ITunes Error Message required files are missing - can't run

Plugged my iPod Nano in and my iTunes gives error "iTunes cannot run because some of its required files are missing.  Please reinstall iTunes".  Tried to reinstall iTunes and get same error. 

Old question. I solved the problem myself.

  • Tried loading the latest version of itunes but the download would not complete. Now when I connect my phone to a usb i get an error stating required files are missing, reinstall itunes. I tried that but the reinstall keeps timing out?

    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 the page in case one of them applies.
    The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with QuickTime or third party software.
    Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

  • ITunes post-upgrade: "Required files are missing"

    I just went through the process to install the latest upgrade, but there was some sort of problem with the installer. Rather than installing the upgrade, it apparently just deleted important files and then failed before replacing them. Now when I try to launch the program I get the message "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
    Here's my question: If I download and reinstall iTunes, will the installer be smart enough to recognize and preserve the good files that remain? I want to solve this in a manner that will maintain all my settings and file associations. Any help would be great.

    It would be great if I could get an answer on this. As stated in the previous post, my iTunes will not start due to missing files from a botched update. Furthermore, when I downloaded the latest version to reinstall, it did not appear to recognize my previous installation.
    Is there a way to automatically or manually repair the problem? Can I copy certain current files and replace them once I've reinstalled?

  • Unable to open iTunes...Required files are missing

    Windows XP User - just downloaded 7.5 and received the above message. Reinstalled and received same error. Any ideas?
    Thanking you in advance

    Hey... I had the same problem! In one of the other forums, they suggested uninstalling Quicktime player and reinstalling it. The downloading from here
    www.apple.com/support/downlods/quicktime72forwindows.html
    and then launch iTunes... it worked for me just a few mins ago!
    Good luck!

  • Need help deleting CS4 when getting error: Required Files are missing

    Trying to delete CS4 off my computer.
    The uninstaller will not launch on any program - I'm getting an error saying required files are missing to launch the programs.
    Anyone know a work around? I know I can drag some files from Applications to the trash, but I want to get everything in all the areas of the computer since I'm trying to reclaim used HD storage.  I'm on a Macbook, OS 10.10.2
    Thanks,
    Scott

    Irrelevant. Your install never worked right in the first place after upgrading to 10.10.. Simply trash the files.

  • ERROR - "iTunes cannot run because some of its required files are missing."

    Every time I open iTunes I'm getting the following error:
    "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
    This started after I installed iTunes 8.0.2.20 on my PC (running Windows XP SP3) to get the latest version after purchasing an iPhone.
    I've tried uninstalling, reinstalling, & fixing iTunes. I've also tried uninstalling & reinstalling Quicktime using versions 7.3.1.70 & 7.55.90.70. With 7.3.1.70 installed I got an error stating something like iTunes 8.0.2.20 is only compatible Quicktime 7.55.90.70 & to reinstall iTunes.
    No matter what I do the same error message appears whenever I try to access iTunes.
    I can get into iTunes immediately after an install if I remove Quicktime & clean my Windows registry but if I then close iTunes & reopen it I get the missing file error.
    I'm not having this problem with my wife's PC running Vista & iTunes 8.0.2.20.
    This is starting to get VERY frustrating. Please, if anyone can help I would GREATLY appreciate it.

    Seriously ***!!!
    I thought I hit some gold with this:

    I picked up Revo Uninstaller per the above directions here:
    http://www.download.com/Revo-Uninstaller/3000-2096_4-10687648.html
    & proceeded setting to work cleaning out the complete Apple suite as directed. 5 hours later, after downloading a brand new copy of iTunes, & having supposedly removed all traces of anything Apple, I'm right back where I was, getting the same "required files are missing" error!
    I've got a $300 iPhone that I can't use properly because their software won't play nice.
    Like I said at the beginning of this post ***! Now I'm beginning to move from agitated to flat out angry! >:-(
    Does ANYONE know what else I can try, or if there is a phone number I can call to get some technical support from Apple?

  • ITunes can not run because some required files are missing.

