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. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, 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. (If you've got XP, although the procedure is for Vista and 7, 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.)

Same exact problem. Using Windows 7.


Restart did not help.


Control panel -- Programs & Features -- Apple Application Support -- then click "Repair" ==> did not work. Tried reboot after that too, and it did not work.


Any other suggestions? would rather not reinstall all of iTunes 10.7 (since I can't even find iTunes 11 now to download -- at least not yet, I guess it is only available now through the update).


Thanks!

Update .netframework to latest version (see apple support)


Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)

You will also need to check and verify that the following folders have been removed:

  • C:\Program Files\Bonjour
  • C:\Program Files\Common Files\Apple
  • C:\Program Files\iTunes
  • C:\Program Files\iPod
  • C:\Program Files\QuickTime
  • C:\Windows\System32\QuickTime
  • C:\Windows\System32\QuickTimeVR


dont forget to remove icloud also

you dont need to delete your itune music library though


If any of these folders still exist, delete them along with their contents. (if you cant delete them, right click and go to properties and then security and change the control of the fold to you)

do this for files under program files and program file (x86) on your computer


once you have deleted everything, restart your computer. Then I repaired my registry using a registry repair program.


Important:- instead of installing itunes I installed quick time, which installs apple application support (this is the corrupt file which is causing all the issues)


i then installed itunes and it all worked fine,


should take no longer than half hour to fix 🙂


hope this helps

I have exactly the same problem. This after an "update" was installed and I had spent the previous day getting iTunes to work. If I may pose a question based on my long time experience: does Apple deliberately sabotage software for a Windows PC to try and get one to purchase their products? I have ENDLESS problems with iCloud, iTunes, Quicktime etc on my PC and the strange thing is I never experience problems on my iPhone or iPad. I am suspicious.

No. Stuff happens. Sounds like you're sorted for now, but for anyone else having problems...




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 page in case one of them applies.


Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
