Fix: iTunes was unable to load provider data from Sync Services. Reconnect or try again later

Are you getting the error iTunes was unable to load provider data from Sync Services. Reconnect or try again later? We have had reports of users experiencing this issue with the latest iOS 5 beta and the iTunes 10.5 beta.  You may also be receiving this error on non beta software as well.

Since I have not personally seen this error this is no way for me to verify that these solutions fix the problem.  In iOS 5 if you just hit OK and ignore the problem you can still Sync.  Other people may have problems syncing on older versions of iOS.

This error seems to happen mostly in Windows 7 systems.In order to fix the problem you can try renaming the sqllite file in Windows/System32 or Windows/SysWOW64 to sqllite.dll.old.  This will allow a new file to be written and the old file will get ignored.

 

Another possible fix would be (Win7 64 bit with Roaming profile):

1. Unplug iPhone

2. Rename theSyncServices folder found at C:\Users\<username>\AppData\Roaming\AppleComputer to SyncServices_Old

3. Reconnect iPhone

 

If you know of any other solutions please post them in the comments.  You may also want to read Apple’s long support thread.

      Thank you Siddhant. My blessings on you. After trying all the other fixes, yours is the one that worked for me.
      As a note to others:
      I’m running Vista.
      Since the iTunes is on another user account, I had to give that user Admin privileges first. Ran itunes as administrator by right clicking and selecting that option.

      where can you find the syncService File?

  4. inside the SyncServices folder is a ‘local’ folder. Delete that folder (after shutting down all sync/itunes services running) and plug any iphone,ipad again. A local folder will be automatically recreated and the error is gone permanently.

      As instructed, I deleted the “local” folder in Windows 7 Sync Services. It’s important to use the Task Manager to abort all sync/iTunes programs. Then I got another iTunes error message: “iTunes was unable to load data class information from Sync Services.” Un and re-installing iTunes fixed that. Everything is sync’ing with Outlook now.

        Bill Payne’s suggestion worked like a charm for me AFTER I first closed/stopped (in Task Manager, under “Processes”) the “syncserver.exe” file. Thanks Bill P!

  8. Here is what worked for me (iTunes 10.5 on Win7SP1_x64):
    1. Unplug iPhone and close iTunes
    2. Kill the process SyncServer.exe and any process starting with “Apple” using Task Manager
    2. Rename theSyncServices folder found at C:\Users\\AppData\Roaming\AppleComputer to SyncServices_Old
    3. Reconnect iPhone and open iTunes

    BTW It looks like you can sync just fine if you just ignore the error message but you can’t. The problem you will have is iTunes won’t be able to sync with your Outlook or any other mail application on your computer. In my case I couldn’t get notes to sync with Outlook untill I fixed this.

Right click this folder and rename it SyncServices_Old. Close this window. Attach your iphone/device and open iTunes. …we all started somewhere :-)

    In order to change the name of Sync Services to Sync Services_Old, most people, including me, will need to bring up Windows in Safe Mode to allow the change to occur. This is due to the folder being Read Only.

  16. Problem I am having with renaming the folder is it won’t let me because it says it is running, even if I have iTunes down. I also delte all “Apple” items in the task manager, which then closes my explorer where I am trying to change the name, then when I go back to the folder again, it says it’s running again. Stuck in a loop.

  17. Hi Alan,

    It’s easy bro. What you need to do is to go to the task manager: Ctrl+Shift+Esc.

    Then go to “Processes”, you’ll find 2 processes from iTunes. Right Click on them and End the process.

    Than you’ll be able to rename the folder.

    I should’ve been bright enough to go to “processes”, but I’m not completely PC literate, so I forget this stuff when I don’t use the task manager but very seldom.

    I appreciate the help! I can’t try it until I get home later, but I’ll let you know. Thanks again!

    • Is SyncServices.exe one that should be stopped? I stopped other processes, but wasn’t sure about this one. And so far, no dice…

      Thumb up 0 Thumb down 0

      • Well, I ended SyncServices.exe then was able to rename the folder. I didn’t get the error message when i first went to sync, but it also said I needed to restore my phone to factory settings because it didn’t recognize it. I closed the error message without hitting ok and unplugged the phone. then i restarted itunes and plugged my phone back in and it was fine. It said it was starting to sync, but it locked up. I had to unplug the phone again, end task on iTunes and start it back up. Then plugeed phone back in. Got error message regarding sync services again. so i just clicked OK and ran the sync, which worked fine. But obviously renaming the folder was not a permanent fix.

    • Hello. I got the same problem that everybody else and it´s started after update to iTunes 10. and iPhone to iOS5.

      But i don´t find that kind of file “SyncServices” from my comp, can somebody help???

      I know that the file was there when i try to solve this problem 2 weeks ago, but now, after installing iTunes x 10, it´s gone.. Where can i find it?

      Updated Win7, latest version of iTunes and iPhone.

        Thumb up 0 Thumb down 0

        • Yeah, i got that option chosed, but it won´t show it.

          I actually find find SyncServer from c: / Program Files / Common files /apple / mobile device support and there is some synserver and syncservices files also (dll).. When you doubleclick SS, it´s open´s a black banner, like same as you start writing a code, but you cannot do anything.

          Maybe i just try to move some files to that roaming section but what files??

          Messy, ha:)??

    i just had this message for the fist time “iTunes was unable to load provider data from Sync Services. Reconnect or try again later”
    what i did is that:
    - i unplugged my iphone 4
    - clicked on “edit” in itunes, “Preferences”, “devices”, “reset synck history”
    - Uninstalled itunes
    - restarted the lap top
    - reinstalled itunes
    then i tired and the iphone synced fine. i tried it a few times and it was fine.
    but i have 2 questions:
    1- could this be cause by excessive syncing, since i do sync my phone almost twice a week.
    2- is what i did good enough for a solution or do i need to rename folders and resort to the other solutions provided?
