itunes cannot run because some of its required files are missing

It's possible, and more likely to get help, to post without cursing.

If I say I have exactly the same problem as husband and promise not to curse, can you or someone else tell me what to do to solve this sudden problem? I've removed itunes and quicktime just as instructed by the on-line troubleshooting. Same old same old. But fortunately, my ipod has decided not to work either, so maybe this is all moot.

Still, my kids want their tunes.

Signed,

Really frustrated

Apple released that update to iTunes on Friday, and they do not have any resolutions to the problems Windows XP and Vista users have been encountering. The common errors have to do with the general error message - "iTunes cannot run because some of its required files are missing. Please reinstall iTunes." Installing a different version of QuickTime doesn't resolve anything either, due to the fact that when you install iTunes the imbedded QuickTime installs over whatever version you installed before that. Some users are also having troubles getting their iPods and iPhones being recognized by iTunes.

In the mean time, to get a working copy of iTunes:

Go to http://www.oldversion.com/

From the drop down list select "iTunes," and then scroll down to the newest version at the bottom, the second release after iTunes 7 (the last one). Download that version, and the error shouldn't occur anymore. This should fix your problem... Although I am not able to get iTunes to recognize my iPhone. All this has been happening since the newest update to iTunes was downloaded.

Latest Apple solution is :
