Unknown error 0x666D743F I'd really like iTunes to open now!!!

I know I'm not the first to experience this one...
I cured it by installing iTunes 6 instead, then realised I can't run my new Nano on anything other than 7. I've tried the things suggested in the article http://docs.info.apple.com/article.html?artnum=304318 and they didn't work - found another couple of suggestions on the discussion board and they didn't work either.
I'm stuck with a Dell running Windows 2000 - I realise neither are the ultimate piece of kit but I have to make do with what I've got! I've run Ad-Aware and uninstalled my Kodak software to tackle the obvious bugs.
Please can anyone make any other suggestions as to how to overcome this?
Thanks very muchly!

It posts that exact message?
Perhaps you would post a bit more info?
What is the exact message you see?
Which version of iTunes?
Which version of Mac OS?
Does iTunes work fine without connecting the iPod?
Which iPod do you have? Which firmware on the iPod?

  • Get unknown error 0x666D743F trying to start Itunes 7 on remote desktop

    Hi gang,
    I just updated to ITunes 7 and I'm getting an unknown error 0x666D743F using the Microsoft Remote Desktop. ITunes 7 will work when I login direct to the PC console. The worked fine with several versions of ITunes up through 6.
    Any ideas on hwo to fix this?
    Thanks,

    Hey,
    I was trying to debug some sound problems with iTunes 7 when I ran into this myself. I was messing around in start->control panel->sound->volume->advanced->performance. If I set hardware acceleration to none I'd get the exact error code youre talking about, if I set it to basic my audio quality was OK, if I set it to anything higher than basic iTunes would open but the sound problems were terrible. In any case I suggest you go check and see what your hardware acceleration level is. If it's basic maybe thats the reason your iTunes can't start. Just an idea, hopefully it helps.
    Take care.

  • Unknown Error 4300, cannot burn disk in iTunes

    Good morning,
    I am having the problem of not being able to burn a disc in iTunes. I am getting the message of unknown error (4300). It acts like it's burning then I get that message.
    I have did set the properties in my computer to burn audio disk and also unchecked includ cd text in iTunes in the burn options as suggested on another thread.
    Any other suggestions?
    TIA,
    Blondie

    Hey there,
    I am also having the same problem. I recently upgraded my system from an AMD Athlon 64 X2 Dual-Core 3800+ and Asus A8N-E motherboard to an Intel Core-Duo E8400 and Asus P5Q motherboard. The DVD drive, an LG GSA 4167b, is the same. iTunes itself runs much smoother now, but for some reason will not burn CDs (unknown error 4300). This is curious, as I have burned many CDs with this drive using iTunes on my old system. I have tried uninstalling and reinstalling as well as removing and old version (4) of a Nero Suite I had kicking around. I cannot seem to find a list of iTunes error codes anywhere and there does not seem to be any real answers to this error code. Yes, the drive is plugged in properly (sATA)
    thanks very much!

  • Unknown error -3212. I updated to iTunes 11.4.  I can no longer connect to the Store.

    I updated to iTunes 11.4 when prompted.  I can no longer connect to the Store.  Tried all troubleshooting, checked Firewall, and my internet connection is fine.  I re-downloaded iTunes and selected the "repair" radio button.  Still has not resolved "unknown error occurred (-3212)".  Does anyone have any other suggestions?

    Hey there ILSquid,
    It sounds like you have checked your firewall settings, and your internet connection but cannot get to the iTunes Store with your iTunes application and you get this error number 3212. I would look over the troubleshooting in the following article to see what steps have yet to be done. Infact I would recommend doing the troubleshooting sequentially from top to bottom.

    If you still cannot get to the iTunes Store there is a more advanced troubleshooting article with more to try, here:

  • Unknown error [0x666D743F]

    I recently downloaded iTunes 7 on my Tablet PC [Toshiba]. Installed it without problem but when I now click the iTunes icon, I get the following message:
    'The iTunes application cannot be opened. An unknown error ocurred [0x666D743F]'
    I had previously uninstalled both iTunes 6 and Quicktime 7 before installing iTunes 7. I had also tried unistalling iTunes 7 and deleting all references to it on the c drive but same error on reinstallation of iTune 7.
    Incidentally, iTunes 6 works fine or reinstallation!
    Could anyone, please, explain to me what to do next?

    there's a few different things causing that. here's a couple of the more common ones, just to start off investigations:
    That error has been known to be produced by having Total Recorder or the Volume Logic plug-in installed on the PC.
    For a workaround for Total Recorder, see:

  • I get an unknown error (-50) when downloading movies from iTunes

    When I download a movie or TV show from iTunes, it starts downloading like normal, then the "time remaining" starts ticking up rapidly. Sometimes it keeps downloading, and then starts over suddenly, but eventually it always leads me to the (-50) unknown error. It also charges me for the movie/TV show. Any ideas how to fix it?

