Error 0x80040707

Initially had problems with itunes 5. I removed it but only had itunes 4.8. I wanted itunes 4.9 for Podcasts and reinstalled it form the download on this site. Now itunes wont open. get message that music library created by newer version.
When I try to remove itunes 4.9 using add/remove iget the above error followed by 'Acess Denied' which seems a bit harsh. I know others have posted simliar problem but have not seen that error code.

hi Nicholas!
My initail problem with itunes 5 was that it seemed to block internet access by interfering with the wireless router.
hmmmm. by any chance are you running either a BT Voyager 2100 or a D-link router?
for BT Voyager 2100, see:

keep us posted.

  • Error: 0x80040707 - Access Denied while installing itunes +ipod messed up

    Yesterday morning my ipod (nano) was working fine, and i plugged it in to upload music and it said something about installing a new version of itunes on my ipod. i clicked yes, and somewhere during installation i assume, it got unplugged by one of my family members wanting to use a USB outlet. well, it deleted everything on my ipod, and then it wouldnt recognize my ipod in itunes.
    i went to the site, did all the restore, restart, retry, crap until i got to reinstall. when i try to reinstall itunes, or remove "ipod for windows 01 -09-06" [not sure about that date] i get "Error: 0x80040707" in a popup window, then another saying "Access Denied"
    Before i tried to reinstall itunes, it still wouldnt recognize my ipod either. when i plugged it in, it would say "removable disk: f" like it was just a usb memory stick or something. i really have no idea what to do as i am new with the whole itunes stuff, and have previously used musicmatch.
    thanks

    Hi there...grrr...I always hate this type of error because sometimes it is problematic to fix.
    First off, remove iTunes and Quicktime and do a nice, fresh clean install. Save it to your harddrive and install it from there instead of running the installation over the internet.
    Also, try this as it has helped a few with this particular bug
    1. Run the setup program and PAY ATTENTION to the folder where you are installing the software. Keep clicking on the "Next" button and here it is, the progress bar.
    2. When the progress bar reaches 100% and you get the 0x80040707 error message, DO NOT click "Accept" or "Ok" or whatever says the button in the error window. Instead proceed as I describe:
    3. Go to the the folder where the program is supposed to be installed. Yes, it's there!. Copy this folder to another location (for example, to the desktop).
    4. Now click "Accept" or "Ok" in the 0x80040707 error window. This will erase almost every file in the folder where the program was originally installed. Who cares? You have a copy of it.
    5. Now overwrite this almost-empty original installation folder with the one you back-upped.
    6. If you want you can even create manually a shortcut of the EXE file that launches the software wherever you like. Double click it.
    Let me know if it helps. Anyone else with a suggestion, feel free to throw it out.

  • Itunes and qt not loading   +   can't uninstall qt - error 0x80040707 ...

    Hi,
    i've got a German Windows XP (home edition) Service Pack 2 with all Updates and can install itunes with qt without problems, but if i doubleklick on the itunes icon, nothing happens! The pc is loading a short time but stops then an nothings happens .... the same situation is, when i klick on *.mov files and if i want to start qt. I tried to uninstall and reinstall itunes but nothing changes (even if i try an older version of itunes). Then I tried to uninstall an reinstall QT, but when start the uninstallation of qt, there is an error (0x80040707 ... something with dll) and he shuts down the uninstallation, after I clicked yes when he askes me if I really want to uninstall QT.
    so please help me ... I was in this forum for hours the last days and read a lot of problems witch were similar to mine, but none of the advices helpt me (tried ad-aware, ewido and so on)
    PS: sorry for my bad english, I'm german...

