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?

    "iTunes cannot run because some of its required files are missing." Help!!
    Hello everyone, I have looked throughout this forum but couldn’t find anything similar so I am posting this in the hope of someone helping me out.
    I have encountered some problems with iTunes (most recent edition) after doing a Dell update which seems to have knocked something out with iTunes.
    Whenever I hit the iTunes icon it refuses to run and iTunes displays the following message:-
    "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
    I don’t want to reinstall itunes from fresh as this will mean losing all the records and playlists that I have spent the last 3 years using.
    I first want to try by getting my old one back by any means neccessary.
    Like I said this problem first happened after a standard Dell update.
    I do have the option of doing a restore with the Dell or using Windows Vista restore itself but I fear I do not have enough disk space.
    On the Dell update I can restore to settings of a previous date which might bring iTunes back but when attempt to do
    that I keep getting the following message,
    "Not enough free disk space to back up"
    Around this time I am given a lists of what will be backed up and this readsas follows:-
    Pics 2.87gb
    Music 71.72gb
    Videos 330.57mb
    Documents 219.11mb
    Email etc 203.64mb
    How do I free up disk space to do the back up? An external hard drive?? If I baIs there anyway of getting a previous version of iTunes back?
    My drive information is as follows:-
    C Drive: Very little room - red warning - 5.67gb of 138gb
    D Drive: 6.34gb of 9.99 free
    Do I have too much music?
    Ideally don't want to reinstall itunes as is a ball ache, and it has all the playlists etc so if there is
    a way of restoring and getting back iTunes either via restoring system to the prior date when iTunes was ok.
    C drive is really full now. How can I clean this up and make more room? Do I need to add memory? Are all the songs
    causing the problem? What advise can you give me? Please help.
    Thanks!

    Nodders:
    I've recently had exactly the same message as you, after iTunes updated to 10.1.1.4. First of all, I checked the *My Music* folder to make sure it was still there - it was. (I do have a back up of that folder anyway!)
    I then chose the re-install iTunes option and a pop-up box asked if I wanted to uninstall iTunes or repair it. I (obviously) chose repair and I'm pretty sure what happened was that the install process simply re-installed a damaged (or missing) file. It far too quick to be a fresh install. My library was intact.
    So my advice(for what it's worth) is take the re-install option and then repair option. I can't guarantee anything, but ...
    By the way, after I experienced a recent hard drive failure, I decided to invest in a 1TB external drive to back up my iTunes library and personal files because it's a much easier way of backing up than my previous method. Luckily, I only lost a small recent part of my library, but it taught me a lesson. Back up regurlarly, using a larger hard drive than you are using on your computer (which allows you to keep the most recent and +next most recent+ back-ups, and don't rely on Windows to do the backing up. Find a suitable backup piece of software. (My hard drive came with s/w built in.)

    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.

  • 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 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?

    2: Next follow this Apple document to un-install iTunes

  • ITunes 10.6.1.7: "iTunes cannot run because some of its required files are missing. Please reinstall iTunes." ?

    Fakt:
    iTunes 10.6.1.7 Fehlermeldung: "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
    Jeder Versuch iTunes zu starten war bisher vergeblich: unter anderem auch das Vorgehen nach Artikel HT1925 der knowledge base.
    Frage:
    Windows XP Neuinstallation und/oder Installation einer älteren iTunes-Version als letzter Ausweg?

    Antwort und Lösung eine Woche später:
    Deinstallation und Neuinstallation von iTunes 10.6.1.7 produziert dieselbe Fehlermeldung.
    Es hilft nur eine Reparatur von iTunes unter Systemsteuerung / Software. Allerdings muss hier Windows XP mit Hilfe von Ausführen / msconfig im benutzerdefinierten Modus erneut gestartet werden - ohne APSDaemon, Avira und Skype zu laden!
    Die Fehlermeldung unterblieb, die Reparatur schritt voran, meldete Erfolg und benannte eine wohl defekte Datenenbank unter C:\Documents and Settings\MyAccountName\My Documents\My Music\iTunes um in:

  • ITunes cannot run because some of its required files are missing.....

    "iTunes cannot run because some of its required files are missing. Please reinstall iTunes."
    Is the error message I receive when trying to launch iTunes or updating my iPod.
    I have tried uninstalling both iTunes and qtime, restarting, installing with the iTunes75Setup.exe found on the iTunes download page from apple.com.
    To help narrow the issue, during install/uninstall/repair this error also occurs as it is "Registering iTunes automation server"
    any suggestion on how to resolve this issue would be great

    First uninstall Quicktime 7.3 only in control panel. Then download Quicktime 7.2 from http://www.apple.com/support/downloads/quicktimeforwindows.html. Hopefully it works for you because it worked for mine.

  • ITunes cannot run because some of its required files are missing.  How

    I have tried the "repair" option to fix my "iTunes cannot run because some of its required files are missing error message."  No luck.  I have rebooted.  No luck.  I am afraid to reinstall iTunes.  I have already lost my music once when I fried my computer.  I don't want to have to purchase my music AGAIN.  Is this really the only way to fix this?  Do I have to uninstall before I re-install?

    There are a few ways to fix this. For me, going to add/remove programs and then clicking on itunes, CHANGE, then REPAIR worked. I was also getting an issue that after a few days or a reboot, it would kill itself again..
    Others have to completely uninstall itunes and quicktime, erase their program files directories, then reinstall quicktiem first then itunes.
    Others have to uninstall itunes, go to internet explorer and clear the recent downloads and the cache, then close ie, redownload, and then install itunes.
    Good luck!

    When I try to open iTunes, it stalls for a few seconds and than a message pops up saying "iTunes cannot run because some of its required files are missing. Please reinstall iTunes." I have tried both reinstalling and repairing iTunes via putting in the disk that came with my iPOd but neither have helped. Please help.

  • "iTunes cannot run because some of it required files are missing."

    I first plugged in my iTouch to update and got an error message. Close iTunes and tried to re-open and got that error message: "iTunes cannot run because some of it required files are missing. Please reinstall iTunes." Obviously tried uninstalling and reinstalling and repairing. Also tried uninstalling and reinstalling Quicktime by itself no luck. Not sure what happened, hopefully this can be fixed quick.
    Thanks,

    Close iTunes and tried to re-open and got that error message: "iTunes cannot run because some of it required files are missing. Please reinstall iTunes."
    I don't like that one on modern versions of iTunes. If files *really were* missing, the modern versions would be much more likely to attempt to do a repair install of themselves when you went to launch them.
    We'd better check for malware. (I've seen this crop up for at least one chap in the context of a Backdoor.Bot infection.)
    Download and install the free version of Malwarebytes. Update your Malwarebytes definitions and then run a full scan.
    http://www.malwarebytes.org/
    Does Malwarebytes pick up any infections? If so, what does it call the infections?

  • Itunes cannot run because some of the required files are missing?

    This morning when I turned on my computer my itunes was suddenly not working. When I double click the desktop icon to open it up, I get an error message that reads:
    iTunes cannot run because some of the required files are missing. Please reinstall iTunes.
    I searched the FAQ archive and still cannot find an answer to my problem.
    THe last part of the error message says to reinstall itunes, but I cannot even get the corrupt version off. Is there anyway to save the music I have on here? Another user and I have separate iTUnes music, so a great deal of music will be lost, including things recently purchased.

    Thank you so very much. I don't know why I didn't think of that but it is up and running fine now
