Failed iTunes update - now I can't open iTunes at all

iTunes update on Windows 7 failed - laptop was accidentally shut down. Now I can't open iTunes - I get these messages:
Runtime Error!
Program:C:\Program Files\iTunes\iTunes.exe
R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
and when I OK that there is a following message:
iTunes was not installed correctly. Please reinstall iTunes.
Error 7 (Windows error 1114)
Unfortunately, for some reason my laptop will not allow me to uninstall iTunes (erroneously says I don't have administrative authority).
I've tried restoring the system to a date prior to the iTunes update but that hasn't worked either.
I'm not particularly computer savvy so is there anyone out there who can offer some advice please?

Hi there,
Earlier iTunes (and supporting applications) need to be completely uninstalled before you can install the new version. Here's the complete Apple info on this: http://support.apple.com/kb/HT1923
Mobile device application will most likely fail to uninstall, so you would need to visit its location(s) and manually delete the files THEN folder(s). The location of the folders is documented in this link from Apple.

ITunes lost from failed iTunes update

Attempted an Apple iTunes update yesterday as prompted. It failed and left error messages: Microsoft Visual C+ + Runtime Library Runtime Error! Program: C:\Program Files (x86)\iTunes\iTunes.exe R6034 An application has made an attempt to load the C runtime library incorrectly. Please contact the application's support team for more information. OK
Then another box appears over that and says iTunes was not installed properly. Please reinstall iTunes Error 7 (Windows error 1114)
***Please forgive my ignorance, but if I uninstall iTunes and then reinstall iTunes, what happens to my library of music, podcasts, etc. ???? Will they just get shuffled into the reinstalled version? *****
Also, who and where are the "application's support team" mentioned in the first error box?
I use Windows Vista
(I use the "cloud" and I have Carbonite backup)

Thank you so very much. I read the full recent post on this subject by turingtest2 and clicked on and printed out the apple support page highlighted "Removing and reinstalling iTunes for .... Windows Vista" and carefully followed the complete instructions. After a few nail-bitting minutes, it all worked and the new iTunes was installed and all my stuff is BACK!!!!
How great to have each of your responses and help. Thanks again.

After a failed itunes update I attempted to open itunes and received a message "unable to locate component MSVCR80.clll, as well as an error message "Error 7 (Windows error 126). I was told to reinstall itunes, which I did, then received the same message

I have an itunes account on a pc running Windows Vista. After a failed update I can no longer open my itunes account. I receive 2 messages. The first says "unable to locate component MSVCR80.clll". Ther other is an error message which says "Error 7 (Windows error 126). It was suggested that reinstalling itunes might solve the problem. After doing so I receive the same messages. What now?

Stuck on grey screen with apple logo after failed iTunes update

I tried to install an update for iTunes 9.2 on my MacBook. During installation a box appeared telling me the update had failed. I clicked the 'Restart' button. Now it won't go past the grey screen with the apple logo and the rotating wheel; it just loads indefinitely. I have a very important document saved on the Mac which I've added to without backing it up. I'm worried that I will lose (or have already lost) a great deal of writing. Is there a way to get my computer running again without damaging my files? Because this computer was a gift, I don't have the software installation CDs that came with it (or Disk Utility). I'm also not very familiar with computers in general, so if you explain your solutions in a really basic way, I'd appreciate it. Any kind of advice would be extremely welcomed...

