ITunes application could not be oppened. An unknown error occurred (-200).

Hi--I'm having trouble since my latest upgrade or even before that. I've tried removing and reinstalling iTunes and iPod but still keep getting the error message (-200). Can someone help? I'm unable to even open iTunes anymore, let alone manipulate my music in my playlists. Any suggestions?
Thanks!!
Lela

the -200 is generally caused by a broken quicktime. (itunes requires a properly functioning QuickTime in order to work properly.)
let's try this technique first.
head into your Add/Remove programs. uninstall QuickTime.
Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the QuickTime folder and click Delete from the shortcut menu.
5. Navigate to C:\Windows\system32\.
6. Remove the files QuickTime.qts and QuicktimeVR.qtx.
7. Restart your computer.
next, we'll get a fresh copy of QuickTime into your PC by doing a repair install of itunes.
go into Add/Remove and select itunes. click "Change" and then click "Repair".
if the repair install goes through okay, restart the PC and try launching itunes again. does it launch properly now?

Itunes application could not be opened. an unknown error occurred (13010)

Using iTunes 8.
Get this error when i try to open iTunes...itunes application could not be opened. an unknown error occurred (13010)
It just shows that it tries to run in the Processes tab in the Task Manager. I get the error then the pocesses stops.
I've followed all the instructions in the attached link but with no luck:

I created a new user account and iTunes opens fine...
Can anyone help.??

I too am having the same problem. I have followed the above advice - I followed this advice http://support.apple.com/kb/TS1421 to no avail. For what it's worth, It appears to be isolated to my user account. I also tried uninstalling and deleting all apple software including the itunes folder in my music folder plus deleting the registry keys before reinstalling. I also tried to move th Genius files onto my desktop as per the above suggestions. Any advice?

The itunes application could not be opened. an unknown error occurred (1301

I launched iTunes 9.0.1 today and got this error:
"The itunes application could not be opened. an unknown error occurred (13014)"
An archived tip on the iTunes for Windows forum that suggested deleting the iTunes Library Genius.itdb. That didn't work, I also had to delete iTunes Library Extras.itdb. (For the record I renamed them instead of deleting, but the original post suggested deleting).
Anyway, I thought I'd pass that on in case anyone else experiences this problem.

I had the same error and I keep my iTune folder on an external drive due to size. I tried to create a sub-folder to temporarirly hold the itdb file(s) and give it a try. The system wouldn't let me create the folder, at which point I remembered I had left my mac on but unplugged to find the battery drained in the morning. Upon plugging it in, it came back but then told me I hadn't exjected my external disk. So, I figured there might be a correlation. I tried to eject the disk and it wouldn't let me though no programs were running. So, I went ahead an chose to "Force" the eject via the option it presented me. On the un/re-plugging the disk, I tried to created a subfolder and it worked. Before moving any files to it, I tried starting iTunes again and voila, it worked. So, I suspect the comment above about files being locked is what bit me. Hope this helps...

I am getting the following error message - the itunes application could not be opened - an unknown error occurred (-50). Help!? It won't even open up.

I reinstalled iTunes because it stopped opening up and now I'm getting this error message when it refuses to to open. Help?

If you right-click iTunes and Show in Finder, is it located in the Applications folder?
Try trashing the iTunes plist files from ~/Library/Preferences/ and relaunch iTunes (all of the fies that have com.apple.iTunes in the name).
If that doesn't work, try following Apple's document -> Removing iTunes for Mac OS X.
WTH.

Try removing the Genius database. In the "Finder" go to the /username/Music/iTunes/ folder and delete the "iTunes Library Genius.itdb" file. This may allow the program to launch again. This file will be recreated upon first use of the "Genius" feature.

Advice?

My suspicion is a damaged Apple Application Support. Although they're given for different messages, I'd try the 32 or 64 bit instructions from the following topic (depending on whether or not you're 32 bit or 64 bit ... there's instructions on how to determine which you are in the topic too):

I have followed all suggestions but still my iPad screen is locked with a iTunes logo and a USB cable beneath it, wish I had never bothered
to update it now. Any help would be appreciated. rg

When I restart my iPad the connect to iTunes comes up and stays on until it shuts down again, I have read a report from Apple support suggesting I reinstall iTunes so I might try that again and also your suggestion which i shall also try, but thanks again - rg1547

When I attempt to upgrade an app in iTunes for windows, I get an error: "Could not purchase. An unknown error occurred (11111). There was an error in the iTunes Store. Please try again later"

When I attempt to upgrade an app in iTunes for windows, I get an error: "Could not purchase. An unknown error occurred (11111). There was an error in the iTunes Store. Please try again later"
I am running the latest iTunes 10.7.0.21 for Windows 7.
This error occurs if I try to either update the app or if I delete it and attempt to redownload.
I have an iPhone and an iPad. I am unable to update the apps or install the apps from within the App Store on iOS.
I do not have an AOL ID, as is a common issue with this type of error.
From what I can tell, my Apple ID account seems fine. I logged in, changed some information, and ensured my credit card is valid and updated.
I can download new apps just fine. I am unable to update or install apps I have purchased in the past.

After 30 minutes this morning, no resolution. Then another tech support call this afternoon, 15 minutes in, was escalated to a Tier 2 (Senior) advisor. He said something similar to the above ("this is one of the strangest things I've seen"). He was chatted with iTunes guys and took all my info into the case and was escalating it over to engineering. Said they would be in touch.
So, no solution...yet.
Just to clarify:
iTunes on Windows7: trying to update an existing app, or re-download a prior app, gives the (11111) error. Downloading a new (free) app worked fine.
App Store on iPhone5, iOS 6.0.1: click on UPDATE, switches to INSTALLING...for a second, then switches back to UPDATE. No error message (and nothing in Diagnostic data).
App Store on iPad 3, iOS 6.0.1: same as iPhone 5.
Definitely account related.
I have cleared the store cache, signed out and back in, deleted the credit card data, and re-added, rebooting PC and iPhone...nothing works.
Will post if I hear anything back from Apple.

