Unable to install iTunes 12.1.2

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 installation or performance issues, or compatibility with QuickTime or third party software.

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

Well I would start with the direct download links since so far we don't know what the installation issue was. If you need to uninstall then as long as you only uninstall the application and leave the library folders alone there is nothing to worry about. That said you should maintain a

backup of your library.

I had a similar problem and it drove me nuts for a couple days. I tried everything my tiny brain could produce and also tt2's suggestion on deleting and attempting to reinstall. Anyway, bottom line...... I downloaded and installed the iTunes for older video cards and it worked first time. Have no idea what or why. I'm done and may never upgrade again!! Good luck. Give it a try:

iTunes 12.1.2 for Windows (64-bit — for older video cards)

Archway Jack is running 32-bit Windows 7, so he should definitely not try the "64-bit -- for older video cards" version.

I had a very similar problem attempting to update to 12.1.2 on April 9 (running 32-bit Vista). I solved it along the lines suggested by turingtest2.

Sorry, you're right. I didn't catch that he's running W7 32 bit. 😮

It's interesting that this thread can no longer be found by Google search, which is how I found it in the first place. The manner in which my previous post was edited is also interesting. Here's a similar thread: update 12.1.2 won't download and won't update. invalid signature

A day later and both threads can be found via Google. Pardon my paranoia, if that's all it was?

This is Jive. Anything can happen. 😝

I had this problem too, I found that the Apple Mobile Device Service would not start. I checked my services and found that it was disabled, so I set it to manual and it finished the install right away
