Multiple error messages in iTunes

I have an iPhone 3Gs. I updated iTunes, then I went to update my iPhone and sync it. But now I'm getting 4 error messages: AppleMobileDeviceHelper has encountered a problem and needs to close; YahooSync has encountered a problem and needs to close; WindowsMailSync has encountered a problem and needs to close; and iTunes was unable to load dataclass information from sync services. Reconnect or try again later. I have been getting these error messages for a few days now. iTunes doesn't recognize my phone anymore either, so now I cannot sync my phone at all. Apple support had me back up my phone and restore it to its original settings, but now my phone is the same as the day I bought it: no contacts, no apps, no music, no photos. I was wondering if this has happened to anyone else. I had read that people were having issues syncing with Vista, but I have Windows XP. I appreciate any information anyone has. Thank you, Happy Holidays!

iTunes was unable to load dataclass information from sync services
Just doublechecking. In the course of your troubleshooting to date, have you worked through the following document?

I want to Sync my iPhone 4 to iTunes however I get an error message from iTunes each time I connect the phone to the PC saying that I should restore to factory settings. Frustrating because it's already annoying enough that I can't drag and drop mp3's!!!

I have never been so frustrated before in my life with any phone. I find it obnoxious as it is that I cannot simply drag and drop files (especially MP3's) straight from my PC directly into my phone, which I have been used to doing up until now. Everyone who convinced me to get the iPhone has instructed me that my frustration can be fixed by downloading iTunes and syncing it all up via that program (which I have never used before). So, I downloaded the program successfully, however when I connect the iPhone 4 to the PC and iTunes is open, I get an error message that 'iTunes cannot read the content of the iPhone "iPhone" and that I should go to the Preferences tab of the iPhone and select 'restore' to restore this phone to factory settings. First of all, I don't understand why I need to do that. I have already downloaded apps and other important things in the 2 days that I have the phone. I am also scared that it will erase my contacts. This is such a headache. Music is very imporatant to me, but I am getting so frustrated that I don't have freedom over the phone which I thought was supposed to be one of the best out there. I would really appreciate help in this matter. I am sure the phone is great but I am on the verge of taking it back and getting something else.

Hey joshuafromisr,
If you resintall iTunes, it should fix the issue. The following document will go over how to remove iTunes fully and then reinstall. Depending on what version of Windows you're running you'll either follow the directions here:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

or here:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7

I am trying to open my iTunes on a Windows XP laptop and get the error message 42404 "iTunes application could not be opened. Please repair or reinstall QuickTime". I did that and it did not help. Any ideas?

Let's see if a more rigorous uninstall/reinstall procedure gets us past that, nancy. See the following troubleshooting document:

Itunes won't open on my Vista Ultimate OS-error message is "ITunes won't open w/o Apple applications support, uninstalled and installed numerous time, QuickTime too?

Itunes will not boot on Vista Ultimate- error message is Itunes cannot opperate w/o Apple Application Support
ITunes has been uninstalled and reinstalled numerous times, program files and Window files have been checked and deleted.
All I want to do is update my I4 IPhone

Quicktime doesn't open either and sends same error message

I can't open my Itunes keep receiving error message- The iTunes Library.itl file cannot be found or created. The default location for this file is in the "i Tunes" folder in the "Music" folder

I can't open my Itunes keep receiving error message- The iTunes Library.itl file cannot be found or created. The default location for this file is in the "i Tunes" folder in the "Music" folder. I have even tried removing and reinstalling iTunes and it still does work because I continue to receive this error message. Please Help!

Anyone can help to advice how to solve this issue ?

Can anyone help me? The iTunes update corrupted my program. I uninstalled, and then reinstalled iTunes; only to find an error message about iTunes Helper. After several fruitless, repeat attempts, I am at a loss. Please help-

Many thanks.
With the Error 2, let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR suitable for your PC (there's a 32-bit Windows version and a 64-bit Windows version):
http://www.rarlab.com/download.htm
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.)

How to raise multiple error messages at a time in a BADI

Hi all,
I'm using CHECK method of BADI ME_PROCESS_PO_CUST for some validation in ME21N/ME22N. I want to raise multiple error message at a time, when user clicks on Check button or Save button. Please let me know, is there any function module for this or is there any particular procedure for this?
Thanks in Advance,
Siva Sankar.

Hi,
Raising messages from within BAdis is not a good choice and from the look of it , it appears to be causing a dump.
Look if the BAdi interface has any exceptions defined for the method, if so, raise the exception with your message like:
MESSAGE e002(sy) WITH 'Error' RAISING <badi_exception>.
Otherwise call the FM POPUP_TO_CONFIRM To show msgs to user

I have been given a new ipod nano to replace my much loved but old ipod. When I plug it into my laptop to sync it I get an error message stating "itunes.exe - entry point not found. The procedure entry point AVCFAAssetCreateWithByteStreanAndOptions could not be located in the dynamic link library
AVFoundationCF.dll" I cannot acces my itunes or download a new versiona as this keeps flashing up. Any ideas? Please help, my life is meaningless without my music!!

When I attempt to sych with I tunes I get the following Error Message. "Itunes was unable to load data class information from synch services. Reconnect or try again later." How do I fix this? This started happening after I updated to the latest version

My iPods are working fine...this is just on our iPhone 3GSs....friend said his iPhone 4 was working fine with upgrade.
Tried: the winsock reset, uninstall/re-install of iTunes, shut the firewall down. Even called Apple...and after 2 hours of being told that "I'm savvy and have done everything they'd recommend" still with no fix...
Still: Takes over 2 minutes (not hooked up to phone) to open Edit-Preferences-Device...and can't find any backups?!?! Takes over 2 minutes to even open the phone to change spps, musice, books, etc....but won't let me do anything with contacts...wonder if this is what that error message is about (because I don't actually sync to an email program, I've just kept it all on the phone - mistake).

ITunes stopped working on Windows 8. Error message 7: iTunes was not installed correctly.

I have Windows 8. Originally iTunes worked fine, then it couldn't update (said it was unsuccessful). Then it stopped working, so I (after much research) tried a long and tiresome method of removing all Apple products and re-installing them. I did this 3 times and it eventually worked and has been working fine for a few months. Recently, when trying to update, it has said "update successful", but when checking for new updates, finds the same one it supposedly just installed, wanting to install it again. For a few weeks now it has not worked at all, saying "error message 7: iTunes was not installed correctly" when I attempt to open iTunes. I can't bring myself to go through the whole process again of uninstalling and reinstalling everything, it took hours and it clearly doesn't solve the problem. I have no idea what the problem is. Reinstalling only iTunes doesn't work. The support pages have no advice available for my crappy version of Windows.
Please help me!

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.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
It shouldn't really take that long to do, assuming it goes smoothly.