Resolve startup issues and perform disk maintenance with Disk Utility and fsck
* Last Modified: June 25, 2009
* Article: TS1417
* Old Article: 106214
[Email this article]
[Print this page]
Symptoms
If your computer won't start up normally, you may need to use a disk repair utility to fix the issue. Mac OS X includes two utilities for this—Disk Utility and fsck (a command-line utility). You can also use these even when your computer starts just fine but you want to check the disk for possible file system issues. For Mac OS X 10.4.3 or later, check out "About live verification in Mac OS X 10.4.3 or later," below.
Important: If you're using Mac OS X 10.4 or later, you should use Disk Utility instead of fsck, whenever possible.
In some situations, file system errors may prevent your computer from starting up. This can occur after an improper shutdown, forced restart, or power interruption. If your computer shows any of the following symptoms on startup, use a disk repair utility:
* Your computer partially starts but then displays a command line in a text-only environment. You may see the message, "file system dirty, run fsck." Below it, you'll see what's called a command-line prompt, indicated by a number sign (#), that allows you to type a command. If you see this, you'll need to run fsck from the command line (see "Use fsck if necessary," below).
* Your computer starts but either it won't reach the login screen, or it may reach the login screen but not load the Desktop after you log in. However, you can start up in single-user mode.
If your computer exhibits either of the above issues, here are some things to try to get your computer back to starting up properly again. If you can't find the system discs that came with your computer, see "Use fsck," below.
Products Affected
Mac OS X 10.4, Mac OS X 10.3, Mac OS X 10.2, Mac OS X 10.1
Resolution
Try a Safe Boot
If you're using Mac OS X 10.2 or later, you can start up your computer in Safe Mode, which includes an automatic disk check and repair. If you're using Mac OS X 10.1.5 or earlier, skip to the next section. A Safe Boot, which starts up your computer into Safe Mode, may allow you to start up your computer successfully using a reduced version of the system software. To do this, follow these steps:
1. Start up in Safe Mode.
2. After the system has fully started up, restart your computer again normally.
If the computer successfully restarts, you do not need to do any more troubleshooting. If the issue persists, try Disk Utility.
Try Disk Utility
1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Tip: Always start up your computer from an Install or Restore disc when using Disk Utility to verify or repair your startup volume. Otherwise, you might see some disk error messages.
Use fsck if necessary
fsck is a command-line utility that may be able to verify and repair a disk. If you can successfully start up in Safe Mode or use Disk Utility while started up from a disc, you don't need to use fsck. Here are some situations in which fsck may be necessary.
* Your Mac OS X disc isn't available.
* Your optical drive isn't available.
* You can't start with a Safe Boot by holding the Shift key during start up.
Tip: If you use a Mac OS X Extended (Journaled) formatted volume, such as with Mac OS X 10.3 or later, you probably won't need to use fsck. If you do use it for any reason, please be aware that benign error messages can appear.
If you're not sure how your volume is formatted and you can't start up from your Mac OS X volume to find out, type the following command in a command-line interface and then press Return: diskutil info /
If you see "File System: Journaled HFS+" returned, you have a Journaled volume.
To use fsck, you must run it from the command line. Unlike using your mouse pointer to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line.
Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt type:
/sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
Your computer should start up normally and allow you to log in.
Additional Information
About live verification in Mac OS X 10.4.3 or later
In Mac OS X 10.4.3 or later, you can verify your Mac OS X volume while started from it. This is known as live verification, and can be used in three different ways.
Option 1: Verify your disk using Disk Utility while started from the startup disk. To find out how to do this, see this article. Please note that live verification does not involve any disk repair, so if verification finds something that should be repaired, start up from your Mac OS X Install disc and use Disk Utility as described above in "Try Disk Utility."
Option 2 (advanced): Use the command line and the command-line utility, diskutil.
1. Start up your computer and log in as an administrator.
2. Open Terminal (/Applications/Utilities).
3. At the prompt, type the following command and then press Return:
diskutil verify /
Note: Don't use this method to check non-startup volumes.
You should see messages such as the following during the disk check:
Could not unmount disk for verification, attempting live verify
Started verify/repair on volume disk0s3 Macintosh HD
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD appears to be OK.
Mounting Disk
Verify/repair finished on volume disk0s3 Macintosh HD
Option 3 (advanced): Use the command line and the fsck_hfs -l command.
1. Start up your computer and log in as an administrator.
2. Open Terminal (/Applications/Utilities).
3. At the prompt, type the following command and then press Return to determine your filesytem ID:
df -hl
4. Look for some lines of text that look like this:
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s3 37G 20G 17G 55% /
/dev/disk0s5 37G 37G 641M 98% /Volumes/Storage
5. Make a note of the first "disk" name that appears after /dev/, such as "disk0s3." This is your filesystem ID for your startup volume.
6. At the prompt, type the following command and then press Return:
df -hl
7. Then type the following command, where "disk0s3" is your filesystem ID you noted in step 4, then press Return:
sudo fsck_hfs -l /dev/disk0s3
8. When prompted, enter your admin password, then press Return to begin the verification.
9. You should see messages like these during the disk check:
** /dev/rdisk0s3 (NO WRITE)
** Root file system
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
** Checking multi-linked files.
** Checking Catalog hierarchy.
** Checking Extended Attributes file.
** Checking volume bitmap.
** Checking volume information.
** The volume Macintosh HD appears to be OK.
Advanced information
If you're interested in UNIX-style command-line syntax, here's a look at how a couple of flags used above can influence fsck:
* The -y flag: Tells fsck that you want to answer "yes" to all questions about fixing, repairing, or salvaging information. This is the optimal approach, as answering "no" to any question causes fsck to stop. You cannot determine that all necessary repairs have been made until fsck completes and gives its final report.
* The -f flag: Forces fsck to check "clean" filesystems when preening.

