    When I connect my iTouch to my PC (windows 7) an error message is displayed reading "iTunes was unable to load dataclass information from sync services. Reconnect or try again later". I have completely uninstalled and then reinstalled iTunes. I have also completely reset my iTouch to factory defaults. I have even followed all the advice provided previously to other forum member with the same problem. Nothing seems to work. Please help me someone.

    I'm getting the same problem with both my IPad 4 and iPhone 5
    Just started a few weeks back, Since then I have had two Itunes updates.
    Is this something Apple is aware of and trying to fix?

  • ... unable to load dataclass information from Sync Services = Iphone Sync

    " Itunes was unable to load dataclass information from Sync Services. Reconnect or try again later. " - this is the message I receive after Iphone is plugged in. Itunes is 7.7 and Iphone is 2.0 at this point, only started happening after the updates of both.
    On a separate note, this same Itunes does not recognize Outlook as an option to sync from and all attempts to press Configure button yield zero result. I have a hunch that tells me the two are related ) . If any of you have had that problem, please post. The search turned up zero related posts.
    Cheers.

    I'm getting the same thing. I came into the office all excited to get the 2.0 update, ran the update and now my phone is stuck on the "slide for emergency" USB/Globe screen.
    When I try and load itunes and connect to the phone I get the same "itunes was unable to load dataclass information from Sync Services. Reconnect or try again later."
    I've reconnected and waited and still no luck.
    here's the sequence, when opening itunes with the phone connected:
    Open iTunes, it waits for a while trying to connect to the iTunes store, then it comes back and says "We could not complete your iTunes Store request. The network connection has timed out."
    I know my network connection is fine. The iTunes diagnostic even says so.
    I click Ok there and get the iPhone listed in the left index thing, but all I get in the body is a big "iPhone"
    Then it gives another "Accessing iTunes Store" status and the same "we could not complete..."
    help, please?

  • ITunes was unable to load dataclass information from Sync Services

    Hi,
    I have Iphone 3GS with the latest version 3.1.3 and iTunes 9.1. After i uograded my iPhone to the latest version i am not able to sync with the iTunes and receive the message "iTunes was unable to load dataclass information from Sync Services, Reconnect or Try later". I am using Windows XP with Symantec Endpoint protection.
    I have tried following steps to troubleshoot the problem but all my attempts have failed,
    1. Uninstall iTunes by Removing, iTunes, QuickTime, BonJour, iPhone congiguration Utility and Bonjour. Remove all the iTunes and related folder from the C:/ drive
    2. Restart the computer and intall the latest version of iTunes and Quicktime
    3. Restore the iPhone to the factory settings using iTunes
    4. Restart the system as well as hard Boot the iPhone (Hold Start and Wake/Sleep Button)before connecting again
    5. Repeat the Steps 1 and 2 after restoring the iPhone
    I am still getting the same error and now I can't even open the first page for iPhone in iTunes when I connect it to my computer. All my content is still in iTunes but everything is lost on the iPhone.
    I searched the Apple support and they talk about problem with the Symantec Endpoint. I have the latest version of Symantec endpoint way above what is mentioned on the Apple support page.
    Can someone please help me, it seems restore worked for most of the people facing this issue, but for me even restore is not working.
    With Regards,
    Ankur

    I got a present of an itouch. This is my first time back to apple after 5 years. I cant get my itouch to sync due to dataclass error on Windows XP pro. I have installed the latest version of itunes 9.2.1.
    WHAT IS THE POINT IN OWNING A DEVICE FOR PLAYING MUSIC WHEN YOU CANT LOAD THE MUSIC !!!!!
    Does anyone have a solution or alternatively (shock horror) Apple could actually get its AR*E in gear and fix the problem. I would also suggest that Apple would post a friggen solution on its website, but no that may be too much to ask.
    very frustrated. any help gratefully received otherwise the touch gets thrown out.
    thanks