Instructions to get the phone back working temporary.. till there is a real fix.
1. turn off the phone
2. fire up iTunes
3. press and hold the home button, plug in the cable, hold till you get to see the recovery mode
4. iTunes will the allow to choose restore the phone back to 5.0.1 ( no other choice)
5. iTunes will then ask you to choose which previous backup to would like to recover.
(note: please do not reboot your phone unless necessary, i realize at times after reboot, it goes back to sq1)

The iPod 'iPod' could not be restored.An unknown error occured(9).

I got my iPTouch 16 GB on Oct.13 and on hooking to XP SP2 PC got it on the iTunes ver 7.4.3.1, was able to download music after charging. iTunes showed that a new software ver 1.1.1 for iPTouch was available(of150MB).Got it downloaded to iTunes but when it started to download to iPTouch, it failed and asked to do resotre. All this happened in just few hours of getting it.
Since then, even after reinstalling the iTunes, my iPTouch is not going beyond showing the icon of a plug and a CD.Every time iTune is able to detect the iPTouch saying that it has detected an iPod in recovery mode, you must restore it. And on doing so that error of 'The iPod 'iPod' could not be restored.An unknown error occured(9).' comes up and it again asks to restore.
Though every time iTunes is able to detect an iPTouch, my XP does not show it in 'my computer' as any hooked device or drive.
May I request Apple and other members on this forum to help me out. It is clearly a software problem.
Many thanks in advance.

Thanks to all members for sharing in. In my case finally, I got a brand new replacement from Apple through their Authorised Service Provider,A-1 Infotech, Mumbai. Since in India, Apple does not have a widespread presence,the service and support I got was amazing.
In my case though I never came to know whether the problem was of software or hardware, but the simultaneous step I had taken was to call the toll free number of Apple in India and got my problem registered. Since the iPod Touch was under warranty, I got it replaced without much hassels. I advise the same path for other users and if possible get the additional Apple Care Protection Plan for additional one more year.
Though I have yet to find out how to avail that Protection Plan in India.
Best wishes,

"the iphone could not be restored an unknown error occurred (2)"

Yesterday I connected my iPhone 4 to my Windows 7 laptop, and went through to install the latest security update for iPhone through iTunes. When it was installing the software update, the phone froaze, and then this happened:"the iphone could not be restored an unknown error occurred (2)"
Now, I have uninstalled and reinstalled both Bonjour and iTunes, to no avail. I have done the iPhone reboot method, and the phone will be identified as "iPhone" but not recognised as mine. iTunes states this phone is in recovery mode and I have tried numerous times to restore it.
Windows doesn't detect the phone while this is happening. It will not restore and the error is still popping up. I have followed as many threads to rectify this but nothing seems to be working.
I can resore it on my iMac but the reset date for the iPhone on this computer is six months old.
Any suggestions?

When you say you uninstalled iTunes and reinstalled it, did you follow the directions in this Apple support document exactly? http://support.apple.com/kb/HT1923
That will make a difference on Windows computers. After that, try and reconnect and restore.

My iPhone 3GS 16gb, is stuck in restore mode, downloaded and tried to do a restore multiple times. Keep getting an error The iPhone "iPhone" could not be restored. Unknown error occured (-1). Cannot get it out of restore mode, keeps rebooting!

I have tried to hold the "home" and "power" button to reboot
I have tried powering it off
I have tried, to unplug the cable, hold the "home" button and then plug it in.
Can't check the SN or warranty, cause it is stuck in restore mode.
Is the hard drive gone? Should there be something replaced.

Error 1 or -1
This may indicate a hardware issue with your device. Follow Troubleshooting security software issues, and restore your device on a different known-good computer. If the errors persist on another computer, the device may need service.
Usually this is caused by your antivirus or firewall blocking iTunes access to the Internet. It can also occur if the phone is jailbroken or if the computer you are using was ever used to jailbreak an iDevice.

Could not be restored. an unknown error occurred (1669)

Dears,
Thank you in advance for your usual support as a community.
Here is my issue,
When I try to restore my iPhone 5 from a backup using iTunes, I get an error message 'could not be restored. an unknown error occurred (1669)’.
I tried Apple articles and everything fine with my mac.
please help me as I have been checking this issue for 5 days with no luck.
I am pretty sure that there is a solution for such an issue and for sure it does not make sense to through this device away with no solution.
Thank you again.

The apple support articles doesn't mention anything about the MAC.
Is your iphone jailbroken? Per apple support page this is a hardware issue.
Check for hardware issues

These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.
Check that your security software and settings aren't preventing your device from communicating with the Apple update server.
Then try to restore your iOS device two more times while connected with a cable, computer, and network you know are good.
Confirm that your security software and settings are allowing communication between your device and update servers.
If you still see the error message when you update or restore, contact Apple support.
Check for outdated or modified software
Related errors: 1015, “The required resource can't be found.”You might see these error messages if any of these are true:
Your device has a beta version of iOS.
You're trying to install an earlier version of iOS (downgrading).
Your device has unauthorized modifications to iOS, also called "jailbreaking."
Use recovery mode to restore your device to the latest version of iOS.
