Problems using/uninstalling itunes/quicktime

hi,
I tried using itunes and quicktime this morning and was not able to. i tried to uninstall the programs and re-install but was unable to uninstall quicktime using "add/remove" programs on windows. i installed the windows install update and uninstalled itunes that way, but quicktime didn't appear as something that could be uninstalled. every time i try to open itunes it says that the application needed to close - and quicktime won't open at all.
I am using windows xp.
thanks.

hi karen!
every time i try to open itunes it says that the application needed to close - and quicktime won't open at all.
just checking up on some things before we proceed.
(1) this error message appeared out of the blue? you had a functioning itunes 5.0.x prior to that?
(2) what was it saying? "itunes has encountered a problem ..."? or something about you only having QT 6.5 and you needed QT 7?
(3) if it was the latter message, have you installed or upgraded a K-Lite Mega Codec Pack recently? which version?
love, b

  • Why must I completely uninstall iTunes, quicktime etc. for every update?

    Every time I try to update iTunes there is a problem installing the iTunes software. I am forced to uninstall iTunes, quicktime, bonjour etc. every time! This is very irritating and takes a longgg time (considering I must also fully install it again). I have already tried deleting my Temp folder...Any ideas?

    Can you detail what "problem" arises? Is it the same problem every time, and if so what exactly is the error message. If you can provide that information, it will help people diagnose the problem and offer suggestions.
    One common problem, for any OS or application update, is antivirus and antispyware software. It's usually a good idea to temporarily disable any such utility prior to attempting any software installation or upgrade.
    Regards.

    Yep, there seems to be an issue with this. In addition to getting that error on my iTunes on my PC, I get an error when trying to update apps on my iPhone 5.

  • *Problems uninstalling itunes/quicktime after using windows install cleanup

    I was having problems installing itunes/quicktime 7.6. Everytime I tried to install it it would say that it does not have a valid digital signiture. So one of the suggestions I saw on this forum was to install windows install cleanup and use it on itunes and quicktime. So I did but all it did is mess up my old itunes/quicktime. Now when I go to try and uninstall itunes and quicktime from the add and remove programs in the control pannel it does not even show itunes or quicktime in my program list. Any suggestions??

    Ok, Update. I was able to remove itunes and quicktime manually after going into my windows task manager and to the processes tab and ended all processes involving itunes, apple, or quicktime. So now when I install itunes/quicktimes via apples site when it gets to the end it just disapears and nothing happens. I searched to see if it installed anything and it didn't, didn't even give me any reasons why. Can anyone help me with this?? It would help me a ton!

  • Problem uninstalling Itunes/Quicktime/Apple products from my computer?

    I have never had a problem with Itunes before, but recently, when trying to transfer newly downloaded songs from my Itunes, to my Ipod, the songs wouldn't sync. A message flashed up saying that I needed to re-install Itunes because Mobile Device Support was out of date.
    When I tried to re-install Itunes however, my computer didn't allow me to do so. Instead I was presented with a message saying that I was unable to uninstall Itunes because Windows Installer was not properly downloaded on my computer. However, this problem only occurs exclusively in relation to Apple products installed on my computer, as I am able to re-install other programs.
    I've tried every online solution offered and nothing works.No matter how hard I try, I can't re-install Itunes. Please help - I NEED MY MUSIC.

    Instead I was presented with a message saying that I was unable to uninstall Itunes because Windows Installer was not properly downloaded on my computer.
    What's the precise text of that message please, km?
    Do you have a 32-bit or 64-bit version of Windows 7?

  • Cannot install iTunes on my Win7Pro PC for several months after a long time w/o problems. Uninstalled iTunes Bonjour with no improvement.  Help?

    Since October 2011 I cannot update iTunes when I receive an Apple UD notice (Win7Pro PC).  I have also lost communication with my iPod Touch.  In all cases I have attempted to download the latest version of iTunes.  Yeasterday I uninstalled iTunes & Bonjour.  I still cannot install iTunes.  What can be done to allow iTunes to install?

    If you want to do complete reinstall, please follow following steps:
    1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes &amp; related installer files:
    http://support.microsoft.com/mats/Program_Install_and_Uninstall
    Be aware that Windows Installer CleanUp Utility will not remove the actual program from your computer. However, it will remove the installation files so that you can start the installation, upgrade, or uninstall over.
    2. You should remove all instances of iTunes and the rest of the components listed below:
    it may be necessary to remove all traces of iTunes, QuickTime, and related software components from your computer before reinstalling iTunes.
    Use the Control Panel to uninstall iTunes and related software components in the following order:
    iTunes
    QuickTime
    Apple Software Update
    Apple Mobile Device Support
    Bonjour
    Apple Application Support (iTunes 9 or later)
    Follow the instructions from Apple article listed here: http://support.apple.com/kb/HT1923 to remove all components
    3. Reboot your computer. Next, download iTunes from here:http://www.apple.com/itunes/download/ and install from scratch

  • Can't install or uninstall itunes/quicktime?

