After trying to install the new update, I am getting a message from Windows saying that an MC file is missing, reintall Itunes-which I have now done 3 times. How do I fix this?

I received the new update from Itunes and after installing, I couldnt get into my Itunes. I get a message from Windows saying that an MC file is missing and to reinstall I tunes. I have reinstalled 3 times, the first time I didn't remove the old version, I installed the update over it. Next I tried the repair function under Control Panel. After that, I uninstalled Itunes and reinstalled again from the website. I still get the same message about missing files from Windows.

There are two ways that a backup can become encrypted:
You chose to encrypt it, then forgot the password.
If you have company-provided MS Exchange access your IT department has the option of requiring your backup to be encrypted. The first time you backed up or synced after installing MS Exchange you were prompted for a password. That is the password you need.
If you don't have the password any longer there is no way to restore the backup.

I have tried to install the new update and...

I have tried to install the new update and i have lost everything on my phone and just asks to plug into itunes. I have finally downloaded the new update and I now have nothing on my phone no apps no nothing even tho it was restored from the back up i did yesterday? Any ideas how to resolve this without downloading everything again. I have the Iphone 4s 64GB which was full (so a LOT on there)

What were you backing up to? Your computer or iCloud? All of your apps and media should already be in the iTunes library on your computer. You should just be able to re-sync them if all else fails.

If this is the problem following the instruction. Frequently it is a hardware problem.
iOS: Wi-Fi or Bluetooth settings grayed out or dim
Otherwise try (assuming that other devices see your network)
- A reset. Nothing wil be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power of and then back on your router.
- Reset network settings: Settings>Genral>Reset>Reset Network Settings

once again I am trying to download the new update 8.1.3 and it says I am not connected to the Internet which I am. Any suggestions ?

Have you tried restarting or resetting your iPad or your router?
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
Even though you are connected to the Internet, sometimes resetting your router can help. It's very easy to do. Just unplug it for about 30 seconds, plug it back in and let it start up.

I cant start itunes after i tried to install the new update PLEASE HELP

Every time i try to open it it said iTune.exe - Entry Point Not Found then it said The procedure entry point kCMByteStreamNotification_AvailableLengthChanged could not be located in the dynamic link library CoreMedia.dll. And i tried re-installing it and it went through but it just wont open.

Hello. No message shown. The downloading does not complete at all, I tried like 20 times but no one worked. The closest I was to downloaded it, was with 66 mb (the new version has 66.1) As stated on the web page of apple I uninstalled itunes and all its accesories or common programs. Now I am unable to install the new version and I am more frustrating since I did it to sincronized it wit my new ipad! In consequence, no message at all, the downloading simply stops at 49%, 67% or 99% :(
Thank you for your time!!

My phone update didn't work. After trying to install the latest update, it downloaded the update and installed then said the computer needed to restart to finish; the computer restarted but now my iphone is not appearing in the list of devices in itunes.

The phone itself is not working either. It shows the apple icon and a horizontal bar (black outlined in white). Thanks in advance for any help.

You need to press the power button and the home button at the same time for a few seconds until your phone does a recovery. At least you will have a phone that works with all your contacts. But then you will have the same problem alot of other people are having since this update. You will lose all your music and apps. When you plug into ITunes it will have 2 options after that. Restore from back-up or set up like new. Back-up does nothing and restore to new you will lose everthing (music, Apps)). The only fix so far after your recovery is to plug your phone into another puter that has your ITunes account on it. It doesn't have to have any music or apps, just an account so you can sync your phone. After that plug your phone back into the puter with all your stuff on it and it will re-sync and add all your stuff...Hope this helps

I unloaded some mp3 songs into desktop file by mistake, now I get a message Item "....." is used by Mac OS X and cannont be opened. How can I fix this

I am new to this support community. I was givin a stick with a bunch of music on it, I wanted to install it on my music and have never done any installations. The 3000 some songs got into my system 3 times so I have 6000 some in my desktop file and had ( I deleted or lost it somewhere??) 9000 some in my documents file. When I click on a song I get a message... Item "Alan Jackson - My Own Kind Of Hat 2.mp3" is used by Mac OS X and cannot be opened.
1. What can I do to clean these files out ?
2. What does this message indicate?
3. I did manage to trash some of the songs But had another message that sounded like I should not attempt this either.
Any help would be appreciated.

I have exactly the same problem. I have tried Applejack and TechTools Pro to correct permissions and the files are still unaccessible.
The computer is a 2x3 GHz Dual-core Intel Xeon w/16GB Memory, running OS X 10.4.10.
I too would greatly appreciate a hint on how to access these files.

Help!!!
I now have a brick for a phone. Just tried to update to 7.1.1 using iTunes and it wipred out the operating system OK but now will not communicate with iTunes or the laptop. I reloaded iTunes and still no luck. If I press and hold the power and home buttons it inly comes up to the same screen showing the lightning cable pointing to iTunes logo. How can I get this running again? Even a factory reset to start would help if possible then I can do a restore. Right now it is worthless.

Hello HarbourStables,
Thank you for the details of the issue you are experiencing with your iPhone 5s. I would be concerned too if my iPhone was stuck in recovery mode and not recognized in iTunes so that you can restore it.
I recommend the following article for the issue you described and specifically this step:
5. Use iTunes to restore your device.
If you don't see your device in iTunes, follow these steps for Mac or these for Windows.
Find the full article here:
