Cannot open iTunes: Unknown error (-50)

Greetings,
Just trying to open iTunes ang go to Applications - which worked with no trouble up to right now - and get the following error:
"We could not complete your iTunes Store request. An unknown error occurred (-50)"
I have seen references in the forums regarding this error code, but usually in regard to syncing issues.
I must note that right prior to this incident, I was actually browsing the French iTunes App selections. Perhaps my iTunes is now continuing to want to access the French iTune store??
Will appreciate any pointers!
- Roger T

I experienced exactly the same problem. Everything was just running ok, but after visiting a french site application store, connectivity to apple store became impossible and error (-50) was detected. Itunes reinstalled, firewall disabled but at present no way to solve the problem

Just downloaded Itunes 10.6 on windows7 64bit and now cannot open Itunes get error msg:ITunes Library.itl cannot be read because it was created by a newer version of iTunes.Tried uninstall and reinstall any help ? Thanks

Even I am facing a similar problem. Initially the iTunes worked on my windows 64bit edition. Ever since I downloaded the latest version it has stopped identifying my 4S with an error msg that asks me to download the 64bit edition. I have tried it again and again but it did not help. After unistalling and downloading again the new error msg says " the file- iTuneslibrary.itl cannot be read because it was created by a newer version of iTunes". Please help!!!!!!!

Cannot open itunes. Error message

I tried to open itunes and it said that there was a quicktime error. I downloaded quicktime and tried itunes again and got this message. "iTunes has encountered a problem and needs to close. We are sorry for the inconvenience." I have downloaded, unistalled and downloaded itunes and quicktime several times. I have rebooted and waited and nothing has fixed this error. It has been over a week and I still cannot access it. What can I do?

Try and use Microsoft's Cleanup Utility and then reinstall Quicktime/iTunes:

Cannot open Itunes- Microsoft error

Every time I try to open Itunes 7.1 I get a Microsoft error saying it encountered a problem and needs to close. I have tried installing and reinstalling and It continues to come up with this message and it will not open. Any suggestions? I should never have decided to try to upgrade.

I have a K-Lite codec pack installed on my computer, I don't remember what version but its been less than a month since I downloaded the it. Are their any known problems between the two?
afraid so. the problems usually arise when the versions of the QuickTime codecs that come with the Pack are out of sync with the mimimum QT version requirement for the particular version of itunes you're running.
for example, itunes 5.0.x required at least QT 7.0.2, and K-lite Packs with the QT 6.5.2.10 codecs broke QT 7.0.2, which broke itunes 5.0.x.
itunes 6.0.x required at least QT 7.0.3 ... and ACE Packs containing the QT 6.5.2.10 codes would break that.
itunes 7.0.x requires at least QT 7.1.3. i've already seen a report of a version of the ACE Pack breaking QT 7.1.3:
http://discussions.apple.com/click.jspa?searchID=-1&messageID=3226147
... and a report of a K-lite Pack containing the QT 7.0.3 codecs breaking a QT 7.1.3:
http://discussions.apple.com/click.jspa?searchID=-1&messageID=3311325
it might not just be the codec mismatch that is causing the grief. in at least one case i've seen a report of a K-Lite pack installing an earlier version of qttask.exe (it's a quicktime background process and startup item) on a PC, and and a version mismatch between your QuickTime Player and qttask.exe could cause all manner of grief when upgrading or launching QT:
http://discussions.apple.com/click.jspa?searchID=-1&messageID=3212208
... but whatever the precise mechanism, the upshot is that the mega codec packs can break your QuickTime in nasty ways, resulting in a broken itunes that won't launch.

If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

I downloaded the latest version of itunes. Now I cannot open iTunes. I receive this error message: The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll. Thoughts?

I downloaded the latest version of iTunes on my PC. Now I cannot open iTunes. I receive the following error message: "The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll" After pressing the "OK" button I receive a second error message: 'iTunes not installed correctly. Please reinstall iTunes. Error 7 (Windows error 127)". I've uninstalled iTunes and reinstalled to no avail. I've also eliminated the temp files (per suggestions on the trouble-shooting page) and no luck. I also tried system restore and that did not fix the problem. Any thougths on a repair?

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. Head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (Although the procedure is for Vista and 7 and you've got XP, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)
Re: I recently updated to vista service pack 2 and I updated to itunes 10.2.1 and ever since I did that my itunes won't open any more. Itunes starts but before anything loads a

Recently I updated my iTunes account, but there was an error during installation. Now I cannot open iTunes as an error message appears. If I delete iTunes from my laptop then reinstall, will I still have access to all my music etc?

The reason why I ask, is because I have another laptop which I then installed iTunes on (this was to overcome the issue of the error message and reduce the risk of losing my music etc. on my first laptop). I cannot see any of my music on the second laptop, even when I attach my iPod. I authorised the second laptop to link but as I cannot open iTunes on my first laptop, I cannot access my music. I'm assuming iTunes accounts are only stored on individual laptops/PCs and cannot be accessed remotely?? Or am I doing something wrong? I'm not sure what I can do.

Your iTunes library, media, playlists, and iOS device backups are safe. Please visitTroubleshooting issues with iTunes for Windows updates for details. The steps in the second box should get iTunes back on track.
I don't make any use of the homesharing feature so I can't really comment on it, but if you want to change which computer you use to manage your devices see this migrate iTunes library post.
