommend backing up your Firefox application data folder.