  • ITunes was unable to load dataclass information from Sync Services-Solution

    Hello all. I recently upgraded to iTunes 9.1.1.12 on a laptop with Windows XP Pro and the latest iPhone OS (as of May 16,2010). Right after that, I started getting the "iTunes was unable to load dataclass information from Sync Services" error message. After I dismissed that window, it would go ahead and indicate that it was synching for a minute or two, and then indicate (in iTunes) that it was backing up the iPhone. This will run forever unless cancelled and the phone would not synch.
    After reading various solutions that worked for others (install Mobile Me, reinstall itunes, run diagnostics, all with numerous reboots in between), this is what worked for me:
    1) Open up Windows Services, and stop the Apple Mobile Device and iPod Service, and mark them as manual (as opposed to Automatic).
    2) Deinstall iTunes
    3) Delete the c:\program files\common files\apple folder (and all sub folders within). This is where the services are stored, and when I did all of these steps without doing this step, it didn't fix my problem. By deleting this folder, you insure that the iTunes install reinstalls these. You should see the services that were stopped in step 1, running again after the install is done. Note: I don't use Safari or QuickTime on my laptop, so I can't say whether or not this step would have any impact on those apps.
    4) Reinstall iTunes.
    5) Connect the iphone to your computer.
    6) At this point, I still got the dataclass error, so I immediately cancelled the synch.
    7) Run the diagnostics for the iphone (connectivity and synch).
    8) At this point, two DOS windows launched, and I did get another error about being able connect to the synch server.
    9) Closed the error message and disconnected the iphone (the phone at this point did not indicate that a synch was occurring).
    10) Reconnected the iphone and, voila, it's been working fine ever since.
    Hope this helps someone else out until Apple deals with the 9.1.1.12 (and .11) issues with synching.

    Either do Windows Control Panel → Administrative Tools and then picking "Services" or typing "Services.msc" in the Run command on Start menu.

  • "Unable to load dataclass information from Sync Services"  Any ideas?

    I upgraded to iTunes 7.7 last night and now I get an annoying constant stream of errors that read "AppleMobileDeviceHelper has stopped working". Multiple reinstalls have not stopped it.
    Against my better judgement, I upgraded my phone to 2.0. Found out that I lost everything on my phone. It is activated and will work but I cannot sync it with iTunes. All I get is a message stating, "iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later."
    iTunes won't recognize my phone. I can move songs and stuff to it by drop and drag but if I click the "iPhone" in iTunes, nothing happens. I put my phone in recovery mode. iTunes linked to it and reinstalled 2.0 but I still get the same problem.
    I'm real frustrated and Apple has not posted anything about this problem.
    Does anyone have any ideas on what is the going on? Is my phone nerfed?

    Try disabling your firewall, virus SW, and if it still won't sync, I would try disabling the communications services one by one until it clears. When I'm troubleshooting this sort of problem, I first look into the system reports (MY Computer, (right-click) manage, event viewer, Windows Logs, and look into each of the sub log sections for the error. This will often point you in the right direction. If this fails, I do a clean boot with all extraneous run-times and services disabled. usually the problem will be solved. I then start turning on the various run-time routines and services until I find the culprit.
    My attitude about this is that I won't waste my time chasing problems like this unless they are critical. Paying $$$ for a 3G iPhone and then having to troubleshoot the SW is not my cup of tea. I only pursued this because my wife and both kids got 3G's but I have them running both XP and Vista. One Vista machine synced OK, but mine would not. Intellectual curiosity led to find out why.

  • ITunes 9.1 was unable to load dataclass information from Sync Services.

    Everything was working perfectly fine on 9.0, then i upgraded to 9.1 version and my iPod Touch 3G stopped syncing properly (error as in subject). I tried many things, checked dll's, restarted services, everything without success. SO...
    I uninstalled every single apple program and couple non applce. Deleted every Apple related file, even all those hidden in users/common files/app data folders. Double checked everything and restarted PC. THEN I downloaded full version of iTunes 9.1 64bit and installed.
    Aaaand I restarted everything, lunched iTunes, plugged iPod in. Some Apple drivers installed themselves, then iTunes was frozen for couple minutes. Finally iPod shown in iTunes. I tried to sync and... BAM. Still broken, still same error "iTunes 9.1 was unable to load dataclass information from Sync Services. Reconnect or try again later"
    Please help, my iPod is useless. Can u release new, working iTunes?