    Tried opening Quicktime - same. Tried Quicktime settings from control panel - a Fatal error has occured.
    that corresponds to a "standalone 1603" error message on earlier versions of the itunes and quicktime installers.
    let's try this first.
    here's what we'll try first.
    Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:
    Description of the Windows Installer CleanUp Utility
    Next, we’ll manually remove leftover program files and folders.
    1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
    2. In My Computer, open Local Disk.
    3. Open Program Files.
    4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
    5. Navigate to C:\Windows\system32\.
    6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
    7. Restart your computer.
    once we've got all the existing QuickTime scraped away, let's try a careful standalone QT 7.1.3 reinstall.
    download and save a copy of the QT 7.1.3 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
    Quicktime 7.1.3 Installers … get the one that doesn’t mention itunes
    if that install goes through okay, reboot the PC and try another itunes install. does that go through okay this time?
    (if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)

    Can anyone help??

    hiya!
    okay, in this context the 0x80040707 (citing the QuickTimeUnInstallProc) usually indicates that the installation configuration information for the QT on your PC has been corrupted.
    download and install the Windows Installer Cleanup utility, and use it to clear away any existing QuickTime installation configuration information:

    once we've got the old QT scraped out of there, we'll try another standalone QT 7.0.4 install, taking a few additional explicit precautions.
    download and save a copy of the standalone QT installer to your hard drive. (we'll run the install from there rather than online.) switch off all antivirus and antispyware applications prior to the install.

    I was able to solve this, but I had to uninstall all instances of iTunes, ipod and QuickTime, delete their directories, use http://support.microsoft.com/kb/290301/
    to delete the installations of each and then use msconfig to remove them from the Startup.
    After that I rebooted and did a new install with the QuickTime Stand Alone and it worked!

    One thing that rather jumps to my attention is the mention of AVG. That is the anti-virus program, right?

    can ANYONE help me with this one. Ive just bought an iPod Nano and have tried to install the cd. It tries to go through the process but then i get this error message.
    Its really irritating cause i have searched the internet for this error and can not seem to find a solution.
    From a few sites ive been on it looks like it might be the Service Pack I have on XP. I have SP1 and i read that i need SP2 to run itunes. Is this correct?
    Any help would be VERY much appreciated.
    Yvonne

    hi thank u for ur reply. i have gone to windows update and it gives me a list of things that can be updated. It mentions service pack 1 but does not say that it will update to service pack 2. Is this something that can be definitly done or does it depend on how old or updated the computer is?

  • "iTunes has encountered an error and has to close"

    I'm getting this error message whenever I plug in my nano or my mini. iTunes crashes. This just started happening. So far I've reset, restored, reinstalled - you name it. But nothing works.
    iTunes works fine when there's no iPod plugged in.
    Help?