    I got a message that said something like "iTunes can not run because some required files are missing. reinstall itunes." I tried to reinstall iTunes but I kept getting that message. So, i uninstalled it, and tried to install it again. this did not work. I think that Quicktime is actually what is broken, because iTunes installs fine, but the Quicktime installation failed. When the installation failed, i got a message that said, "Installation failed: error code: -3"
    I then tried installing Quicktime with the standalone installer. The installation got further, but it then failed as well, giving the error code -1603.
    What can I do to get this reinstalled, and if you can't answer that, how can I contact Apple from Iraq? Thank you.

    hmmm...that happened to me at one point to, and I'm trying to think back, I believe I was able to uninstall it by using the standalone installer.....
    Try these steps and see if anything helps, and then in the troubleshooting section, look up the specific error number you are receiving...

  • Itunes can't run because some of its required files are missing.

    I've been having this problem for 2 weeks now, Every time I tried opening Itunes it would say Itunes can't run because some of its required files are missing. Please reinstall Itunes. Well I've reinstalled it a number of its and it kept giving me the same error message. Then I found a program Revo Uninstaller and I got everything dealing with Itunes and apple off of the computer and then reinstalled it. It worked but once the program was closed it wouldn't open back up and gave me the same error message. Any ideas?

    Hey jrdeac,
    That sounds frustrating! Let's do a full uninstall of iTunes and all related components, then reinstall. The following article explains how to do so for your operating system:
    Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
    http://support.apple.com/kb/HT1925
    Note: It is important to remove all of the listed software, in order. Uninstalling these components in a different order, or only uninstalling some of these components may have unintended effects.
    If the issue persists after completely removing, and reinstalling, please see the following article:
    iTunes for Windows XP: Troubleshooting unexpected quits, freezes, or launch issues

  • Recently updated itunes to (10.22.14) when attempting to open itunes, it fails to open and I get this message: itunes cannot run because some of its required files are missing. Please reinstall itunes.

    Just updated itunes to (10.22.14) and itunes won't open. I get message: Itunes cannot run because some of its required files are missing. Please reinstall itunes. Is there any other way to troubleshoot this other than reinstalling itunes?

    With that one in that context, I think we should check for malware.
    Try downloading and installing the free version of Malwarebytes AntiMalware. Update your MBAM definitions and then run a full scan of the PC. (Takes about 2 hour on my Lenovo.)
    http://www.malwarebytes.org/mbam.php
    Does the scan find any infections? If so, please paste the contents of the log file for the scan in a reply here so we can have a look.

    Follow these instructions to completely remove Apple software
    http://support.apple.com/kb/HT1923
    Then use free Ccleaner to repeatly repair your registry until it's fixed.

    download iTunes again from Apple.

    If you have 64bit Vista or Windows 7, look for the seperate download of iTunes for that further down the page.
    Once installed, use the Apple Software Update under your Start Menu to fully update all Apple components.
    Your content will remain on the drive in the Music > iTunes Folder, nothing is deleted.
    You should be making backups of your content regularly, either through iTunes or via copying the iTunesFolder in your Music folder to a external drive.
    Windows is notorious for having "other" issues that make it unstable, we as volunteers helping others can't always resolve those issues.

    You should first uninstall iTunes completely.
    This is not an easy task!
    Read this article on how to remove iTunes completely

    Then download the latest version of iTunes for your Windows Version and install it.

    HI daddio,
    Ok some things first I need to know...Did you use Microsoft cleanup utility to clean up all those uninstalls you have done?
    I hate Norton and anyone who reads my posts will know that. I have seen way too many infected PC's by Norton users. Did you try the EWIDO and AdAware scan? I see you said you read lots of posts. That is helping folks remove the malware in order to get iTunes and quicktime back to health.

  • I'm getting a message that says itunes cannot run b/c some required files are missing.  Please reinstall itunes.  I'm scared to, I don't want it to replace my current itunes and lose all my music!

    Reinstalling iTunes simply replaces the application.  It shouldn't affect your media.  You do have backups, right?
