Error message: "unable to load [...] from Sync Services

I've tried resetting sync history with no avail. On the "Info" tab of the device (iPhone 4), I am unable to check the "Sync Contacts with" and "Sync Calendars with" options. Until about a week ago, it always synchronised with Outlook 2010 without a problem. What can I do to fix this?

Unable to load from sync services

after upgrading to newest version of itunes, my iphone4 and ipad wont sync. I get the message about not being able to load from sync services. any suggestions?

Many thanks.
I don't usually associate the Windows Live LSPs with a LSP conflict, but I guess we'd better check.
Let's try wicless instructions from the following post. (This contains the netsh winsock reset instructions, which will return the Winsock key settings to their defaults, and clear away any LSP conflict or incidental damage in there.)

How do I fix error message "unable to load sync UI Corel localized.dll"

How do I fix an error message "Unable to load sync UI Corel localized.dll"? All of a sudden I can no longer sync my Windows PC to my iphone. I also noticed that just prior to the problem occuring there was an itunes software upgrade that occurred. It may or may not be related to the problem.

Hi Barrlee,
Thanks for using Apple Support Communities. If iTunes doesn't recognize your iPhone, this article may help:

If issues persist, a thorough removal and reinstall of iTunes would be the next thing to try:

Why do I get the error message "unable to load page (HTTP 502) when I try to open Mobile Web?

I have an LG Octane 3 basic phone.   Does everything I need, phone and text, and I never was interested in web or e-mail capabilities until I recently upgraded our plan to the "More Everything" and was able to use data and check e-mail and access the internet.   Whenever I try to open Mobile Web, I get the error message "unable to load page (HTTP 502)".    As of March 31, 2015, all of us basic phone users lose the "Mobile Email" app on our phones, and will have to access web versions of our e-mail via the web. Which is currently unavailable and doesn't work.
Over a week ago, did a chat session with a tech support rep, and she indicated that either she or an engineer would contact me with how to fix the problem.   Have not heard anything from anybody, and the deadline is approaching quickly.   Have no need of all the excess features of a smart phone, nor do I wish to be forced to jettison a perfectly working phone for my needs and buy something I don't want to be able to do 2 simple things.............check e-mail to see if there's something that needs to be answered right away, and to check traffic reports when I'm on the road, or find something in an area with which I'm not familiar.     Not really too much to ask, you would think....   )
Has anyone else had this same problem, and if so, how do we fix it....??? My next move is a phone call, but those haven't always been very productive.
If any of you have any ideas why this error keeps coming up and the web can't load, and some on how to fix it, I would really appreciate some advice.
Thanks in advance.
Karen

Since the chat session got no reply, I contacted Verizon by phone and a very nice level 2 tech created a trouble ticket and sent it up the food chain. Got a call back, maybe 2 days later, and had a nice, although very long session with a higher level tech. They had determined that the browser for the LG Octane is an old one and no longer supported by Verizon.    We tried everything we could to download the Opera browser, but since I was totally unable to get Mobile Web to work, couldn't do it.   The only other possible "fix" was to totally reset the phone to factory specs and try it again.   That would mean a lot of work on my part to move anything I didn't want to disappear off the phone, and find a place to forward texts that had to be saved.   Caught our tenants lying about why the rent was late (again), and need that for when I put them back on a lease....
Long story short is that unless we try this total reset, which isn't a sure fix, either, anyone who isn't able to access the Mobile Web with the LG Octane will have to change their plan to avoid paying for data that you can't access using any method.
I ran a test with an app that I knew was no longer valid.....that was sending photos to PixPlace.   Got the exact same error message as when trying to access Mobile Web to get the web version of my e-mail.   That just verified that the 502 error is, at least in the LG Octane, for an app that no longer works.   After today, we'll get the same thing when we try to access Mobile E-Mail.
Have to admit, it's a real ****-off, but this shouldn't surprise me, since Verizon won't repair older copper phone lines if you are in an area where FIOS is offered.
I am going to immediately change my husband's and my cell phone plan to one without data, and see what I can find that will still give unlimited calls and text. The way my luck runs, they won't offer one for a decent price. The other half has some very long-winded friends and he was always running over minutes, and some months are very text-heavy and I'd go over my limit.   Absolutely HATE touch screens, and am not looking forward to having to get a new phone.

Error message: "Unable to load screen : root. ChangeLocation.ChangeLocationStart"

I paid for & downloaded zagat to go app from handmark & it fails to run on my bb tour. Here is the error message I keep getting on my bb tour - "Unable to load screen : root.

Many years ago synced iCal with Microsoft program. Since installing Lion whenever I try to create an event in iCal it flashes up message "Unable to open Microsoft sync services Power PC applications no longer supported." How do I get rid of message?

Many years ago synced iCal with Microsoft program. Since installing Lion whenever I try to create an event in iCal it flashes up message "Unable to open Microsoft sync services Power PC applications no longer supported." How do I get rid of message?

