Quicktime and itunes will not open - buffer overrun in quicktime

I cannot open Itunes. It says it needs quicktime. quicktime will not open. says buffer overrun. reinstalled both itunes and quicktime. both used to run prior to updates. Help.

Quicktime was working on my Vista computer up until a short time ago. I believe one of the Microsoft updates crippled it. I have looked at several forums and read the other threads on this site and from what others have described I really believe now that Microsoft did this with one of their updates. There are many problems with Vista all due to Microsoft trying to force developers to use only their products. Unfortunately they are squeezing us customers really hard.

  • Quicktime and itunes will not open error message

    I think their is suppose to be two files (QuickTime.qts and QuickTimeVR.qtx) in the systems 32 folder. But there is a quick.ime also in the folder, do I delete it so that my quicktime and itunes work.

    No, quick.ime is not part of Quicktime. Don't delete it.
    If Quicktime will not open, then iTunes can't work.
    Can you give the Quicktime error message in full, and also check in your Windows error logs or Problems & solutions to see if there is more information there.
    You haven't given your Windows version which helps when troubleshooting.

  • Safari and iTunes will not open on my Macbook Air after Migration Assistant

    I did the Migration Assistant via wireless (from Macbook Pro TO Macbook Air) last night and it did work. However, my Safari and iTunes will not open on my Macbook Air now. The error messages are as follows:
    Safari: "Safari quit unexpectedly. Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple."
      - I tried reopening the app, restarting, and shutting down the computer. Nothing has worked.
    iTunes: "The file 'iTunes Library.itl' cannot be read because it was created by a newer version of iTunes. Would you like to download iTunes now?"
      - I clicked "Download iTunes" but then another message comes up that all my software is up to date.
    Any help is very appreciated.

  • The iphoto and itunes will not open please help

    on my Mac G5 the iphoto and itunes will not open can anyone help

    Could be many things, we should start with this...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    Then, hold the Option key down when trying to open iPhoto, does it ask where it's Library is? Or what exactly happens?

  • Just bought a new pc and itunes will not open. I have tried thto repair and reinstall but still no itunes

    just bought a new pc and itunes will not open. I have tried thto repair and reinstall but still no itunes

    Best route here is to uninstall iTunes completely using the Windows Control Panel.
    Make sure you know exactly which version of Win 7 you're running.
    Restart your computer from cold (with no iTunes).
    Go to Apple website and download the correct version for your operating system.  Install following Apple prompts.
    Once installed, close iTunes.
    Restart your computer from cold (with new iTunes).
    Start iTunes - all should be operating well!  Good luck ...

  • Quicktime  and Itunes will not launch!

    Both quicktime and itunes come up with errors whenever I try to lauch them. I have tried nearly EVERYTHING and they will not start! This is quicktime error-
    Quicktime Player has encountered a problem and needs to close. We are sorry for the inconvenience. Error signature is BEX

    Interesting. In that case, the errors are probably being caused by the absence of the two files I mentioned earlier. Haven't seen one of those for a while.
    We'd better swap out your existing QuickTime. We'll take a few additional explicit precautions along the way, just in case.
    First, download and save a fresh copy of the QuickTime installer (QuickTimeInstaller.exe) to your hard drive. (Don't run the install online, and don't start the install from the downloaded installer just yet. Use the download option that doesn't mention iTunes.)
    http://www.apple.com/quicktime/download/
    Now head into your Add or Remove Programs control panel. Uninstall QuickTime.
    Next we'll clear away any leftover QuickTime program files or folders.
    In "My Computer" open "Local Disk C:" or whichever drive your program files are installed on.
    Open the "Program files" folder.
    Right-click on the "QuickTime" folder (if it still exists) and select "Delete".
    Empty your recycle bin and restart the PC.
    After the PC restarts, do not open any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
    Now start the reinstall by doubleclicking the QuickTimeInstaller.exe file you downloaded earlier.
    Reenable all security software prior to reconnecting to your network and/or the internet.
    Did the QuickTime install seem to go through properly? If so, are iTunes and QuickTime launching for you now?

  • New version of iTunes will not open says problem with QuickTime

    Followed all instructions to unload/reload QuickTime still same problem iTunes will not open due to problem with QT so removed both iTunes and QT and reloades still shows message and will not open iTunes.