* Handling "overlapped extent allocation" errors reported by Disk Utility or fsck
* Disk Utility reports "Underlying task reported failure" when repairing a volume

HT203167 yet again failed iTunes update has removed my purchased music

latest update has removed some of my purchased tunes update stalle part way!

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

Itunes update failed on 2 computers, couldn't find msvcr80.dll files.Now have no itunes at all

iTunes update failed on both computers. Couldn't find msvcr80.dll, now I have no iTunes at all. Is it iTunes or the computers?

I did NOT move the other folders (Album Artwork, Mobile Applications, Playlists, Previous iTunes Libraries) or files (iTunes Library, iTunes Library Extras, iTunes Library Genius, iTunes Music Library) that are located inside the Music/iTunes folders.
should be no problem. i'm doing this also.
Everything was working fine on both computers - Consolidated the library on the external drive and did the Change the location of the iTunes Media folder in Preferences on both computers, no problem.
However I added two movies and a few songs to my desktop Mac yesterday - all showed up and played fine after adding them - but when I plug the external drive into my laptop, the new additions don't appear in the library.
if you're purchasing content from the iTMS, you could use _*Home Sharing*_ to automatically add new content to all machines on your local network.
Am I right in guessing that it is because the iTunes Library file on the laptop isn't the same as the one on the desktop computer?
yes.
Is there a way to add them to the library listing on the laptop? If yes, is that something I need to do every time I connect the external drive to the laptop if I've added things from the desktop computer (I never add stuff on the laptop).
basically, yes. however, there's _*Home Sharing*_ and ... see below.
Should I have put the entire iTunes folder - files, folder and media - onto the external drive?
that's one possibility, however, only one Mac @ a time could access that library. there are other options:

Why can I no longer install iTunes updates on my computer? I keep getting messages saying it fails, and to do it manually, but then I get popups questioning whether I have the authority to make these changes. And it never updates.

ITunes update failed to reinstall on 64-bit Windows 7 Home Premium

Never had problems before with iTunes update. I never had to do anything besides accepting the agreement, followed the prompts, and clicked "Finish" at the end of the installation. But the update that came 3 days ago failed to install, with a message to get the 64-bit version of iTunes even though iTunes have always installed to the same 64-bit OS computer. After countless hours of uninstalling and reinstalling, and registry clean up, I'm now coming up at 2 consecutive reinstallations with this error message:
Could not open key:

I have read other postings with identical error message but no answers either here or on the Apple's forum site. I will appreciate any help, workaround or whatever.
Thanks.

I also face the same problem installing it on my Window 7 Professional. Have you found an answer to this? Thanks.

I ran an iTunes update on a PC Win 7 and got "apple mobile device failed to start verify that you have sufficient privileges to start system services" ? I deleted iTunes, ran download, and now I can't reinstall. I am logged onto the PC as Administrator.

Troubleshooting issues with iTunes for Windows updates

ITunes update always fails on Windows 7 x64

I have had this problem for over a year on my Windows 7 64-bit system. Whenever there is a new version of iTunes, I try and update using the iTunes Software Update notification that pops up. This always fails to install. I am then forced to uninstall it fully and re-install using the directions located here:
http://support.apple.com/kb/ht1923
The above works but is a major hassle. I don't understand why this keeps happening and have looked for solutions here and elsewhere. Any help would be appreciated.
Thanks!

I have had this problem on my x64 Win7 machine for as long as I can remember. I may however have found a solution. I recently added another User Account (non-admin) to my machine so my wife could use it too. Whilst logged in her account today iTunes popped up with an update. I had tried this update (10.6.3.25) on my windows account a couple of times with it failing each time. I had decided I could no longer be bothered going through the full uninstall/reinstall process again and wasn't going to bother.
For some reason though I thought I'd give it a go on my wife's windows login. It worked just fine.......
So my suggestion is to create another Windows User Account and see if you can update iTunes from that account instead. It's the first time in at least 18 months that iTunes update has worked properly.

I ran an iTunes update. It failed with the message System Error. The program can't start because MSVCR80.DLL is missing from your computer. Try reinstalling the program to fix this problem. I tried reinstalling but get the same message.

I ran an iTunes update. It failed with the message "System Error. The program can't start because MSVCR80.DLL is missing from your computer. Try reinstalling the program to fix this problem." I tried reinstalling but get the same message. I looked in my Recycle Bin for that file name but there is none there. Is this a new file that iTunes wants?

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.