    I've been trying for a few weeks now to uninstall itunes and quicktime.
    Everytime I try uninstalling QuickTime, the following message comes up: "A newer version of QuickTime is already installed. This installation cannot proceed while the newer version of QuickTime is installed.
    When I try to uninstall the itunes that is on my computer or install a more updated version, I get the following message: "The Windows Installer Service could not be acessed. This can occur if you're running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance."
    I tried using a program called Revo to uninstall both of these programs but it will not work. :/ This is frustrating me to no end, and it's exceptionally frustrating because I've just bought a new ipod touch and I currently can't use it.
    Please help. 

    Everytime I try uninstalling QuickTime, the following message comes up: "A newer version of QuickTime is already installed. This installation cannot proceed while the newer version of QuickTime is installed.
    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. (The results from mydigitallife and Major Geeks are worth checking.)
    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 QuickTime entries and click "Remove".
    Restart the PC, and try another iTunes install.
    If you still get the following message:
    "The Windows Installer Service could not be acessed. This can occur if you're running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance."
    ... and you're on a 64-bit Windows 7, try the following instructions (even though they're for Vista, they're often applicable for Windows 7 too):

  • Error 1910 and problems installing/uninstalling itunes

    So i have been up at school trying to use my itunes to add more songs to my ipod on my new laptop. i installed itunes the first time around when i first got my laptop and one day it just stopped working. I have tried to remove the program entirely from my computer but when i try to do that it says "error 1910 could not find shortcut Itunes.ink" please verify file exists and try again. then after that message i get another saying error code 2330 there may be a problem with this package. i dont know what to do and i just want to get rid of it so i can start from scratch. please help.

    You can get this error when there is damage to the filing system. Try running a disk check to see if it finds any errors.

  • Problem with crashing Itunes & Quicktime

    So i've been having this crashing problem with both programs for a while now. I've tried reinstalling on multiple occasions, both the new version and the previous.
    I even went so far as to do a manual search through my registry and delete itune and quicktime reg keys.
    Whats happening is when ever i try running either program, or attempt to view a mov file through a plugin in either, IE, Firefox, or Opera, it crashes each browser respectively.
    I have also tried installing the stand-alone quicktime file. Which refuses to uninstall after installing when it doesn't work.
    I end up having to delete it and clean up the registry afterwards using ccleaner.
    Any ideas? This has been driving me nuts for a while and I hate having to avoid quicktime files like the plague.
    Plus i'd really like to use itunes with my ipod again.
    Thanks

    I do not have a solution but wanted to post a note to tell you that I am having the exact same problems, and have had them on more than one PC -- as have many of my friends and relatives! I think the whole "using iTunes on a PC" issue is a red herring for Apple in that there are a LOT of crashes going on out there as people try to install/use iTunes, install/use the iPod the first time, update software, etc. -- and some of these crashes create serious, serious issues, all the way up to corrupting the whole OS -- that no one at Apple seems to be talking about. I personally have had to rebuild two of my PCs from scratch over the past 4 months after various iTunes/iPod-related crashes. One was as recent as three weeks ago, and since I have had the Apple Updater software take over post-rebuild, I am constantly having the issues you speak of.
    The only anomaly I am experiencing currently beyond what you've described is that when I try to install the standalone QT -- directly from the Apple download site herein, by the way -- I am told a newer version(???) is already installed (I have never downloaded any Apple software from anywhere but the Apple site) and that I must first uninstall it if I want to install this standalone version -- all odd as this happens even if I've already uninstalled the entire iTunes/QT/iPod trifecta, rebooted my machine, and run a host of registry cleaners!
    So you are definitely not alone ... and if I didn't love using the iPod as much as I do, I'd have punted the whole Apple experience long ago (on my PCs, that is).

  • Can't uninstall Itunes / QuickTime

    Hi there,
    I upgraded QickTime to v7 and used Mozilla Firefox to find the latest update. It pointed me to a combined QuickTime / Itunes and as I couldn't find a standalone Quicktime Product (have now found), I downloaded and installed. QT didn't run the media as intended so I decided to uninstall and reinstall the standalone product. I can't uninstall either product from the "change / remove programs" as they are not listed. I tried Windows Install Clean Up but no luck there either. The QuickTime uninstaller does not work and Itunes does not show an uninstaller. How do I complete a clean uninstall of Itunes and QuickTime without using "change / remove programs".
    Thanks
    Howard

    Since the uninstall of IT, I am unable to run QT and all Icons have gone from the desktop and the Start menu (menu just has generic Win icons). Uninstall still doesn't work but no nanosecond error? message.
    good
    b gracious,
    Howard ... so the icons from the desktop have
    b completely
    gone? they haven't just been replaced by generic icons?
    there's something going on here that i'm missing ... if anyone else here has experienced anything similar, please feel free to make some contributions.
    okay, if the QT isn't showing up in Add/Remove, and Windows Cleanup isn't showing it, and it isn't launching, let's try proceeding with the manual uninstall. (if it does show up in Windows Cleanup now, let's run Cleanup first.)
    if it doesn't let you delete anything, let's try to see if there's a rogue QT process still running somewhere and shut that down too. try adapting Katrina's technique to your situation:

    with the QT 7 standalone reinstall:
    http://www.apple.com/quicktime/download/standalone.html
    ... it's best to download and save to the hard drive rather than running the installation on line. given that really odd things have been happening whenever we try to do something, it would be a good idea to shut down all applications running in the background first. there's information on that given here:

    keep us posted.

