update 11.1.4 won't install on my laptop. Now I can't get iTunes to work at all.

Reinstalling iTunes or running its repair process alone won't resolve the problem. You need to work through the following process...

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)

Remove all of these items in the following order:

• iTunes
• Apple Software Update
• Apple Mobile Device Support (if this won't uninstall press on)
• Bonjour
• Apple Application Support

Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.

See also HT1925: Removing and Reinstalling iTunes for Windows XP or HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8. Some users may need to follow all the steps in the appropriate support document which includes some additional manual file and folder deletions not mentioned above.

It worked - huge thanks!

What is the problem anyway? Is there a bug in the update?

You're welcome. It would seem there is some sort of issue with the installer for some people but it isn't causing a problem for everyone so isolating the exact cause might be tricky. Thankfully that isn't my headache!

Thank you for this information. My iTunes had this update problem this morning on my Windows 7 machine. I had one problem, Apple Mobile Device Support refused to uninstall using the normal Windows Unistall program so I ended up using CCleaner to remove it. After that I was able to follow through and get iTunes installed and running again.🙂

Thank you again for the useful information!

You're welcome. 🙂

Good morning tt2, having the same problem with msvcr80 and itunes1.4. Followed all instructions and was able to remove all but the mobile device. Installed 10.3.1 but won't open, I get a new pop up saying "iTunes library itl" cannot be read because it was created by a newer version of iTunes. Please help

See Empty/corrupt library after upgrade/crash. Either your library was updated by iTunes 11.1.1.4.62 so you need to revert to the older one as is required after a downgrade, or some other issue has caused a problem with the library. Alternatively try upgrading to the current build again.

I have the same issue. Most of the music on my ipod is from my CD collection. Does anyone know if I follow tt2's instructions will they all delete??

I don't want to reload 340 CD's.

Thanks!

The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.

Thank you so much for your help, Turingtest! I spent a lot of time on this problem, but once I read your solution, it defintely worked, thereby reducing my agony and saving me additional time!

You're welcome. 🙂

Followed TT2's notes to the T and I'm all good!!

Thank You TT2!! 🙂

Hi, followed your reinstall notes - worked and my itunes is back up and running - thanks For the help- much appreciated

I did it according the turingtest2. Everything worked as described, nothing lost, everything is absolutely the same, as before. Thank you very much, you save my music and my mental health too.

Do the Apple staff read the discussions? They should warn the W7 64 bit users or fix the problem.
