After an update, iTunes no longer works

I'm sorry for such a long story. Several weeks ago, iTunes informed me of an available update. I clicked to update. The next time I open iTunes, the iTunes store no longer worked. Everything else worked fine. I solved this problem by uninstalling and reinstalling. The next time an update was available, this entirely same process happened. After finally getting everything working smoothly for several days yet another update was available. This update being 10.4.1. Fearing the same problem and not having time to deal with it, I declined the update. The next time I opened iTunes, my library no longer existed. The files are on my hard drive still so I attempted to reload them to iTunes. iTunes acts like it is loading the files but in reality is not loading them. Once it is finished, they are still not in my iTunes library. I have uninstalled and reinstalled 10 different times. I am always careful to uninstall all apple related files ie. QuickTime, Bonjour, etc... I have even gone so far as to restore my computer to a previous date. How can I fix this problem?

Don't know. Not my area of expertise. I was just trying to help in some way. You can check this:

After the last update iTunes no longer works... "This application failed to start because MSVCF80.dll was not found. Re-installing the application may fix this problem" I tried and it did not fix the problem?

HT204368 after downloading ios7, iTunes no longer works through my blue tooth (car)- but other programs (pandora) work just fine

After downloading ios 7.02, iTunes no longer works through my blue tooth (car), but other music apps work fine. iTunes and iTunes radio work fine though headset and on speaker, but won't work through bluetooth.
Anything that can be changed in 'settings' or with my iTunes so I can use it through my blue tooth?

Hi, milljam7.
Thank you for visiting Apple Support Communities.
Sometimes closing all applications open in multitasking and power cycling the device can resolve the issue.

Sync; Windows Updater; iTunes no longer works

I connected my iPhone 4 to the USB port, synced it and then left the phone connected and iTunes running when I went to bed. When I woke up, the welcome screen was on and, after login, I received the message that Windows updater had performed some updates. When I clicked on iTunes, I received an error message that iTunes had some missing files and needed to be reinstalled. I attempted to do a system restore to recapture my iTunes library before the update. System restore would not work either. I am concerned that my iTunes library will be lost if I reinstall iTunes as suggested by the error message. HELP!

Refer to the first box on on this page: Troubleshooting issues with iTunes for Windows updates That should resolve this issue.

After Latest Update, Acrobat no longer works

Yesterday the Adobe updater came up saying that there were some updates to install. After installing the updates, Acrobat now comes up with a Fatal Error. It said something to the effect Acrobat failed to load its core dll file and I also got an error saying:
acrodist.exe - Application Error
The application failed to initialize properly (0xc000022). Click OK to terminate the application.
Here is my setup:
Design Premium CS4 with Acrobat 9 Pro
Windows Vista Ultimate
I tried running a repair re-install and that didn't work. Still get the same error. If someone can help with this it would be greatly appreciated!
Thanks

I was giong to say, "Help me, Adobe Joe Kenobi", but it looks like you're growing a beard waiting for an answer, too.
The same thing happened to me today. I trusted the "update" message since it was from Adobe, and apprently did so at my own peril. Now I get the "failed to load Core dll" message with a secondary reference to a memory address.
Just an observation, but what good are these forums when there are no answers? I see this problem as "Caused by Adobe Update", and would expect them to troublshoot and offer up a remedy. Since you've been waiting over two months with no response, I suppose it's time to trek off wasting more of my precious time to fix their problem. If I find the solution, I'll post it back to you.
May the Force be with you.

After firmware update wifi no longer works on ipad mini

wifi worked fine before upgrade to ios6.02
it sees networks but cannot join them? 4G works fine

Or maybe a reboot of the router would help? Even though everytihng else is working, it might solve the problem. Unplug it for about 30 seconds and then plug it in again.
A reboot of the iPad might be a good idea as well.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Since last update on Mavericks, the picture attachement to a movie in iTunes no longer works. Any idea ?

Since last update on Mavericks, the picture attachement to a movie in iTunes no longer works. Any idea ?
Picture added is not displayed in the finder ; when transfering the movie to an Ipad, it is not displayed either.

Working here just fine. Try reinstalling:
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

After doing a widows update itunes will not work at all

after doing a widows update itunes will not work at all

hiya!
I get the itunes has encounterd a problem and needs to close, sorry for the inconvenience error, no specific error number. I do not have QT installed,
not having QT installed is what will be causing your itunes error message at the moment. let's try a careful standalone QT 7.1 install.
download and save a copy of the QT 7.1 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 Standalone Installer
if that install goes through okay, does your itunes launch properly again?
(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.)
love, b

My iPod nano 5th generation is not recognized by iTunes. I did update, but still, it won't work. I don't want to uninstall the iTunes cos I don't want to lose my music and audio books. What to do? It started after I updated iTunes.

iPod appears in Windows but not in iTunes

ITunes no longer works on my Windows VISTA system. Get error msg saying C runtime library incorrectly... Error 7, Windows error 1114..

iTunes no longer works on my Windows VISTA system. Get error msg saying an application is attempting to access C runtime library incorrectly... Error 7, Windows error 1114. Same msg, or one that says unable to install, when trying to update or reinstall iTunes. iTunes worked well up until about a month ago when this error msg starting appearing.

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

10.5.7: Automatic Software Update Feature No Longer Works

Ever since I installed 10.5.7 the automatic Software Update feature no longer works. (Manual updates work fine.) For example, here's what happened today with Safari 4.0.2:
1. After powering up I got the Software Update icon on the Dock.
2. I clicked it and it said I had updates that would require a reboot and it asked the usual stuff. (It didn't say what would update.)
3. I clicked to reboot now and it asked for my password and rebooted.
4. My MacBook rebooted but nothing had been updated.
So, I went to the Apple menu to check for updates and it said I had Safari 4.0.2 ready to be installed. This time, it worked. Unfortunately, I have to do this two-step process on every update that requires a reboot. I could turn off the automatic updates and just do everything manually but I prefer the automatic way. (I had it before, too.)
Thanks in adavance,
Brian

Jeffery,
Thank you for your quick response!

How often do you have SU to check for updates? And do you have "Download important updates automatically" checked as well?{quote}
I have check for updates weekly and download important updates automatically enabled.
{quote}I'm thinking that the first time you approved the update, that it could have been for something that was already downloaded in the background, and just waiting for you to OK the install.
Then when you rebooted, and did the manual check, it found that the Safari update was available as well.{quote}
Interesting. I hadn't thought about that. ☺
{quote}There could be a host of other issues... but check the "installed updates" in the SU preferences, and see what, if anything, was installed right before the last Safari update... note the date and times and see if my theory might be correct.{quote}
Here's what it shows for the last month:

Also, I don't think it matters but I did upgrade VLC to 1.0 the previous day.

After the update iTunes keeps crashing and won't play any of my music and keeps restarting my phone.

Anyone else have this problem and resolved it?
Thank you!

Well, I hadn't rebooted after the 7.1.1 upgrade, but obviously I had to restart iTunes. After I rebooted my iBook iTunes worked... Maybe the 7.1.1 update should be marked with a must reboot?

I have an ipod nano 7th generation and can not get it recognised by my Windows 8.1 laptop (it appears briefly on My computer, then disappears). This happened after I updated iTunes to the latest version. Does that have something to do with it?
