Q: Fix for iTunes update 11.1.4 issues

I had this problem and followed the recommended solution (less the admin and re-boot suggestion) and it was successful.

Thanks for your post. I'm having the same problem. Two quick questions: does one have to reinstall the Apple programs that have been deleted? Second, will the missing MSVCR80.dll be reinstalled with this fix?

Once you've cleaned out the existing components reinstalling iTunes should replace everytjing that it needs to work and resolve the start-up error.

MSVR80 was corrected. Apple Application Support,Bonjour, Apple Software Update, itunes and Apple Mobile Device Support all magically re-installed as part of 11.1.4.

Thanks everybody who have responded so promptly. It worked like a dream!  Thanks once again.

You're welcome.

had problems with update 11.1.4.  Did the download only option which was suggested when problem occurred.  ran intunes installer by itself.  still didn't work so followed instructions here to uninstall from windows itunes, apple software update, apple mobile device support, bonjour and apple application support in that order.  apple mobile deive support did not uninstall.  downloaded latest version of itunes from apple.  restarted computer and installed the new downloaded version which installed fine.  however, now when try to start itunes, the message Itunes LibrARY.ITL CANNOT BE READ BECAUSE IT WAS CREATED BY A NEWER VERSION OF ITUNES.  Now what do I do?  I assume this is result of running itunes installer from download only.
