iTunes has stopped working

I have finally resolved this. The issue was with my version of Windows 7 Professional SP1 64 bit.

The solution was a "repair install" or "upgrading" the operating system to the same version from the installation DVD. Instructions for doing this are on the sitehttp://www.sevenforums.com/tutorials/3413-repair-install.html.

Apple iTunes Store Customer Support and the Apple Support Team provided friendly assistance. Diagnostics tests and files sent showed nothing was obviously wrong except there was an exception thrown by WebKit.dll in Apple Application Support. I knew this already. They said there was a Microsoft certificates corruption issue and should reinstall the whole system.

I ran sfc /scannow from an elevated command prompt (run as Administrator) several times and found two issues:

1. t2embed.dll could not be checked.

2. _isdel.exe was missing from C:\Windows\SysWOW64\InstallShield.

Issue 1 was probably caused by a workaround for the Duqu security vulnerability. User gn_id posted a solution for this on December 5, 2012 in this forum that involves running Microsoft Fixit 50793, please see http://support.microsoft.com/kb/2639417.

Issue 2 was probably caused by Malwarebytes' Anti-Malware. It led to deleting _isdel.exe from its quarantine. In November 2012, the program gave false positive reports for the "Trojan.zbot" (http://forums.malwarebytes.org/index.php?showtopic=117549).

sfc /scannow reported the _isdel.exe was missing and it could not repair the member file. I copied the source version of _isdel.exe from the installation DVD to C:\Windows\SysWOW64\InstallShield after extracting it with 7-Zip FIle Manager, but there was no change with sfc /scannow and iTunes kept crashing when I tried to connect to the iTunes Store. I could still update podcasts and apps, and sync my iPod and iPhone.

Finally, I decided to do a repair install as a last resort, short of upgrading to Windows 8. This keeps existing user files. I took a backup first of all files. The system rebooted about four times and you it rebooted from the hard drive, not the DVD. After this, sfc /scannow worked and iTunes 11.0.4.4 could connect to the iTunes Store and display its contents.

I hope this is useful to others with a similar issue.

To be frank, I believe Apple is worse than Microsoft when it comes to fixing bugs. It is their problem not Microsoft. The same applies to many other things.

Hi Wizard,

This will work for you. Upgrade to the lastest version of itunes 11.1. Restart your pc. Then copy file QTMovieWin.dll from c:\program files (x86)\common files\apple\apple application support

To: C:\program files(X86)\itunes folder

Please copy the file do not move it.

This will work for most of the problems on here.

This should work:

- Make sure iTunes is closed

- Open Control Panel

- Click uninstall a program

- Click once on iTunes

- Click on 'Repair' at the top

- Wait for It to do its thing...

- Fixed (hopefully)

Joe -39, Works!

Ok.

3 days ago, for no apparent reason my itunes stopped working.

This only happens after it has "synced" with the itunes store and prepares to upload remaining songs.

NOTHING has changed since then other than downloading latest itunes (11.1...whatever) which i was recommended to do after it stopped working.

I am using windows 7

Latest itunes version (for windows)

I have thousand of songs in icloud, which were uploading fine until 3 days ago.

Windows message reads something like: Itunes has stopped working properly, windows will now close the programme blah blah balh.

Bit annoyed. Tried copying the dll file from QT that somebody mentioned earlier. Also tried "repairing" programme and re-downloading update.

Not working still!!!! HELP PLEASE!!!

This solution worked for me!!! Thanks a million! Everyone, please give this a try. It is a simple procedure, and worth the try!!!

i am getting the same problem what should i do. please help

Such errors can usually be fixed by deleting the offending dll, then repairing the component it is part of from the programs and features control panel. CoreAudioToolbox.dll is part of Apple Application Support and can normally be found in

• C:\Program Files\Common Files\Apple\Apple Application Support or
• C:\Program Files (x86)\Common Files\Apple\Apple Application Support

where the name of the Program Files folder may vary by region.

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with third party software.

Your library should be unaffected by these steps but there also links to backup and recovery advice should it be needed.