    Try uninstalling the QuickTime Player application using the Windows Installer Cleanup Utility, as suggested here: http://support.apple.com/kb/HT1926.
    Also, *Verify iTunes and related components are completely uninstalled*, as suggested here: http://support.apple.com/kb/ht1925.
    Then download and install the latest version of iTunes from here: http://www.apple.com/itunes/download/

  • Installed 10.4 update and itunes will not open

    Installed itunes10.4 32 bit version - after successful installation itunes will not open
    any advise?

    Update to my last post.  I have finally "fixed" whatever problem was causing the Apple software products to malfunction on my PC, Windows Vista 32 Bit SP2.  After updating to iTunes 10.4 and Safari 5.1, a series of error messages would appear:1) AppleSyncNotifier.exe 2) iTuneshelper.exe 3) iTunes Failed to properly install - Error 7 (Windows error 126).  I had tried uninstalling and reinstalling iTunes & Safari as well as downdating iTunes to an earlier version, but this had all failed to correct the problem and the error messages still appeared when the programs were suppose to have been removed. 
    I ended up using the Windows Program Manager (in Control Panel) to remove every single Apple product from my PC, including the Apple Installer.  Then I restarted the system.  Taking bits and pieces of advice from this forum, I started the system, went to the Apple website, downloaded and SAVED the newest iTunes version (which includes QuickTime), but did not run the program.  Then I disconnected from the net, turned off all virus and firewall protections, and finally installed the saved iTunes program.  It took an extraordinarily long time to complete the install, but I was able to restore my libraries from my iPod Touch (4th gen) by performing a simple sync.  I reconnected to the net and updated the device software . . . so far, so good [knock on wood], no error messages yet.  I will add each of the removed programs as they are needed in the future so that whatever conflict exists can be fixed - until then, I'm at least happy to have iTunes back!  Hope this is helpful to someone and saves them the 4 hours it took me to get back on track

    Hello db133,
    Thanks for using Apple Support Communities.
    From your post I understand that you're unable to open iTunes after installing it due to an error with the Apple Application Support.  I see that you've gone through and reinstalled multiple times, but there are specific steps for removing and reinstalling iTunes which I think would help resolve this issue.  Those steps are found in the article linked to below.

  • Accept Liscense Agreement and Itunes Will Not Open

    I upgraded to current Itunes software and have not been able to open ever since. I have Windows XP. I have tried installing with antivirus turned off. I have tried installing quicktime standalone and then itunes. I have followed all the troubleshooting and nothing has worked. When I try to open Itunes after the install the liscense agreement pops up, I accept and nothing happens. Any suggestions?
    HP   Windows XP  

    My Itunes just popped up after about 2 hours of launching. Is it possible that it had to upload my music library and that is why it took so long to open?
    hmmmmm. by any chance, have you got qttask.exe disabled on that PC? that's been linked to incredibly slow startups (though more on the order of minutes rather than hours).
    here's some info on the itunes background processes:
    Background processes installed with iTunes 6 for Windows
    ... and if you want to check to see if any of them have been disabled on startup, see:

  • I downloaded new itunes,now my itunes file is gone and itunes will not open,it tells me to reinstal i have done this 10 times and still cannot open itunes! then when i try to repair it it says "A installation package cannot be found!? help!

    my itunes cannot be found,after i downloaded the new version of itunes.

    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 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.

  • TS3074 updated iTunes on Vista on Jan 26, 2014 and iTunes will not open.  First message "unable to locate component- MSVCR80.dll was not found" then "iTunes was not installed correctly. Please reinstall iTunes - Error 7 (Windows error 126)"

    I even deleted iTunes losing all my data and thesame thing happened when I reinstalled iTunes, several times! Now I cannot use Apple TV. Frustrated.

  • Itunes will not open on win 7 pc after oct update?

    I am running a win7 pc-64bit os and itunes will not open since I updated it in Oct. I have attempted uninstalling and reinstalling the itunes s/w several times. I have tried without a firewall and with anti-virus programs disconnected. I do not get an error message. Itunes launches with a blank screen and the busy "spinner" spins until I reboot. Anybody with a similar problem or a solu

    I don't know if this will help you  but I just went through this. After three weeks of thinking it was my firewall and making all the adjustments suggested by apple, I discovered it was my Net Nanny software that was blocking my way. I had one character wrong in the accepted lists on websites and so it looked right to me when I checked. It wasn't until I completely uninstalled the software and reinstalled, and re-entered all my lists that I realized the error. Now it is working great. So you may want to check your list of approved websites VERY carefully or re-enter them on you firewall software or any content blocking software you may have.
    Hope that helps.
