iTunes cannot run because some of it's required files are missing.

I am having the same problem. When this happens, I have to uninstall iTunes, download the newest version from the site and then re-install it.

Don't worry about all your music and organisation, that is safely hidden in your music folder in the iTunes folder(PC), so when you uninstall and re-install, all your files will be as you left them.

Will this actually bring awareness? If so, then thank you. I'm not having the missing files problem, my iTunes won't even bother to launch and isn't even running in the background anywhere, it's as if, although all the files are present on my drive, windows doesn't recognise that it even exists! Tried all suggested solutions, my suggestion? Apple release another windows update that works! I am actually pretty much fed up now of this, been trying for days to get iTunes to work, short of actually wiping my laptop clean and starting again, which I may add, I am most certainly not prepared to do! I am glad however, that I am not the only one having problems, though some people seem to get theirs working with some of the suggestions listed, I cannot understand why I can't fix mines 😟

I keep getting this message. Have uninstalled and reinstalled twice and it keeps happening. Any help would be appreciated. Starting to drive me a bit mad!!

I have just tried to download latest version and it stopped halfway through then came up with message about insufficient privileges to access directory C:\program files\common files\Apple\CoreFP then said to log in as admin, which I already am. Retry does same thing, so cancelled. When I run Itunes it says files missing. Tried to install previous repair and same message.

I am at my wits end, have had endless problems with the ipod. I'm totally frustrated as I now cannot open my itunes icon on my pc as I'm getting the message "some of it's required files are missing".Will I definitely not loose my library if I reinstall? Also thinking of reinstalling previous version, is that available on the Apple site? Any comments/suggestions would be great. Many thanks

Yes. Same problem here, both my account and my partners account. Am not willing to try and re-install until i get a guaranteed comfirmation from Apple support that i wont lose any of my library/apps etc. Still waiting on a response from Apple though, so much for response within 24 hours!!!!

Same problem. AGAIN! This happened after the last update.

Pathetic. I am so fed up of Apple updates messing my machine and settings up. Totally inadequate support. This happens FAR TO OFTEN APPLE. What are you playing at?

Same problem here. Just installed the latest version of iTunes (having only installed a new verison a couple of weeks ago), restarted my computer as required only to be told that 'iTunes cannot run...' Then went to the iTunes website, attempting to reinstall iTunes as requested, only to be told that I already have the latest verison of iTunes. So am now stuck, unable to access to my library or to get into the programme to try and do anything.

Pretty ****** off right now, but at least it sounds like it's not just me experiencing this problem.

Okay this might help some of you. The default download is for 32bit OS (I'm using Windows7), on the apple site there is an option for 64bit also, I downloaded this and all works fine. By the way I uninstalled everything first via control panel in the order specified by apple within their uninstall instructions. I hope this helps. No doubt this is not the end of it as I fear making any updates to v 10 intunes!! I now have to go and iron all my husbands shirts as he found and fixed this problem for me!!

How I fixed this problem without re-installing

1 - Dragged the entire Itunes folder from my 'Music' folder to the desktop
2 - Went to http://www.apple.com/uk/itunes/download and downloaded latest version
3 - On install screen it gave options Repair or Remove, done the Repair
4 - Itunes now running but all my files gone so,
5 - Back to my 'Music' folder & deleted the new Itunes folder
6 - Dragged the original Itunes folder, now on my desktop, back into the 'Music' folder
7 - Sorted. All my music, videos & apps are there!

Hope that works for you, saved me doing a whole reinstall which I hate doing

Thanks stvicious,

I had the same problem as everyone else here. Followed the above, backed up all files first, although it was not needed. Ran the installer under 'repair' and everything is back to normal.

Thanks,

Liam

@ stvicious. Many thanks. Much better than the uninstall/re-install that apple support recommended.

I have just had this problem with my iTunes about 20 mins ago however i updated iTunes a few days ago and it has been fine until now.
I managed to rectify the problem by going to the control panel > programs > itunes, i then right clicked on itunes and selected repair and voila about 2 mins later all done back up and running again.

I'm having the exact same problem. I've tried EVERYTHING. It won't even let me uninstall now! I've unistalled all the apple programs except itunes and bonjour. It will not allow me to do either! I have a new Ipad, and am very UPSET that ITUNES isn't working! Grrr!