    I have a 30g Video Ipod and I have been having
    problems with it trying to syn up. I downloaded the
    Vista update for it and still no syncing but when I
    tried to update the Ipod I got this message.
    Ipod cannot be updated. An unknown error occured
    (-50).
    If anyone knows what this means and possibly could
    give me help with it, I would appreciate it very much.
    Same thing happened to me last night. It was right after I DL the update given by apple for Windows Vista. I just closed everything restarted my computer and tried again and it worked. Just that now all my Album Artwork is messed up. I'm listening to Fall Out Boy and I get the artwork for Grey's Anatomy Podcast. Weird. I have no idea how to fix it either.

  • Getting an "unknown error' when trying to sign into iTunes Store

    When I try to sign into the iTunes store, it is giving me an "Unknown Error" message, without an error code or anything. I have tried restarting the computer and that didn't help. Any ideas on how to fix this issue?
    Windows 8
    iTunes 11
    Thanks

    I received this email from Apple and this corrected the problem for me...  I only had to reset the iTunes cache
    1) Open iTunes
    2) At the top menu, click File > Preferences (iTunes > Preferences on a Mac)
    3) In the Preferences menu, click the Advanced tab
    4) In the Advanced menu, you should see a button that says "Reset Cache". Please click this button.

  • Unknown error when trying to sync from itunes to ipod

    Does anyone know what the problem is? Everytime I try to sync music onto my 4GB ipod nano, a message pops up saying:
    Attempting to copy to the disk [ipod name] failed. An unknown error occured (-54).
    I can't seem to figure out what is wrong. I restored my ipod and reset my ipod, but I still don't know what is wrong.

    Thanks for you suggestion roaminggnome. I tried typing in 13019 like you said and it gave me a few options to try and fix it but none of them worked (of course). I fiddled around with it for a while some more on my own and some how got it to work again, lol. Thanks again though for offering a solution.

  • Unknown error -3212 when attempting to access iTunes Store (Windows 7)

    This apparently is a firewall problem. I'm running Norton 360 on Windows 7 Home Premium SP1. I managed to solve the problem by going into Security>Manage Firewall>Program Rules, scrolling down to iTunes and setting the the Access level. Apparently Norton 360 occasionally (not always?) resets itself to "Auto" when a new iTunes update is installed. I reset it to "Allow" and access to the iTunes Store is restored.

  • TS1424 I am having issues downloading music from iTunes, it comes up saying an unknown error has occurred - please check your network connection. Now I can connect to iTunes store and have itunes as an exception for downloads so don't know what else to do

    Hello, I've started having an issue downloading songs and apps from iTunes to our PC which has Windows XP Professional installed. We also use Karspersky Anti-Virus and Firefox as an internet browser. Have never had this issue before, it comes up with "An unknow error has occured and downloads are stopped with an error 8003. Also says please check your network connection" We have no issue connecting to iTunes store or the network so not sure how to fix this. It is very frustrating. Have checked Windows Firewall and iTunes is an exception, can't think of anything else why it won't work.

    I sounds as though you need to start again. The following article tells you how to completely remove iTunes and Quicktime. If you didn't actually install iTunes you wont find it in add/remove programs so you can't do that bit, but still delete the iTunes folder in Program Files as advised in the article.
    http://docs.info.apple.com/article.html?artnum=93698
    Once you have got rid of them, try installing the latest version of iTunes. There is a link to it in the article.
    Itunes wont move your music for you, get iTune sgoing then ask again.

  • I have been getting the message Unknown error 0xE000024 whenever I get into iTunes to look at my ipod to restore it because it freezes every time I try to unlock it. What does this mean, and what can I do?

    Help please

    Now it keeps saying that it is restored but there is still no music or video on it. And a new error is coming up that says "We could not complete your iTunes store request.The iTunes Store is temporarily unavailable. Please try again later."