Lion no longer supports PowerPC apps. If this is Microsoft Office 2008 (Entourage 2008) then you should disable the syncing services. (I don't have Office 2008 installed anymore so I don't know exactly what it's called anymore.) If you have Microsoft Office 2004 or earlier, then it can't be run on Lion at all since Lion removed Rosetta, which is what allowed a PPC app to run on an Intel based Mac.
Also, I believe Microsoft removed sync services from the current Outlook 2011 (which replaces Entourage) so even upgrading to a newer version of Microsoft Office will not get you back that calendar sync feature. Supposedly Microsoft is working on a new syncing system, but I wouldn't hold my breath.

Error message "Unable to load plug-in type"

Hi I used plugin registration tool and updated an existing plugin by a new dll.. and then afer that I started recieveing error messages on the CRM on our Dev environment. Error message "Unable to load plug-in type" it was registered for contact entity for
post create and update but we are getting this error on any entity updates and creates..
Any help on how to resolve this issue with be deeply appreciated.
thanks in advance,
Future MVP

While this thread is 3 years old, yet I just encountered the same problem about half an hour ago, and I believe this is a bug within CRM Solution Import routine.
What I had was a plugin which was imported previously. Then, I added new plugin steps and got 'Unable to load plugin type' when registering the new plugin steps I added.
The solution I have is:
a. Import just the plugin assembly without the new plugin steps, and publish.
b. The plugin assembly is now updated with the new plugin class definition. Then add the new plugin steps and import the solution again.
c. The solution should now be imported successfully.
What I believe the bug is CRM Solution Import routine checks for the plugin class/type definition in the existing plugin assembly in the server rather than the new plugin assembly in the solution being imported.
By the way, all solutions are unmanaged. Perhaps, the same bug will not happen in Managed solution.
HTH anyone else experiencing the same issue.

Hi Terry, A post is the message that anyone has just typed in. When you replied to me, that was your post. I am replying to you so this is my post. Think of it as sending an email or mailing a letter at the "post" office.
Now right at the top of the last post (message) you sent me is a Post#, then the date and time and under that the thread subject "Re: I am trying to download Adobe Flash Player 10 and I keep getting......
The first time that you posted, you described your problem. The next post after that is #1 and so on.
The Adobe Flash Player forum works very much like email except there are a lot of "threads". A thread is what each message you see is called. Everyone that registers can start their own thread (subject). Then other people see it and can post to your thread and try to help you with your problem.
You did pretty good, you registered, and you started your first thread
Now do you feel somewhat more relaxed? Hope so.
Take a look now and see if you can find the Post# and etc that I described above.
Thanks,

HP 7520 Photosmart scanning error message: Unable to connect to Web Services

After many successful efforts in the past, suddenly I cannot scan to email on my HP Photosmart 7520. I have tried several of the solutions posted to no avail. I keep getting the error message "Unable to connect to Web Services. Confirm Iternet access and try again." I'm on Mac OS X. Very frustrating; I would appreciate help.

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 for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert

I'm getting an error message, " unable to load data class information from sync services..." What do I do?

I'm getting an error message when I try to sync my iphone to my computer, "...unable to load data class information from sync services..." How do I fix this? I'm worried because my last computer was giving me this same error right before it crashed.

Error Message - Unable to Load Needed Components

0Error Message - Unable to Load Needed Components] Creative Sound Blaster 24-Li've came installed on my Dell PC and I have had no problems for 2 years.
Now when I click on Speaker Settings, Surround Mixer, Graphic Equaliser etc... I get the message "Unable to Load needed components - please reinstall the application".
So obviously, I used the Creative CD that came with my Dell PC and reinstalled the application.
And guess what, nothing changed, and I suppose this should not surprise me by now, having been in this industry for 20 years.
So I went searching for the components that could not be loaded, and guess again - yes they are all on my PC but will not load.
They are files like Speaker Manager (SpkMgr.spc) and Mixer Manager (MxMgr.mxc) and so on.
So I attempt to load them directly, and - you guessed it - another message saying "Invalid Public Key Security Object File - This file is invalid for use as the following: PKCS #7". (which means nothing to anyone). What a load of old rubbish.
I was under the impression that I purchased this software with my Dell PC, I certainly got the disk with it and now I cannot reinstall because of some certificate revocation error that I am sure almost no-one in the world knows what this means or can help. So this is what the industry has come to.
There is no point in reinstalling from the disk - the same problem reoccurs.
There is no point uninstalling all creative software, and then reinstalling - the same problem occurs.
Dell do not want to know, because the support people I spoke to were living in Katmandu or Tibet or Mumbai or somewhere cheap and remote, and probably being paid 2 dollars a day juggling their support work for Dell with milking the Yaks and fighting off the Maoist rebels.
Is there a miracle out there, or at least someone with a clue.
Cheers
Mark