    well done MAJR!
    just a note on the error message "itunes has encountered a problem and needs to close".
    there are actually at least three different contexts in which people get this message, and the treatments will differ depending on the context. here's some info on the three most common contexts.
    "itunes has encountered a problem ..." when LAUNCHING ITUNES
    this is the most common time to see the message. in my experience, 90% of the time this is caused by a broken QuickTime 7.0.x. So the first thing people should check for is whether their Quicktime will launch, or whether it gives them an error message when they try to launch it.
    if you get an error message when you try to launch Quicktime, the standard treatment is to swap out your QuickTime. there's actually an Apple KB doc on the problem, although the silly sausages have given the error message incorrectly in the doc (as of the 23 December 2005 revision), which makes it more difficult to find the message when you're searching for it:
    iTunes 6 for Windows unexpectedly quits when opened
    ... that method is pretty servicable in the majority of cases, but it leaves you open to a known complication of a broken Quicktime where people can't uninstall their QT and get an error message citing their QuickTime "uninstall.log". so i usually suggest to people that they try a careful standalone QT 7.0.4 reinstall instead (which gets past the "uninstall.log" error):
    download and save a copy of the QT 7.0.4 installer to your hard drive. (run the install from there rather than online.) switch off all antivirus and antispyware applications prior to the install.
    Quicktime 7.0.4 Standalone Installer
    known complications of QuickTime reinstalls: the most common (for QT versions 7.0.2 and 7.0.3 and iTunes versions 5.0.0.35 through 6.0.1.3, at least) is an error message citing "Error 0x80040707". in this context (again, the treatments for this error message are context dependent too), the most common cause of the Error 0x80040707 is a snarlup in the QT installation registry entries.
    what typically fixes it is the Windows Installer CleanUp utility:
    Description of the Windows Installer CleanUp Utility
    use the utility to clear the existing Quicktime entries. then try the careful standalone QT 7.0.4 reinstall again.
    other known causes of "itunes has encountered a problem ..." on launch: probably the most common of the rarer causes (if you'll pardon the oxymoron) is a rare weird problem to do with the registry and user accounts on XP machines.
    to check for that, first head into your "User Accounts" control panel and create a new user account with full administrative privileges. (there's help documentation on how to do that at the left of the control panel screen.) while you're in that control panel, switch off "Fast User Switching" in your logging-on preferences.
    now, log out of the old account and log into the new account. can you get itunes to launch inside the new account?
    if itunes does launch inside the new account, then try an experiment (this rules out an ultra-rare "false positive diagnosis" of the registry/user-account thing). use the following technique to share the music from your old account to the new account:
    iTunes: How to share music between different accounts on a single computer
    if itunes still launches from the new account once you've shared the music from the old account to the new account, then you've got the registry/user-account thing.
    fixing the old account might be tricky. we've had mixed success with combinations of complete uninstalls of itunes using the following technique:
    Da Gopha: Stepwise clean uninstallation of iTunes
    ... followed by application of a Registry repair program such as RegCleaner or Registry Fix. failing that, it might be worth just "moving house" to the new account.
    (there are other even rarer causes of this message on launch ... if you believe you've got one of those, best to start your own thread and explicitly explain as best as you can what the behavior is and what steps you've already taken to try to resolve the issue.
    "itunes has encountered a problem ..." when IMPORTING A CD
    in iTunes versions 4.9 through 6.0.1.3 this was most commonly caused by a hyperthreading problem on PCs with dual cores and dual processors. on those versions of iTunes, the workaround was to set the itunes affinity to a single core/processor. (Otto42 is our authority on that topic.) but the bug has been fixed in iTunes 6.0.2:
    iTunes for Windows quits unexpectedly importing CDs on a dual-processor or dual-core computer
    "itunes has encountered a problem ..." when PLUGGING IN AN IPOD
    the most mysterious of the three main classes. there doesn't seem to be a common cause of this one (or at least it hasn't been clearly identified yet).
    probably the first things to check up on are:
    iTunes for Windows may unexpectedly quit when syncing folders of pictures with iPod
    ... but if no joy there, this is probably the best next port of call:
    Troubleshooting an unexpected quit or restart of Windows, iTunes, or QuickTime

  • Is the text associated with "0x80040707" significant?

    hi y'all
    i've seen two posts today about errors referencing "0x80040707". but the
    b text
    associated with each error message is different.
    i've also seen a fix (involving editing the registry) that references the "0x80040707" number. but the fix is for an "0x80040707" error associated with text that is different
    b again
    from the two posts ...
    because i'm not sure whether or not the different texts imply there's a different problem in the three cases, i'm
    b really
    reluctant at this point to direct people to the fix.
    would anybody knowledgeable mind commenting on the significance that the various associated texts have to these "0x80040707" errors? In particular, do you have to do a different fix for each different "associated text"?
    love, b

    b case study of a fix for "Internal Failure, error number 0x80040707" variation:
    Let me see if I can recall the exact order of what we did. First I went into "Run", msconfig. Then in the general tab, chose Selective startup. Then I clicked on the start up tab and deselected everything but I tunes. Then we went back to add/remove software and tried to delete the old I tunes.
    I was not able to delete the I tunes (still got the same internal error 0x80040707). At that point we logged into my son's user account in windows and tried to remove i-tunes through control panel add/remove. It did delete! The problem was that my son had down loaded the first i tunes and each of our user accounts acts as administrator, so I tunes could only be deleted by the administrator that down loaded it. Once I was able to delete the old, we down loaded the new 4.9 without problem.
    I had not realized the importance of the diffent users within windows xp. Now I know