    OK i have to say, i finally fixed it. Now its fully working without ANY problems, here is what i did (before trying this u should probably do this http://support.apple.com/kb/HT1923):
    1. Unplug every external Card Reader.
    2. Unplug every Card Reader in your PC (they are plugged into motherboard)
    3. Unplug every USB Hub.
    4. Unplug every USB Drive or USB HDD.
    5. Plug in Ipod Touch/iPhone.
    6. Go to Device Manager.
    7. Search for "USB Mass Storage Device" in Universal Serial Bus Controler.
    8. Right click on it and UNINSTALL.
    9. Search for "Scan for hardware changes", click on it and wait a bit.
    10. Turn on iTunes and check if its working.
    Now it should work like a charm.

  • ITunes was unable to load dataclass information from Sync Services. Reconne

    I'm getting the following error on iTunes 8 when quitting:
    "iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later."
    Anyone else seeing this?
    Don

    I started getting the annoying “iTunes was unable to load dataclass information from Sync Services. Reconnect or try again later.” error when i installed iPhone 3.0 beta onto my 1G iPhone. I have uninstalled iTunes (version 8.1), uninstalled Apple’s Mobile Device Support and reinstalled both of them but that did not fix the problem. I have also installed an older version of iTunes but that did not help as well. The error is not just annoying, i was not able to restore from my iPhone backups. I made a mistake in getting iPhone 3.0 beta onto my iPhone and instead of “update”, i chose “restore”. That wiped out all the App Store applications that i had installed. I could easily re-install the applications but there was no way for me to restore the saved data for some of the apps like eWallet and Gas Cubby. Until iPhone 3.0 beta is jailbroken, restoring a backup is the only way that i am aware of that can restore the app data.
    From the Console log, i noticed these errors were generated whenever an iPhone is connected to my Mac Pro:

  • Help! "iTunes was unable to load dataclass information from Sync Services."

    Help! what to do? When you connect iphone, the program writes this message "iTunes was unable to load dataclass information from Sync Services."

    It could be possible the service is disables. Go into control panel of your pc, into administrative services, then click in services. There you will see a list of services. Find the apple and itunes services. See if they say disabled. If they do, right click on it, then another dialogue pops up. It will stay stopped. Scroll in there and put automatic. Then hit apply. Then click on start. It will then apply the service and you should be able to connect your ipod.
    Have you registered this other ipod for iTunes on your pc?

  • Every time I sync my iPod or iPad I get an error message "unable to load provider data from Sync Services"

    Every time I connect my my iPod or iPad to my laptop  I get the error message "iTunes was unable to load provider data from Sync Services. Reconnect or try again later" There is no problem with my internet connection and syncing then seems to occur OK.  I upgraded to iOS 5 recently but have been getting the problem for several months. Due to recent problems with iCloud I am now concerned that this may be something significant that could lead to my losing data.
    Anyone got any ideas?

    Doublechecking. You've tried the following document?

  • "itunes was unable to load dataclass information from sync services"-crash

    I recently got the 2g iPod touch. Before i could sync it initially for a few times. But today, I plugged in my iPod and it won't sync. iTunes works perfectly when i don't plug it in. Also my old 30g iPod classic works fine when plugged in. I'm not sure if iTunes is missing some file for the Touch, or if it's the touch thats broken. The other day, somehow multiple .dll files became currupted, including those attached to Microsoft Office and flash. Is it possible that itunes is missing a .dll file for the sync? I have tried repairing itunes, and also uninstalling and reinstalling it. Is there anything to do to fix it?
