Hello Diana,
Thank you for the details of the issue you are experiencing with installing the latest version of iTunes. I recommend following the steps below:
Resolution
Follow these steps to resolve the issue:
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.
I understand that you have already uninstalled iTunes, but when you get to this step, it is important to uninstall iTunes and the related components in the order listed in the link for that step. You can find the full article here:

I recommend the following article if you continue to receive an error:

Are you downloading iTunes form an Apple website or somewhere else? If the answer is somewhere else, try downloading it from Apple. Click on iTunes in the black menu bar above and go from there.
Let us know what happens.

Do my itunes purchases keep downloading even when I'm not signed into itunes?

I don't have enough time for my purchases to download completely, and I need to sign out of my itunes account, and I was just wondering, if I sign out without pausing my downloads, will they keep downloading? Because this is what I'm actually hoping for. It would be great if they could keep downloading even when I'm not signed in. I just don't know if they do or not.

Hi junebeez,
Have you gone into Settings and turned off the Sync Courses and Notes option? If not, try doing this:
Go to Settings>iTunes U>Sync Courses and Notes, and see if it is = On. If it is, turn it Off and see if that fixes the problem.
Hope this helps!
Cheers,

HT201210 what if it says itunes could not contact the iphone software update server , what to do ?

what if it says itunes could not contact the iphone software update server , what to do ?

99.9% of the time, the cause of this issue is the fact the phone was jailbroken/hacked to unlock it for use on networks other than the network the phone was originally locked to. Apple maintains a database of officially unlocked iPhones, and when Apple's servers detect phones such as yours, activation stops & you get the message you got.
So, either get a sim card from the carrier your phone was originally locked to, or get it officially unlocked, because it appears that it was not officially unlocked.

Syncing to a new iTunes library or computer will erase your phone. Only if you back up your phone manually before syncing, you can restore your device from that backup again. A manual backup does not include the sync process.
Do this:
Disable autosync in iTunes, connect your phone to your new computer and right click on it in the device list and choose backup. iTunes will backup your device without syncing.
Transfer your purchases the same way, choosing "transfer purchases" this time.
When you connect your phone for the first time, all media content will be erased. But you can restore your settings and app data from your manual backup afterwards.
Don't forget to set up at least one contact and event on your new computer to be able to merge calendars and contacts when you sync the iPhone for the first time.
Music is one way only, from the computer to your device, unless you bought the songs in iTunes and transferred your purchases.
There is 3rd party software out there, but not supported by Apple, see this thread: http://discussions.apple.com/thread.jspa?threadID=2013615&tstart=0

Hi Ahmed,
In iTunes, go to the Store in the left menu, select iTunes Store, wehn it opens, make sure you are on the home screen (icon of a house in the menu bar) and from the righthand side, select Account.
Next you will see all of your account information. Just a little don, you will find: Apple ID overview, there it says, Authorised computers; click on the button to deauthorise.
And you should be done.
Grtz, Carl.

Dear community, what to do when iMovie does not automatically updates video from iPhoto. I've closed and reopen, restarted... still no good

Dear community, what to do when iMovie does not automatically updates video from my iPhoto. Usually it will automatically generate new content, but now it's stuck 3 days behind the latest new iPhoto entries... I've restarted all programs, restarted the computer... what else?

Ezy,
I'm not sure what recourse you really have. My expectation would be that Apple is on the hook to warranty your computer, but they only warrant the machine you've got.
The issue of exchange is fully in the hands of the dealer. If it were Apple, they would likely have had a longer return/exchange period (2 weeks is standard in the US, and I think they use the same timeframe internationally), and there have been some reports of people getting machines exchanged even if they were just outside the 2-week period.
However, with Apple dealers, I think they are a little more concerned about old inventory. Who knows what Apple does when you give them back a last-gen Macbook. They probably sell it at a markdown, but even marked down, they still get a profit (most likely). When an authorized reseller gets stuck with an old machine, they probably have to sell it at a loss. Thus, I would expect resellers to be more afraid of holding onto discontinued models.
That said, if they do a lot of business, they should appreciate the value of customer loyalty: it's usually better to lose money on one purchase than lose a customer (and all their future purchases). If you're a regular customer there, you could point out that disappointment could cause you to go to a competitor. That's playing a bit of hardball though.
However, there is maybe an upshot to all of this... The new 13" model did not get the quad-core CPU's.. And it lost its dedicated graphics adapter. I've seen a decent number of people complaining that the new 13" model is worse than the previous one (the one I'm assuming you've gotten). So it might not be such a bad thing after all.