  • Internal failure 0x80040707 access denied

    Sorry to bring up an old topic problem, but the search turns up posts dating back to 2004 and the links do not work. Anyway...
    I get an "internal failure 0x80040707 access denied" upon loading iTunes and QuickTime after the required reboot either with the CD or with the downloaded versions from the web.
    I did not connect the Ipod to the computer until after the software was installed.
    I have tried all the below with Norton Antivirus disabled:
    1) upgraded XP Pro from SP1 to SP2.
    2) installed and uninstalled iTunes and QuickTime many, many, many, many times, using the uninstaller and the Windows Install Clean Up downloaded from
    http://consumer.installshield.com/kb.asp?id=Q108322
    and using task manager to remove remnants (qttask.exe, ip*, qt*).
    3) followed the instructions at
    http://consumer.installshield.com/kb.asp?id=Q108167
    there were no problems with the registry.
    4) installed only the iPod updater and not installed iTunes and QuickTme from the CD (nothing works, but I still get the error message on reboot.
    5) deleted the folder containing iPod and QuickTime after an unsuccessful install.
    iTunes runs after the reboot, but in preferences it says no iPod is connected when it is connected. The iPod when connected to the 'puter says "Do not disconnect" with a spinning "sun" in the upper left hand corner. The do not disconnect never goes away, even after leaving it alone overnight.
    Windows knows the Ipod is connected to a USB port and says it is "working normally."
    QuickTime will play "stuff."
    I spent 40 minutes on the phone with Best Buy who said to call Apple. I spent 20 minutes on the phone with Apple who said call Dell. I Spent 15 minutes on a chat with a Dell tech who ended the conversation with out giving me any help (was goin' home time for him).
    I've probably got about 30 hours into this and my kid is wondering when her iPod will work.
    Any advice or pointers?
    Thanks for any suggestions!!!

    I don't know how to do this as the message occurs when I reboot and before my desktop icons are loaded. The first window that appears is the InstallShield completing the software load, I guess. Then the "internal failure error 0x80040707" window appears. At that point my only choice is to click "OK" or "X" on the Internal falure window. After that disappears the "access denied" window pops up. The Taskbar is not loaded either.

  • Hard disk wiped, and now I cant re-load my ipod software

    I got a new graphics card and my mum stuffed it when she tried to install it. We got it done professionally but they had to re-set my computer. we paid extra to have them transfer all my programs and documents to another computer and transfer them back. It didnt work, I lost everything except any folders on my desktop (weird huh). Anyway, I lost itunes, quicktime and my ipod software. I tried to re-load it(using the cd) onto my computer but it comes up with a window saying "error: 0x80040707" "access is denied". I used my cd and loaded it onto my sisters computer fine and Im wondering what went wrong. After that I tried downloading itunes from the apple site and even though it says its installed, when I open it it comes up with the message 'itunes has encountered a problem and needs to close' straight away, without even opening itunes.
    Im not having a problem with any other software and I dont know what to do about it.
    Aside from that I lost some very important photos when my computer was wiped. I still have them on my ipod and I cannot get them off. It says I have a thumbs folder and a photo database file. How do I get the photos off, especiallyy since I cant seem to get itunes back

    okay, that version of the 0x80040707 is a known complication of a broken QuickTime. in this context, it usually means the installation configuration information of the QuickTime has been compromised.
    here's what we'll try first.
    Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:

    next use the QuickTime component of the complete uninstall instructions in the following document as a guide to a manual removal of leftover QuickTime program files and folders.

    once we've got all the existing QuickTime scraped away, let's try another careful standalone QT 7.0.4 reinstall.
    does it go through properly this time? if so, does your itunes launch properly again?

  • A big THANK YOU to B. NOIR! because...