  • Problems Using the iTunes store from AppleTV

    Over the last month I've had large problems downloading content from the iTunes store using my AppleTV. For instance 3 weeks ago it took several attempts to rent a movie. Ever since Saturday I've been trying to purchase a season pass for Season 3 of Robot Chicken. Every time it would say "This content is being modified, please try again later." Got that again 10 minutes ago, got fed up and I went and pulled on the iTunes store on my computer and tried and it went right through, just like it should. I wanted to go this route, because if I buy it on AppleTV new episodes will be downloaded to it (I've found a way to download season pass shows I bought on AppleTV to my computer first, but not a way to do the reverse).
    More importantly, I've had just numerous problems and errors purchasing content from AppleTV. As iTunes on a computer doesn't have these issues, the only thing I can figure out is that the software still isn't right.

    I posted a similar problem last week about the inability to move past "See All" in Podcasts. What was happening to me was that I would click "See All" and I'd get a message saying the request could not be completed. After getting no response here, I called up an Apple Expert about the problem. When I described the problem, the Expert tried it on her Touch and ran into the same problem. She called up the iTunes folks and reported that there was a problem and they were working on getting it fixed.
    A couple of days later, instead of getting the "Your response could not be completed" it went to the default Music section as you describe. They must be working on it, but don't know why it hasn't been fixed yet. The Apple Expert said to call back if the problem persists, but I haven't had the time yet.

  • Problem using BufferToImage with Quicktime mov�s.

    I have modified the FrameAccess.java in an attempt to grab frames from a quicktime movie and output them as jpeg sequence. While I can use FrameAcess to grab the frames of an avi, I cannot get it to output frames from the quicktime movie.
    The qicktime movie I am using plays fine within jmf (in fact it was generated by jmf) and it plays fine within the standard quicktime player.
    However, when I use the bufferToImage method on a quicktime movie, it always outputs a null image (I have tried various methods).
    I have provided my complete code (which has a hardcoded link to a quicktime file). Any ideas? Has anyone been able to do this? Perhaps I have a format error? Should jmf really be this confusing?
    Thanks,

    Andyble,
    Thanks for the suggestion. When I use your line, my Image is no longer null (and the resulting BufferedImage is not null either), but it outputs a "black" in the jpeg file. Any other ideas? What did you mean by a -1 F for the frame rate? Did you mean changing the format to a negative 1 frame rate? I tried that, but it did not seem to have any change. Can you let me know if I misunderstood that. Thanks.

  • ITunes/Quicktime will not open

    So iTunes 7.02 and whatever the latest quicktime is will not launch at all. If I launch them they'll show up in task manager, but will never open. Ending task does nothing but cause my comp to go completely unstable (won't shut down/reboot except with a hard shutdown, can't go to add/remove programs, explorer is f'd up and won't close and reopen itself, etc). Also, trying to launch either of them prevents me from opening new programs or shutting down.
    I've scoured the web and itunes support and haven't found a solution that works for me.
    So far I've...
    1)uninstalled itunes/quicktime, deleted all files (except for itunes preferences/playlists), rebooted and reinstalled.
    2)uninstalled itunes/quicktime, reboot, installed quicktime 6.4, reboot, unistalled quicktime, reboot, reinstalled itunes/quicktime 7+
    3)uninstalled itunes/quicktime, delete all itunes/quicktime files, reboot, installed quicktime standalone, installed itunes.
    4)uninstalled apple software updater, and redid #3.
    5) uninstalled quicktime and itunes, rebooted, removed itunes preference files from both application data folders, reinstalled.
    And tried some of the above a few more times.
    There were no hardware/software changes, this just started happening two days ago. Plugging in my shuffle will charge it but iTunes won't launch (except in task manager).
    I don't have Norton/McAffee (that was creating a problem for some people). I'm using windows firewall and it is already an exception. Current anti-virus is AVG 7.5, I have all the security updates including SP2.

    excellent news. glad you're up and running again.
    here's what was probably going on. since itunes and quicktime (and ituneshelper) are internet applications, your Firewall will be keeping an eye on modifications to those programs. typically a new set of rules is generated for the new versions of the applications. so it's possible for the Firewall to allow the earlier version of the application, but balk at the newer one (because there's different sets of rules for each one).
    so if you run into this sort of thing again after an upgrade, try checking through the exceptions that you firewall has set up for those new versions of the applications.