    I just experienced my first "iTunes has encountered an error and needs to close" warning!, when I booted up my machine this morning and tried to launch iTunes. I tried and tried to coax iTunes to open but I wasn't successful! Next, I decided to back up my iTunes library--it' been about two weeks since I last did this and I've purchased a number of new tunes in the meantime, plus I endured the iTunes Plus upgrade in the interim. All of this was worth trying to save!
    Then, I tried a few times to launch iTunes, but dang it--iTunes refused to open. Thanks to reading the many helpful posts by b. noir I knew right away Quick Time was probably the culprit. Sure enough--I tried to open Quicktime independently and it caused an error.
    I solved my problem by opening my Add/Remove Programs folder and "changing" (i.e. repairing) Quicktime. (I first tried to do this with my Norton program active and the fixes failed! The next time I tried, I turned off my virus protection and my firewall, then things seemed to work correctly.)
    However, please know that I did have to reboot my computer before the corrections took effect!
    Now, all is well and iTunes works fine again!
    Anyway, this is a big shoutout to b. noir for helping me find the solution from all of his forum posts. I didn't even have to ask a question in the forums, I already knew what the answer would be! And, it was the correct answer!
    Thank you "b. noir" and all of the other helpful volunteers on this site! I would not have known how to solve this problem so quickly otherwise. In fact, I'm sure I would have spent the bulk of this day trying to get iTunes to open.

    known complications of QuickTime reinstalls: the most common (for QT versions 7.0.2 and 7.0.3 and iTunes versions 5.0.0.35 through 6.0.1.3, at least) is an error message citing "Error 0x80040707". in this context (again, the treatments for this error message are context dependent too), the most common cause of the Error 0x80040707 is a snarlup in the QT installation registry entries.
    what typically fixes it is the Windows Installer CleanUp utility:
    Description of the Windows Installer CleanUp Utility
    use the utility to clear the existing Quicktime entries. then try the careful standalone QT 7.0.4 reinstall again.
    other known causes of "itunes has encountered a problem ..." on launch: probably the most common of the rarer causes (if you'll pardon the oxymoron) is a rare weird problem to do with the registry and user accounts on XP machines.
    to check for that, first head into your "User Accounts" control panel and create a new user account with full administrative privileges. (there's help documentation on how to do that at the left of the control panel screen.) while you're in that control panel, switch off "Fast User Switching" in your logging-on preferences.
    now, log out of the old account and log into the new account. can you get itunes to launch inside the new account?
    if itunes does launch inside the new account, then try an experiment (this rules out an ultra-rare "false positive diagnosis" of the registry/user-account thing). use the following technique to share the music from your old account to the new account:
    iTunes: How to share music between different accounts on a single computer
    if itunes still launches from the new account once you've shared the music from the old account to the new account, then you've got the registry/user-account thing.
    fixing the old account might be tricky. we've had mixed success with combinations of complete uninstalls of itunes using the following technique:
    Da Gopha: Stepwise clean uninstallation of iTunes
    ... followed by application of a Registry repair program such as RegCleaner or Registry Fix. failing that, it might be worth just "moving house" to the new account.
    (there are other even rarer causes of this message on launch ... if you believe you've got one of those, best to start your own thread and explicitly explain as best as you can what the behavior is and what steps you've already taken to try to resolve the issue.
    "itunes has encountered a problem ..." when IMPORTING A CD
    in iTunes versions 4.9 through 6.0.1.3 this was most commonly caused by a hyperthreading problem on PCs with dual cores and dual processors. on those versions of iTunes, the workaround was to set the itunes affinity to a single core/processor. (Otto42 is our authority on that topic.) but the bug has been fixed in iTunes 6.0.2:
    iTunes for Windows quits unexpectedly importing CDs on a dual-processor or dual-core computer
    "itunes has encountered a problem ..." when PLUGGING IN AN IPOD
    the most mysterious of the three main classes. there doesn't seem to be a common cause of this one (or at least it hasn't been clearly identified yet).
    probably the first things to check up on are:
    iTunes for Windows may unexpectedly quit when syncing folders of pictures with iPod
    ... but if no joy there, this is probably the best next port of call:
    Troubleshooting an unexpected quit or restart of Windows, iTunes, or QuickTime
